Overview
The EPC-9 is a highly integrated PC-compatible computer designed for use in the
VMEbus and has VXIbus (VMEbus Extensions for Instrumentation) extensions, with
interfaces to the PCIbus and EXMbus. It is a two-slot 6U VMEbus module, with
support for two PCI Mezzanine Cards (PMC). It is compatible with all major PC
software environments, including Microsoft DOS, Microsoft Windows NT, and IBM
OS/2, plus others.
The PC-compatible portion of the architecture includes the following PC-standard
features:
• Intel Pentium 100, 133, 166, or 200 MHz processors.
• 256 KB secondary (L2) cache (512KB optional).
• 8, 16, 32, 64, 128, or 256MB of memory, using dual socket SODIMM DRAM.
• Standard front panel PC peripheral interfaces include two RS232 serial ports, an
IEEE-1284 bi-directional parallel port, two USB ports, a PCI-based SCSI-2
interface, and 10BASE-T/100BASE-TX Ethernet ports, all with standard
interface connectors. The mouse and keyboard connectors are PS/2 style.
• All other standard PC architectural features, including an onboard speaker.
• Two RadiSys PMC sites for add-on devices such as SVGA graphics, video
capture, or network interfaces.
• RadiSys standard EXM expansion interface for adding PC-architecture
peripherals or interfaces.
• Phoenix NuBIOS with RadiSys enhancements to support the additional onboard
features and VMEbus environment.

Additional features (some optional) include:
• SVGA interface. This PCIbus interface is based on the Cirrus Logic GD5446
chip, with up to 2MB of video RAM providing local bus graphics performance
and resolutions up to 1280x1024, with 64K colors. The standard
15-pin connector for this port is enhanced with a programmable output on pin 15,
which is not connected on a standard VGA interface.
• 10BASE-T and 100BASE-TX Ethernet interfaces. The interface is based on the
Digital 21143 Ethernet controller. Interface configuration (emulation mode and
address/interrupt control) is software controlled.
• A watchdog timer. This device can be configured to generate a VMEbus
SYSFAIL signal and either halt or perform a warm reboot of the processor,
depending on a BIOS setup option. The timer is implemented as a software-
retriggerable one-shot, with a programmable reset interval ranging from 128 ms
to 8.2 sec.

VMEbus
The VMEbus is controlled by the Tundra Universe VME/PCI Bridge chip with
enhancements for multiprocessor environments. This is described in the next three
sections, covering system controller functions, the VMEbus master interface, and the
VMEbus extended register set.
System controller functions
The Tundra Universe VME/PCI Bridge allows the EPC-9 to provide full VME slot-1
arbitration functions. When enabled, these functions include priority and round-robin
bus arbitration, IACK and bus grant daisy-chain driving, SYSRESET and SYSCLK
generation and bus time-out detection. ROR (release-on-request) or a fair-requester,
RONR (release-on-no-request) bus release mechanism is software selectable.
VMEbus master interface
The VMEbus master interface provides a full 32-bit data path to the 16, 24, and 32-bit
address spaces of the VMEbus. The bus interface is designed with a minimum
number of state registers, which maximizes performance in a multitasking or interrupt
driven environment.
Programmable hardware byte-swapping is provided for ease of communication with
other processor architectures that may share the VMEbus. All the VMEbus address
spaces can be addressed from both protected-mode and real-mode operating systems.
The EPC-9 can generate or respond to all 7 standard VMEbus interrupts, and can also
receive the VMEbus signals ACFAIL, BERR, and SYSFAIL as interrupts. The EPC-9
implements 16-bit IACK cycles when it generates interrupts.
VMEbus extended register set
As an extension to the VMEbus interface, the EPC-9 implements the set of VXIbus
(IEEE 1155-1992) standard multiprocessor support registers in the A16 space.
These registers provide a set of standard identification, status, control and
communication functions that are useful in multiprocessor environments. They allow
dynamic system configuration by providing for board identification, and provide well-
defined multi-processor communications channels and protocols.

The EPC-9 includes a complete set of VXIbus-defined message-based device
registers. These registers are implemented in a proprietary gate array and mapped into
the VMEbus A16 address space and include a device-type identifier register, bus
status and control registers, and a register-based message passing facility.
