SD812F 3BDH000014R1 Learn about the cache Compensate processor
Cache performance measurements become important in an era when the speed gap between memory performance and processor performance is growing exponentially. Caching was introduced to reduce this speed gap. Therefore, understanding the cache's ability to bridge the processor and memory speed gap becomes important, especially in high-performance systems. The cache hit ratio and cache miss ratio play an important role in determining this performance. In order to improve the performance of cache, reducing the miss hit ratio becomes one of the necessary steps. Reducing access time to the cache also helps improve its performance.
CPU stop
The time it takes to get a cache line out of memory (read latent due to cache misses) is important because the CPU will have nothing to do while waiting for the cache line. When a CPU reaches this state, it is called a standstill. As the CPU becomes faster than main memory, pauses due to cache misses replace more potential computation; Modern cpus can execute hundreds of instructions in the time it takes to extract a cache line from main memory.
During this time, various techniques were employed to keep the CPU busy, including out-of-order execution in which the CPU tries to execute separate instructions after waiting for the instruction to cache the missed data. Another technique used by many processors is simultaneous multithreading (SMT), which allows another thread to use the CPU core while the first thread waits for the required CPU resources to become available.
