基于解耦方法的可配置MIPS微处理器设计

Configurable MIPS Microprocessor Design Based on Decoupling Method

摘要: 传统固定功能微处理器的设计是为了满足通用应用的需求，因此可能无法充分适应特定领域或特定任务的要求，缺乏灵活性，所以在某些特定任务下，提供的不是最优的性能。针对该问题，本文设计了一种可配置的微处理器，通过模块解耦的方法选择是否添加CP0相关模块的微处理器架构，使该微处理器在是否可以实现异常指令、特权态指令两种架构中进行切换，并且可以优化资源利用、降低功耗和减少成本。同时，可以广泛地应用在使用轻量级微处理器的场景中。

Abstract: Traditional fixed-function microprocessors are designed to meet the needs of general-purpose ap-plications, so they may not be fully adapted to the requirements of specific domains or specific tasks, lack flexibility, and therefore provide suboptimal performance for some specific tasks. In order to solve this problem, this paper designs a configurable microprocessor, and selects whether to add the microprocessor architecture of CP0 related modules through the method of module decoupling, so that the microprocessor can switch between the two architectures of abnormal instructions and privileged instructions, and can optimize resource utilization, reduce power consumption and reduce cost. At the same time, it can be widely used in some scenarios using lightweight microprocessors.
