The authors report on the design of efficient cache controller suitable for use in FPGA-based processors. Semiconductor memory which can operate at speeds comparable with the operation of the processor exists; it is not economical to provide all the main memory with very high speed semiconductor memory. The problem can be alleviated by introducing a small block of high speed memory called a cache between the main memory and the processor. Set-associative mapping compromise between a fully associative cache and a direct mapped cache, as it increases speed.
