2. 拿ARM来说,(其ISA是ARMv7等)其微体系结构是ARM11等从11往后叫cortex系列,其中cortex-A系列有32位的A7、A9、A15,64位的A53、A57。 3. 指令集(Instruction set) 3.1 定义 通常会把CPU的扩展指令集称为”CPU的指令集”(因为基本的,类似加减的指令似乎是必须被CPU所支持的指令)。每款CPU在设计时就规定了...
二级缓存相比一级缓存要大些，有256K，但是不分Data和Instruction。另外L2和L1一样，也是总共有12个，...
The instruction set is just a collection of methods that when called know which electrical circuits combination it need to use in order to achieve what was asked. In thises circuits there are few that are similar in both core but some only exist in CPU others in GPU so instruction set can...
two-way set associative cache:将地址mod8,存到对应的2个entry中的任何一个 -> 你存好了数据,下面就要开始继续读写了 假如要读一个数据,发现没被存到cache里且cache满了,要丢哪个已经存的数据呢? 就涉及到replacement policy,比如说LRU(用double linked list实现?)之类的 假如要写一个数据,这个数据所在地址...

1 GNU 汇编格式 label:instruction @ comment label 即标号,表示地址位置,有些指令前面可能会有标号,这样就可以通过这个标号得到指令的地址,标号也可以用来表示数据地址。注意 label 后面的“:”,任何以“:”结尾的标识符都会被识别为一个标号。 instruct
