Preface: The first-level (L1) cache is small enough to provide a one- or two-cycle access time. The second-level (L2) cache is also built from SRAM but is larger, and therefore slower, than the L1 cache. The processor first looks for the data in the L1 cache. If the L1 cache misses, the processor looks in…

 (1st Sep 2023) Preface: AI (Artificial intelligence) moves from big data normalization to learning to understand data, so called trained. It require large amount of computer processing resources. The machine learning process requires CPUs and GPUs. GPUs are used to train large deep learning models, while CPUs are good for data preparation, feature extraction, and…
