Design of a 16-Bit Harvard Structured Risc Processor using Cadence 45nm Technology
The architecture of a MIPS (Microprocessor without Interlocked Pipeline Stages) based RISC or Reduced
Instruction Set of Computers is a type of microprocessor which was designed by Harvard type data path structure to execute
high speed using a small set of Instructions. This project explains the design and implementation of a 4-stage pipelining
based low power processor. This feature leads to increase the reliability and speed of the system. The pipelining includes
fetch, decode, execute and memory read/write operations. Low power was obtained by using clock gating technique. Clock
gating is used to eliminate the unwanted clock usage when the module is not used. The main aim of the project is to design a
4-stage pipelined RISC processor starting from RTL to GDSII (Physical Design). The processor was coded by Verilog HDL
language and implemented in Cadence Encounter Compiler tool. Calculated area, power, delay and clock gating using
Cadence RTL compiler using slow and fast libraries of 45nm technology.
