1 [计]?指令存储器 ...需要的数据不在Cache 中,即缺失,空指令将 在Hit 置0 时通过选择器(mux)传给IF,同时Address 将传给指令存储器(Instruction memory),存储器将相 应地址的指令导入Cache 中,Cache 将按FIFO 算法对信息进行替换。 2 ?指令记忆体 指令记忆体 (Instruction Memory) 指令记忆体用于程式指令的储存。处理器会根据程 式计数器的内容(位址)读取相对应的记忆体资料,并 将指令送往 IF/ID 阶段暂存...
- 1
The address space corresponding to instruction memory is always indicated cacheable, which is correct in function. 在任何情况下指令存储器所对应的地址空间都是可缓存的。 - 2
In some systems, there is much more instruction memory than data memory so instruction addresses are wider than data addresses. 在一些系统中,指令存储器比数据存储器更大,所以指令地址的宽度要高达数据地址。 - 3
Its successor was the 4040 processor (released in 1974), which had an expanded instruction set, program memory, register set, and stack. 其后面是4040处理器(1974发布),其具有扩展指令集、程序内存、寄存器集和堆栈。
