| Abstract(in English) | We have developed a 0.25-μm 200-MHz embedded RISC processor for multimedia applications. This processor has a dual-issue superscaler datapath of 2000-MOPS performance that consists of a 32-bit integer unit and a 64-bit SIMD function unit. An on-chip Concurrent Rambus DRAM(C-RDRAM)controller expands memory bandwitdh to 533 Mbyte/s through the Rambus channel using interleaved transactions. The controller also reduces latency 9% and 70% using the transaction interleaving and instruction prefetching, respectively. A 64-bit 200-MHz internal bus transmits the data between the CPU core, the C-RDRAM, and the peripherals. These high-data-rate channels increase the performance of the CPU because they eliminate a bottleneck in the data supply. |
