这也就回答了为什么我们需要硬件提供cache coherence的支持,因为cache coherence是作为synchronization(CPU原子指令来实现)的building block。对于最早的原子指令设计是通过bus lock来实现的,但是性能开销太大,硬件提供的cache coherence保证可以大大提升原子指令的效率,因此现代CPU的原子指令大都是基于cache coherence的,少量的...
In contemporary multiprocessor systems, it is customary to have one or two levels of cache associated with each processor. This organization is essential to achieve reasonable performance. It does, however, create a problem known as the cache coherence problem. The essence of the problem is this:...

The shared L2 cache is maintained by MOESI_CMP_directory coherence protocol from Gem5 simulator [7], and write back strategy is employed. In order to explain architecture setups well, we make five key assumptions as follows: • The shared cache is partitioned into several bank groups while ...
