Specification
 Specification Details
1.2.1 CPU Kernel
The CPU kernel consists of the PowerPC 755 CPU with a clock rate
of 300 MHz and host bus clock of 66/83 MHz. The CPU contains
two parallel 32-bit integer execution units with an additional floating
point unit for 8 SPECint95 and 6.2 SPECfp95 at 200 MHz. It has an
external second-level cache running at 150 MHz. Memory is
controlled by the host bridge MPC106 which contains the bridge
between host bus and on-board PCI itself as well as the memory
interface for EDO or SDRAM modules in SODIMM format (144-pin
SODIMM module; 64-bit data bus). Memory size can be anywhere
between 8 and 128 MB, depending on the DIMM modules used.
1.2.2 Flash Memory
Up to 2 MB of user flash memory are supplied for storing user-
generated programs. Thus, diskless systems can be built.
1.2.3 PCI Devices
The board-internal PCI bus is used for all I/O devices as well as the
PCI-to-cPCI bridge. The PCI bus is of the master/slave type, capable
of DMA transfers as source and target.
A single-size PMC slot allows for interfacing, e.g. using a VGA
display adapter PMC module or a frame grabber interface. Due to the
bus-master DMA capabilities of the PMC implementation of the PCI
standard, frame grabber can be implemented efficiently without
frame buffers.
A optional PMC carrier board allows additional three PMC modules.

User’s Manual Specification
BAB 750 1—3
Specification
An Ethernet controller for either 10 Mbps or 100 Mbps Ethernet with
PCI DMA capabilities is provided on-board. Front panel interface is
10/100BaseT.
A optional ultra wide SCSI controller (53C875) allows transfer rates
of up to 40Mb/s.
The last interface on the local PCI bus is the ISA bridge (Winbond
W83C553), interfacing to the internal ISA bus with additional on-
board components. Additionally, there are the standard PC
components real-time clock, watchdog, keyboard controller, dual
serial I/O, floppy controller, IDE controller, and parallel controller.
1.2.4 CompactPCI Interface
A Intel 51152 32-bit PCI-to-PCI bridge is used to connect to the
compactPCI bus. The BAB 750 supplies system slot capabilities for
four other compactPCI boards.
1.2.5 PMC
A PCI extension card for PMC boards is provided. A PMC module
carrier board (PMCC) can be installed to provide three PMC module
slots. The PMC connectors are buffered with an additional 32-bit
PCI-PCI brdge device, located on the carrier board.
1.2.6 Mechanical
The board format is double Eurocard (6HU). If the optional PMC
carrier is used the BAB 750 requires two slots.
1.2.7 I/O
16-bit SCSI, floppy, IDE, keyboard, mouse, COM2, and speaker are
routed over the compactPCI P5 connector. Additionally printer and
PMC I/O is connected to compactPCI P4.

Specification User’s Manual
BAB 750
1—4
Specification
On the front panel the Ethernet 10BaseT connector is located as well
as the separate front panel for PMC I/O signals. The keyboard/mouse
connector and two serial RS232 channel are also routed to the front
panel.
1.2.8 Compatibility
The BAB 750 has been designed to be software-compatible to the
PowerPC reference platform (“Yellowknife”) as much as possible.
1.2.9 Related Documents

facturer's description of the PowerPC itself and the assembly
