Design and Analysis of A 32-bit Pipelined MIPS Risc Processor

Abstract

Pipelining is a technique that exploits parallelism, among the instructions in a sequential instruction stream to get increased throughput, and it lessens the total time to complete the work.. The major objective of this architecture is to design a low power high performance structure which fulfils all the requirements of the design. The critical factors like power, frequency, area, propagation delay are analysed using Spartan 3E XC3E 1600e device with Xilinx tool. In this paper, the 32-bit MIPS RISC processor is used in 6-stage pipelining to optimize the critical performance factors. The fundamental functional blocks of the processor include Input/Output blocks, configurable logic blocks, Block RAM, and Digital clock Manager and each block permits to connect to multiple sources for the routing. The Auxiliary units enhance the performance of the processor. The comparative study elevates the designed model in terms of Area, Power and Frequency. MATLAB2D/3D graphs represents the relationship among various parameters of this pipelining. In this pipeline model, it consumes very less power (0.129 W),path delay (11.180 ns) and low LUT utilization (421). Similarly, the proposed model achieves better frequency increase (285.583 Mhz.), which obtained better results compared to other models.
