RISC processor implementation 32-bit MIPS-based: an approach to teaching and learning

Implementação do processador RISC baseado em MIPS de 32 bits: uma abordagem para o ensino e aprendizagem

Resumo

This article describes the development of the design of a processor based on the RISC architecture, taking the 32-bit MIPS microprocessor as a basis. The RISC architecture, which stands for Reduced Instruction Set Computer, is characterized by having a reduced instruction set, aiming to optimize the processor's overall performance. The designed MIPS processor follows a 5-stage pipeline, which comprises the instruction fetch, instruction decode, execution, preparation and memory access phases. The main objective of this article is to carry out the structural development of the processor, using the hardware description language. This implies the creation of a Verilog representation that will later be used to generate the extraction of the processor's logic circuit. Furthermore, the project involves generating a timing diagram that illustrates the temporal behavior of processor operations and, ultimately, the physical implementation of the processor core. This work seeks to contribute knowledge in the field of computer architecture, providing a practical implementation of a RISC processor based on the 32-bit MIPS architecture, which can be relevant both for educational purposes and for practical applications in embedded systems.
