DESCRIPTION:

The IDT7M9510/7M9514 is a Single Board Computer utilizing IDT's

79RV4640/79RC64V474 MIPS processor. This CPU Mezzanine Card is

designed for use in applications where low profile, parallel board to board

mounting is required. The 7M9510/7M9514 consists of an IDT79RV4640 /

IDT79RC64V474 processor based subsystem that can either form the core

CPU function for an embedded application, or can be an optional add-in

accelerator to a PCI based system through a PCI v2.1 compatible, PMC

Standard (IEEE P1386.1) connector.

The card conforms, in length and width to the standard single size PMC form

factor as specified in IEEE P1386.1, and it contains all the features required of

a typical CPU subsystem for embedded processor applications. Some of these

features include: DRAM, Flash, serial ports and full PCI interrupt support
