Product Overview
VMP1
PEP’s V ME PowerPC Processor
board with Floating point unit
based on the MPC8240 is a
straight forward computing
design.
CPU, Memory and DMA
The VMP1 is a comprehensive
computing platform realized as a lean
CPU design with only those functions
required for basic industrial
calculation tasks.It addresses the need
for increasing computing capacity
while reducing the number of system
components and taking up less space.
Based on the MPC8240, a highly
integrated microprocessor containing
a PowerPC MPC603e core,two
different clock versions,200 MHz and
266 MHz,both with an FPU unit will
be initially available.
Anticipating the VMP1's use in data
critical applications,the memory data
path contains a selectable in-line ECC
controller which can provide SDRAM
single bit error correct or double bit
error detect.
For mass data transmission a dual
channel DMA controller is provided.
It can be programmed directly or
through the use of descriptor chains
located in memory.Data can thus be
moved from PCI to memory or vice
versa,memory to memory,or PCI to
PCI.
PCI bus and PCI Expansion
capability
PCI is used as the local bus to connect
the MPC8240 with the Fast Ethernet
controller and the PCI/VME bridge.
Moreover,it is routed to a 100 pin PCI
expansion connector that can be used
to add further functionality to the
VMP1.One or two VMP1-IO modules
can be plugged together with the
VMP1 (e.g.two PMC slots can be
added) resulting in a total package of
either 8HP or 12HP
V ME interface
The VMEbus interface (Universe 2)
delivers beside all functionality that is
needed by a VME CPU:
– automatic First-Slot-Detection
– integral FIFO buffers for multiple
transactions in both directions
– programmable DMA controller with
linked list support.
LA N
The i82559 10/100 Mbps Fast
Ethernet controller with an integrated
10/100 Mbps physical layer device is
the foremost solution for PCI board
LAN designs.It combines a low power
consumption with a small package
design which is ideal for power and
space constrained environments.
Serial ports
Two RS232 serial ports are realized
with the 16C2550 UART and supports
baud rates up to 1.5Mbps.
Support
One of the prime advantages of
utilizing the existing,time-tested,and
proven MPC603e core is the legacy
and infrastructure of support that
currently exists. All notable third-
party software tool vendors presently
endorsing the PowerPC architecture
have announced tools also for the
MPC8240.It supports processor
control and visibility through the
JTAG/COP (common on-chip
processor) interface that is accessible
on VMP1.Utilizing third party tools,
the developer can access and control
the processor.It also has standard
IEEE 1149.1a-1993 compliant
boundary scan capability.The ECC
data path has a mechanism to
manually inject errors into memory

for use with maintenance and
diagnostic utilities.Further a watch
point and capture register on the
internal bus as well as a set of address
attributes on the external memory
and PCI buses aid in debugging
analysis.
Universal Boot Loader
The VMP1 employs an operating
system independent boot loader that
enables the loading of any OS.This
boot loader makes an update of the
Flash contents and accomplishes an
automatic download from Flash to
SDRAM before booting the OS.For
high performance reasons the OS is
started from the SDRAM.
