INTRODUCTION
The IDT RISController family is a series of high-performance 32-bit microprocessors featuring a high-level of integration, and targeted to high-performance but cost sensitive embedded processing applications. The RISController family is designed to bring the high-performance inherent in the MIPS RISC architecture into low-cost, simplified, power sensitive applications.
