• If the data or instruction is not present in the cache, or if the cache line is invalidated, the CPU updates its cache by reading the data from the main memory.

    如果数据指令没有出现高速缓存中,或者如果高速缓存线路无效的时候,CPU通过存储器中数据来更新的高速缓存。

  • Neither a memory management unit nor an instruction or data cache are used.

    这既不需要使用内存管理单元也不需要使用指令数据缓存

    youdao

  • In a computer with the contrasting von Neumann architecture (and no CPU cache), the CPU can be either reading an instruction or reading/writing data fROM/to the memory.

    基于冯诺依曼架构计算机中(没有CPU缓存),CPU或者存储器中读取指令数据或者在存储器中写入数据。

    youdao

  • In a computer using the Harvard architecture, the CPU can both read an instruction and perform a data memory access at the same time, even without a cache.

    使用哈佛架构计算机中,即使没有缓存CPU也可以读取指令同时进行数据访问
