最开始这部分内容是分散在The RISC-V Instruction Set Manual Volume II: Privileged Architecture中的,后来把它单独拿出来了。可见官方的设计思路是不把aclic作为riscv内核的一部分,而是一个模块化的可定制组件,只要按照该规格书实现都可,方便模块化和自定义。这也是RISCV设计哲学的一个重要思想。之前是clint现在优化...
RISC-V (pronounced risk-five) is a new instruction set architecture (ISA) that was originally designed to support computer architecture research and education, but which we now hope will become a standard open architecture for industry implementations. The RISC-V manual is structured in two ...
