Specification Details
1.2.1 CPU Kernel
The CPU kernel consists of the PowerPC-740 CPU with clock rates
of 266 MHz and host bus clocks of 66 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 (2-1-1- 1 clocks) and main memory
attached directly to the CPU’s host bus. 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 SO DIMM format (144-pin SO DIMM
modules; 64-bit data bus). Memory size can be anywhere between 8
and 128 MB, depending on the DIMM modules used. Two sockets
can be equipped with SO DIMM modules but the board is also
running with only one module.
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-VME bridge. The PCI bus is of the master/slave type, capable
of DMA transfers as source and target.
Two single-size PMC slots allow for flexible interfacing, e.g. using a
VGA display adapter PMC module and additionally 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.
