Pipelined MIPS processor with cache controller using VHDL implementation for educational purposes

Abstract

This research adopts the VHDL (Very high speed IC Hardware Description Language) design of a direct mapped cache controller for a pipelined MIPS (Microprocessor without Interlocked Pipeline Stages) processor. In this design, the instruction cache and data cache are separated and located in the CPU (Central Processing Unit) core. Write back policy is used while no replacement algorithm is required. After completing the cache controller design, it is combined with a pipelined MIPS processor and used in programs execution. These designs are synthesized using (Xilinx ISE Design Suite 13.4) and simulated using (Xilinx ISim simulator).
