也正因为如此,造成了VA1和VA2寻址的cache的index不同,被放到不同的cache set上,这时候问题就出现了:cache中两个不同位置对应着物理存储器中同一个物理地址,这样不但造成了cache空间的浪费,而且当cache的VA2对应的数据改变时,VA1的数据不会变化,因此造成了一个物理地址在cache中有两个不同值的问题,当后续load...

RISC stands for Reduced Instruction Set Computer – this typically refers to architectures which use significantly fewer complex instruction types than CISC architectures (Complex Instruction Set Computers). CISC architectures typically consist of highly varied instruction sets ranging from simple arithmetic op...
2-6、6502的指令(instruction)。 (从10分06秒到12分06秒) 6502CPU有56条设定的指令(legal instructions),我会在后面解释它们的用途。这56条指令会随着参数(argument)的变化而修改指令的大小和持续时间,幸运的是,我们可以根据指令第1个字节的名称,获得我们需要的信息,然后准确的模拟出这56个指令。 图片(指令的第...
