MIPS CPU architecture
The MIPS64 and microMIPS64 Privileged Resource Architecture (PRA) is a set of environments and capabilities on which the Instruction Set Architectures operate. The effects of some components of the PRA are user-visible, for instance, the virtual memory layout. Many other components are visible only to the operating system kernel and to systems programmers. The PRA provides the mechanisms necessary to manage the resources of the CPU: virtual memory, caches, exceptions and user contexts. This chapter describes these mechanisms.
