PrPMC750: MPC750 PowerPlus II Architecture Processor PMC
|
|
The PrPMC750 Processor PCI Mezzanine Card (PrPMC) creates a powerful new "macro component" that helps enable faster time to market, increases performance, and offers OEMs a standard module to easily customize and upgrade their designs. Traditionally, embedded computing architectures plug small mezzanine boards that hold specialized I/O interfaces into a motherboard or baseboard in order to adapt to the needs of a particular application. Today, complex applications require a reverse approach that places the microprocessor on the mezzanine card and all of the I/O interfaces on the baseboard. This simplifies product development and helps speed time to market by enabling OEMs to concentrate on designing and debugging their custom 33 MHz PCI logic, rather than devoting resources to designing and debugging high-speed memory, cache interfaces, and 350 MHz microprocessor logic. The PrPMC750 can serve as the primary- or host-microprocessor, which is connected to a baseboard full of PCI-based I/O interfaces. The PrPMC750, however, can also serve as an additional- or slave-microprocessor, creating a loosely coupled multiprocessing system. This new approach significantly expands design options for a broad range of applications. The PrPMC750 provides an MPC750 class microprocessor, L2 cache, ECC memory, Flash, timers and a debug port all on the familiar single-wide standard height PMC. |
