The Compaq Professional Workstation
The Compaq Professional Workstation 5100 is an industry standard workstation designed for the
highest performance in a desktop form factor. The Compaq Professional Workstation 5100
supports up to two Pentium II 266MHz, 300MHz, or 333MHz processors with a 512KB L2 cache.
Combined with the Compaq Highly Parallel System Architecture, this workstation provides
customers with industry leading system performance.
To enable the workstation to meet the demanding needs of Financial, CAD, and electronic design
automation (EDA) users, the Compaq Professional Workstation 5100 comes in a 5-bay towerable
desktop form factor with five expansion slots, memory expandable to 512 MB, integrated Wide-
Ultra SCSI controller and an auto-sensing 10/100TX Ethernet NIC. In addition, the Compaq
Professional Workstation 5100 incorporates new technologies such as Remote ROM Flash,
Remote Wakeup, Fail-safe Boot Block ROM, PremierSoundand enhanced multiple monitor
support.
The Compaq Professional Workstations are powerful, industry standard workstations specifically
designed to deliver leading performance with today’s demanding CAD/CAE, digital content
creation (DCC), EDA, and financial analysis applications. The Compaq Professional

Compaq Highly Parallel System Architecture
The Compaq Professional Workstation 5100 has been designed with a Compaq Highly Parallel
System Architecture that maximizes system bandwidth to improve performance in demanding,
resource-intensive applications. Most workstations in the Windows NT / x86 market support two
CPUs to process instructions concurrently. However, overall system bandwidth is limited since
each CPU must compete with the other for access to critical subsystems, such as memory and I/O
whose bandwidth has not been correspondingly increased.
The Compaq Highly Parallel System Architecture used with the Compaq Professional
Workstation 5100 is based on industry standard components and addresses the need for greater
overall system bandwidth by using dual memory controllers, dual-peer PCI buses, and advanced
multiprocessing support.

Diagram 1: Compaq Highly Parallel System Architecture
Dual Memory Controllers
The Compaq Professional Workstation 5100 uses dual memory controllers that can process
memory requests in parallel, effectively increasing overall memory bandwidth. Other
workstations in the Windows NT / x86 market offer memory bandwidth of either 267 MB/second
or 533 MB/second depending on the core logic chipset they use. The Compaq Professional
Workstation 5100 uses two memory controllers, each with memory bandwidth of 533 MB/second.
Therefore, total memory bandwidth increases to 1.07GB/second: two to four times faster than
other systems.

Dual-Peer PCI Buses
The Compaq Professional Workstation 5100 also uses dual-peer PCI buses to increase system I/O
bandwidth. A single PCI bus provides I/O bandwidth of 133 MB/second that must be shared by
many key peripherals such as the graphics controller, hard disk, and NIC. With dual-peer PCI
buses, each bus can provide peek bandwidth in parallel with the other controller, allowing an
aggregate I/O bandwidth of 267 MB/second. This provides twice the bandwidth of single bus
architectures. Also, dual PCI buses allow key peripherals to be connected to separate buses to
balance overall system throughput.
Diagram 3: Dual Peer PCI Buses
Optimized Multiprocessing Support
Finally, with dual memory controllers and dual peer-PCI buses, the Compaq Professional
Workstations 5100 is able to deliver optimized multiprocessing support. The Intel Pentium II and
Pentium Pro processors enable multiprocessor support by including circuitry that determines how
multiple processors can share the CPU bus. However, most multiprocessing implementations in
the Windows NT / x86 workstation market take advantage of this support by simply adding an
additional processor to an already existing desktop design. Compaq takes multiprocessing to the
next step with the Compaq Highly Parallel System Architecture by enhancing memory and I/O
bandwidth. Multiprocessor systems designed without the Compaq Highly Parallel System
Architecture will quickly encounter a bottleneck as the multiple processors try to access the other
system resources, such as memory and I/O subsystems, that have not been enhanced to
accommodate the additional data traffic. The Compaq Highly Parallel System Architecture
significantly reduces these bottlenecks by incorporating enhanced subsystem resources, such as
dual memory controllers and dual peer-PCI buses, to accommodate the increased data traffic from
the multiple CPUs.

Processor Technology
The Compaq Professional Workstation 5100 uses Intel’s newest processor which incorporates
Dynamic Execution, MMXtechnology, Dual Independent Bus architecture and advanced
multiprocessing support technologies to provide the highest performance workstation.
Dynamic Execution
The Pentium II processor design is based on Intel’s Dynamic Execution technology that combines
three advanced processing techniques to increase the performance. The three techniques are
multiple branch prediction, dataflow analysis and speculative execution.
Multiple branch prediction means that the processor looks ahead several steps in the software and
predicts which groups of instructions are likely to be processed next. This increases the amount of
work delivered to the processor, improving how efficiently the processor is used and ultimately,
system performance.
Dataflow analysis analyzes which instructions are dependent on each other's results, or data. This
technique allows an optimized schedule of instructions to be created so they can be processed in
the most efficient order.
Speculative Execution means that the instructions are then carried out based on the schedule
created by the dataflow analysis. Thus, the entire processor's superscalar processing power is kept
busy, boosting overall software performance.
This combination of new technology enables the Pentium II processor to deliver the processing
performance workstation applications requires.
Dual Independent Bus Architecture
The Pentium II uses Intel’s Dual Independent Bus architecture providing two (dual) independent
buses versus the single bus architecture of the Pentium processor. The dual buses are the L2-
cache-to-processor bus and the processor-to-main-memory system bus. This design delivers up to
three times the bandwidth of a single bus architecture processor because the buses can work
independently which essentially doubles the throughput. This technology will enable the evolution
of today’s 66MHz system memory bus to the faster 100MHz system memory bus.
Pentium II
The Compaq Professional Workstation 5100 uses the Pentium II processor, which is Intel’s
newest processor that incorporates x86 technology along with Intel’s new MMX processor
instruction set. The Pentium II will come in 233MHz, 266MHz, 300MHz, and 333MHz versions
with 512KB L2 cache. Once again, because performance is a primary requirement for
workstation customers, the Compaq Professional Workstation 5100 will only use the
266MHz/512KB, 300MHz/512KB, and 333MHz/512KB processors.
To improve manufacturability, the Pentium II uses a new form factor. Instead of the traditional
single chip package, the Pentium II comes with the processor and cache mounted on a printed
circuit board (PCB). The PCB, processor and L2 cache are enclosed in a Single Edge Contact
(S.E.C.) cartridge. Instead of a socket, the Pentium II now plugs into a slot using the S.E.C.
cartridge. This new form factor is similar to a video game cartridge in appearance and measures
approximately 4.9” wide by 2.1” high by 0.5” deep.
The Pentium II provides some enhancements over the Pentium Pro. The MMX instruction set
improves performance of multimedia processing in MMX-enabled applications. Additionally, the
Pentium II uses industry standard SRAMs for the L2 cache. However, the SRAMs run at half the
core frequency of the processor. The replacement of the full-speed secondary (L2) internal cache

(Pentium Pro) with the industry standard SRAM cache improves manufacturability, however, this
new design takes longer to access the L2 cache versus the Pentium Pro. To compensate for the
reduced L2 cache performance, the Pentium II incorporates twice the internal L1 (primary) cache
of the Pentium Pro.
The new design also places some limitations on scalability. The current Pentium II systems will
only be able to support up to two processors and will be limited to 512 MB of addressable system
memory. The Pentium II is only capable of caching 512 MB of system memory so adding memory
beyond this will significantly degrade system performance.
Graphics

3D Capabilities
Although the Millennium II has improved its 3D capabilities as compared to the original
Millennium graphics controller, there are significant differences between it and other 3D graphics
controllers offered on the Compaq Professional Workstation 5100. The new features in the
Millennium II support texture mapping andGouraud shading along with 32-bit Z-buffering. The
Millennium II does not support fogging, alpha-blending, depth-queuing, MIP-mapping, anti-
aliasing and bilinear interpolation making it inappropriate for applications in the CAD and DCC
segments that require this level of 3D functionality.
Additionally, the Millennium II 3D capabilities are implemented mainly through software (i.e.
drivers). Thus, those functions not supported by the hardware graphics controller must be
emulated in software and processed by the CPU. This has a significant impact on performance
and makes it far slower than a hardware-based implementation. The Millennium II 3D graphics
capabilities make it appropriate for 3D games, viewing 3D web sites, and entry-level CAD where
rudimentary, low cost 3D capabilities are needed.

ELSA GLoria Synergy Graphics Controller
The GLoria Synergy controller in Compaq Professional Workstation 5100 comes standard with 8
MB of SGRAM memory to provide greater color depth in higher resolution modes. Unified
2D/3D graphics controllers available for the Compaq Professional Workstation provide
exceptional performance at a low cost. Professionals who require fast window and menu level
performance as well as robust 3D rendering capabilities use 2D/3D graphics. The 2D performance
of these solutions is competitive with 2D only controllers such as the Matrox Millennium II.
Requirements for the 2D/3D graphics segment include exceptional 2D/3D-vector performance,
3D shading and lighting, and some texture mapping support. These features used by mainstream
OpenGL and Heidi based applications typically offer great price/performance without sacrificing
required functionality. This combination is important for mainstream CAD applications, such as
AutoCAD, Microstation, andSolidWorks that have recently integrated 3D techniques into their
environment. It is also useful in DCC where 2D and 3D animation applications are used in the
same environment. Financial analysis and trading environments can benefit from the 2D
performance provided by these solutions. Graphics controllers in this segment also provide
investment protection as financial analysis application developers add 3D modeling to their
environment in FY98.
A low-cost / high-performance leader in this area is the ELSA GLoria Synergy. This controller is
based on the new Permedia-2 graphics engine from 3Dlabs. It provides the 2D performance of a
Matrox Millennium II while adding a robust 3D environment that rivals the performance of
previous GLINT Delta/TX boards, such as the GLoria-L. The GLoria Synergy is the perfect low-
cost solution for mainstream CAD, web authoring, pre-print, and 2D/3D animation applications
that don’t require greater than 1280x1024 resolution for true-color rendering.
ELSA GLoria Synergy Features
♦Provides 2D windowing performance equivalent to the Matrox Millennium II
♦A low-cost solution for professional 3D applications, such as AutoCAD, Microstation,
SolidWorks, and 3D Studio Max
♦Supports a wide range of resolutions and color depths for flexibility and performance in a
variety of 3D graphics environments
♦Supports up to 4 displays using multiple controllers (depending on slot availability)
♦Uses 3Dlabs Permedia 2 processor for highly integrated 2D and robust 3D rendering
requirements
♦Comes standard with 8MB of SGRAM
♦Supports a wide range of resolutions (up to 1600 x 1280) and color depths for flexibility and
performance in a variety of 3D graphics environments

ELSA GLoria-XL 3D Graphics Controller
Select models of the Compaq Professional Workstation 5100 include the GLoria-XL 3D graphics
controller to deliver high resolutions and color depths for customers running a variety of 2D and
3D applications. This is a new 3D controller based on the 3Dlabs MX + Delta graphics
processors.
The ELSA GLoria-XL 3D graphics controller provides an optimized hardware pipeline for
acceleration of floating-point intensive 3D graphics including hardware support for texture
mapping, which is required by certain applications in the CAD/CAM and animation arenas.
The GLoria-XL uses dual-ported Video RAM (VRAM) for the frame buffer. The GLINT
processor used on the GLoria-XL also has a separate DRAM-based Z-buffer for Z-coordinates
(the third dimension in 3D), alpha data (transparency and fog effects), stencil buffer, and texture
maps. The GLoria-XL also incorporates the S3 Trio64V2 processor for VGA boot support, which
has its own dedicated DRAM-based frame buffer. The GLoria-XL also supports the new Compaq
P1610 24” monitor at resolutions up to 1920 x 1200. It is also capable of processing 16.7 million
colors in resolutions up to 1920 x 1080.
The GLoria-XL comes standard with 16 MB of VRAM frame buffer memory, 24 MB of DRAM
Z-buffer/texture memory for the GLINT processor, and 1 MB DRAM Frame Buffer memory for
the S3 Trio64V2 VGA processor. The Z-buffer/texture memory is upgradeable up to 40 MB
DRAM to provide greater Z-buffer and alpha depth in higher resolution modes, and texture-
mapping memory. Compaq offers a 16 MB z-buffer/texture memory upgrade option. The
maximum resolutions, colors, and refresh rates are outlined in the chart below; lower resolutions
are selectable.

GLoria-XL Features
Features of the GLoria-XL 3D graphics controller include:
•Support for major industry 3D APIs, including
•OpenGL – Open Graphics Library is a software interface to graphics hardware developed
by Silicon Graphics Inc.
•Direct3D – A set of APIs for real-time 3D graphics that are an addition to the Microsoft
DirectX interactive media technologies. They provide a comprehensive 3D solution for
software developers building interactive media programs and games
•Heidi – 3D API fromKinetix (an AutoDesk company) that provides an immediate 2D
and 3D mode drawing interface for 3D Studio Max.
•Display list drivers – Provide performance acceleration for AutoCAD R13 and
Microstation.
•On-board VGA support with S3 Trio64V2 chip for full-screen DOS box support on
Windows NT Workstation 3.51 and 4.0.
•GLoria Setting, an applet that allows the user to optimize the performance of the GLoria-XL
for a specific application with the click of a button. This applet automatically optimizes the
GLoria-XL for a specified application by changing the driver parameters to values that
“Tune” it for that application. All users have to do is select their program from a list that is
provided. The supported applications include Pro/E, AutoCAD, SoftImage, and 3Dstudio
Max.
•Hardware accelerated 3D, 32-bit z-buffering for realistic depth perception and texture
mapping.
•Full, 32-bit double buffering for smooth animation by allowing the next image to be created
in off-screen memory while displaying the current image.
•Gouraud shading for smooth surfaces.
•Texture mapping for creating realistic images.
•Fog for fading effects, atmospheric effects, anddepth-queuing.
•Anti-aliasing to provide smooth colors for rendered scenes by blending the colors of
neighboring pixels.
•Alpha-blending for creating transparent effects such as an object behind a window.
•1 millionGouraud-shaded, depth-buffered, 25-pixel triangles per second with 32-bit color,
32-bit Z-buffer, dithering, stenciling, clipping, and fogging enabled.
Bi-linear texture
filtering: a technique
used to improve the
ability to scale 3D
graphics, especially
texture maps. Bilinear
texture filtering
averages the four
adjacent texels (texture
map element) or
interpolates, thus
creating a newtexel.
Mip-mapping: a
texture map is stored at
several levels of detail
in a structure called a
mip-map. Tri-linear
mip-mapping uses a
more complex
interpolation technique
thanbi-linear filtering -
resulting in a more
realistic rendering used
for landscapesand
motion.

3D-RAM is a new technology used for the Frame buffer and Z-buffer memory on the Fire GL.
This design includes a small arithmetic logic unit in the DRAM that performs a number of the
calculations locally. This improves performance by reducing traffic to and from memory.
The Fire GL uses CDRAM (Cache DRAM) for the texture memory. This technology provides a
small SRAM cache built into the DRAM. This high-speed cache provides a buffer for texture
between the controller and the DRAM memory, which reduces data access times and ultimately,
increase graphics performance.
With all of the Fire GL’s high performance features, it can deliver performance exceeding the
throughput capabilities of the PCI bus. One component of the Highly Parallel System Architecture
in the Compaq Professional Workstation 6000 and 8000 is dual peer-PCI buses, which eliminates
the potential PCI bus bottleneck to provide improved throughput and overall system performance
when compared to single bus implementations.
The Fire GL 4000 comes standard with 15 MB of 3D-RAM for frame buffer and Z-buffer
memory, 16MB of CDRAM for texture memory, and 1 MB DRAM Frame Buffer memory for the
CIRRUS Logic 5446 VGA controller. The maximum resolutions, colors, and refresh rates are
outlined in the chart below; other resolutions are selectable:

mastering interface between the PCI bus and SCSI devices. Wide-Ultra SCSI is the latest SCSI
technology, replacing previous Fast-SCSI-2 and Narrow-Ultra SCSI versions. Wide-Ultra SCSI
provides a 16-bit bus master interface capable of data transfer rates up to 40 MB per second. A
total of seven SCSI devices can be connected to the internal or external SCSI connector.
Examples of SCSI devices include harddrives, CD-ROM drives, scanners, tape backups, and
removable media drives. The driver for this controller is the same one that is used with the
Compaq Professional Workstation family and Compaq server products. SmartStart for
Workstations installs this driver for the customer during set-up.
