微处理器中存储器管理的研究

Research of memory management unitin microprocessor

通过分析该微处理器访存的时序要求以及对存储器保护的要求,设计了具有自主知识产权的存储器管理部件,论述了逻辑地址映射到物理地址、存储块保护以及Cache设计思想。

The memory management unit is designed after analyzing the timing and protectingrequirements.The design thought for mapping virtual address space into physical address space,block protection unit and Cache are also discussed.
