instruction and the data will affect each other. Because directives and data are generally stored in different areas of memory, they are local in nature. With the execution of a program to manipulate a large amount of data, the data will quickly fill the cache, the instructions are squeezed out, at this time, the execution of an instruction, referring to the stage is likely to be a cache miss, need to wait for access to memory, it takes a long time. And in the execution phase, to fetch the oper
