Modeling a microprocessor with RISC architecture

Microprocessors with RISC architecture are widely used in various fields, including mobile devices, embedded systems, and high-performance computing. They are an essential component of computer systems. The selection of a suitable microprocessor architecture is required in the automated design and implementation of various computer configurations. This makes the development of various computer models of microprocessors relevant.RISC (Reduced Instruction Set Computer) is an architectural approach to processor design that is characterized by the use of a small set of simple and fast instructions. The main idea behind this approach is to simplify the processor hardware, allowing more instructions to be executed in less time. Microprocessors with RISC architectures are optimized for performance by:•Use of fixed instruction length.•Maintaining a large set of registers for fast data access.•Avoidance of complex operations and instructions that execute slowly.•Using techniques such as pipelining to improve efficiency.In this report, the developed Verilog model of a microprocessor with RISC architecture is presented. A description of the modeled architecture and the Verilog models of its building blocks is made. The Vivado development environment and its built-in visual simulation tools were used for model validation.Verilog is a hardware description language. It allows the description of the structure and behavior of digital systems at different levels of abstraction: logical, behavioral and register level. This makes it a convenient and appropriate tool in the process of designing and verifying integrated circuits, as well as computer system components.
