[email protected] It had been found that when a processor talks to the memory the speed gets killed. In a single, purpose processor (with a stable, well-defined operation set), a direct-execution CISC design would make sense because the "library" of code is so small that hardwiring it (not merely placing it in ROM for a microcode implementation, though such would also be more efficient that a RISC design, it seems) would increase speed. The RISC processor is designed based on its instruction set and Harvard-type data path structure. 13053/CyS-19-2-1941 Design of a General Purpose 8­bit RISC Processor for Computer Architecture Learning 373 ISSN 2007-9737. 16- Bit RISC Processor Design for Convolution Application Using Verilog HDL.
