The ARM710 upgrade card for the Risc PC 600 is now available from Acorn Direct. The new card will give existing Risc PCs even more exceptional performance, particularly in high resolution graphics modes. The card is based on the ARM710 32-bit RISC processor clocked at 40MHz, (a 33% improvement over the existing Risc PC 600). In addition to the 8kB cache, the processor of the ARM710 includes on the same silicon an enhanced write buffer and a Memory Management Unit (MMU) with memory Translation Look Aside Buffer twice the size of the ARM610. These features increase the average execution speed and reduce the memory bandwidth required by the processor. This allows the external memory to support additional processors and Direct Memory Access (DMA) channels with minimal performance loss. The ARM710 processor is extremely energy efficient, consuming significantly less power in operation than other CPUs with similar performance. This has benefits in reliability and heat dispersal. Upgrading is simplicity itself, simply turn the power off, remove the lid, unplug the existing processor card, and plug in the new ARM710 card.
