Features:
- Four Freescale MPC7410 G4 PowerPC Processors
- Floating-Point AltiVec Vector Processing Engine
- 400/500 MHz Clock Speed
The Pentek 4295 Series Quad MPC7410 PowerPC Processors PMC/VIM - VME targets embedded applications requiring
high-performance interfaces. Featuring
four Freescale MPC7410's, the 4295
supports numerous high-speed interfaces
including VIM, PMC, RACEway, VME64
and Ethernet.
As one of the G4 RISC processors in the
PowerPC family, the Freescale MPC7410
utilizes the AltiVec vector engine to perform
parallel processing of multiple data elements
(SIMD) with 128-bit operations. The AltiVec
processor executes both fixed- and floating-point
instructions, augmenting the separate
integer and floating-point units on the chip.
Four processor nodes contain interface
and memory resources ideally matching
the raw processing power of the MPC7410
to the I/O demands of high-performance
system components.
Each of the four nodes includes local
memory and access to shared global
resources and interfaces.
Two processors are equipped with their
own VIM (Velocity Interface Mezzanine)
connector, providing a private high-speed
synchronous bidirectional FIFO (BI-FIFO)
which buffers 32-bit parallel data transfers
between the mezzanine module and the
MPC7410. The VIM architecture allows
simultaneous I/O data transfers to both
processors with no contention for shared
resources. Control and status registers on
the VIM modules can be read and written
to as memory mapped resources of the
MPC7410. Dual serial ports provide an
additional data streaming connection
between each processor node and its associated
VIM module.
In addition to accommodating Pentek's
broad range of VIM I/O peripherals,
4295 incorporates a PCI Mezzanine Card
(PMC) module site, which accepts industry standard
modules for a wide variety of
interface and communication functions.
The PMC module is accessible from all four
MPC7410's and from the VMEbus.
Three types of local memory resources
are provided for each MPC7410: a fast 2 MB
level 2 cache, a large 32 MB SDRAM (128 MB
OEM optional), and a nonvolatile 4 MB FLASH
memory for initialization, self-test and boot
code.
The 4295 architecture includes a
PCI bridge and SDRAM memory controller
that also includes a powerful DMA engine
useful for moving data between resources
on the board. Two of the three 64-bit PCI
buses on the 4295 are connected to this
device. One PCI bus provides access from
each of the four processor node controllers
to global SDRAM, global FLASH memory,
an RS-232 serial port and other global resources
located on the second PCI bus.
This bus features interfaces for VMEbus,
Ethernet, a second RS-232 port and
RACEway.
An additional 64-bit PCI bus provides
dedicated interprocessor communication
as well as a path to the PMC site. This creates
a path between processors or processors and
a PMC module, allowing data transfers of
up to 528 MB/sec, independent of all other
board resources.
Each MPC7410 can master both PCI
buses for read/write access to each
SDRAM memory in all four processor
nodes, Ethernet, RS-232, RACEway, and
VMEbus.
All four MPC7410s can master the
VMEbus using the industry standard Universe
II VME64 interface chip. As a VMEbus
slave, the 4295 presents all four
processor node SDRAM memories for
convenient read/write access from any
VMEbus master.
The PC.6829002G Pentek Daughter Card may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
