... IDT79R3041 INTEGRATED RISController FOR LOW COST SYSTEMS INTRODUCTION The IDT RISController family is a series of high-perfor- mance 32-bit microprocessors featuring a high-level of inte- gration, 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 sen- sitive applications ...

... IDT79R3041 INTEGRATED RISController FOR LOW COST SYSTEMS Clock Generation Unit The R3041 is driven from a single 2x frequency input clock, capable of operating in a range of 40%-60% duty cycle. On- chip, the clock generator unit is responsible for managing the interaction of the CPU core, caches, and bus interface. The clock generator unit replaces the external delay line required in R3000A based applications ...

... IDT79R3041 INTEGRATED RISController FOR LOW COST SYSTEMS • Programmable memory Port Widths: The R3041 allows the kernel to partition the physical memory space into various sub-regions, and to individually indicate the port width of these sub-regions. Thus, the bus interface unit can perform data packing and unpacking when communicating with narrow memory sub-regions ...
