Device Overview

The RC32434 is a member of the IDT™ Interprise™ family of PCI

integrated communications processors. It incorporates a high performance

CPU core and a number of on-chip peripherals. The integrated

processor is designed to transfer information from I/O modules to main

memory with minimal CPU intervention, using a highly sophisticated

direct memory access (DMA) engine. All data transfers through the

RC32434 are achieved by writing data from an on-chip I/O peripheral to

main memory and then out to another I/O module.
