Emerson’s PmPPC440 is a complete low-power processor subsystem in a very compact, industry standard form factor. It is designed to allow communication equipment manufacturers to add modular and upgradable compute functionality to their I/O baseboard and provide the localized horsepower necessary for applications such as protocol processing, packet processing, data filtering or I/O management.
Using an off-the-shelf processor subsystem saves you time-to-market by allowing you to focus your engineering efforts on the key value-add portions of the system without spending time and effort on the processor design and testing. A modular processor subsystem also lowers your lifetime cost of ownership by providing an easy upgrade path, and protecting you from obsolescence issues.
Considerable engineering effort has gone into ensuring maximum flexibility on the PmPPC440. The module can be used in both Processor PMC Monarch and Non-Monarch modes, which means that it can act as the host (Monarch) of the local PCI bus or be a target (Non-Monarch) on the local PCI bus depending on the application or baseboard. We’ve also implemented the SDRAM memory using SODIMM packaging, the same memory package used dominantly in laptop computers.
