CPU cache mechanisms.

CPU的缓存机制。

It's unfortunate, but keeping the CPUs busy makes up for the problem of a CPU cache being cold for a migrated task.

不幸的是，保持CPU繁忙会出现CPU缓存对于迁移过来的任务为冷的情况。

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.

在基于冯诺依曼架构的计算机中（没有CPU缓存），CPU或者从存储器中读取指令或数据，或者在存储器中写入数据。

Of course, the exploit that they've actually released is completely harmless, but it demonstrates that the CPU cache can be "poisoned" to let folks read and write into the otherwise protected SMRAM memory.
