PC.6829002G Pentek Daughter Card

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.
