Advances in Microprocessor Cache Architectures Over the Last 25 Years

Over the last 25 years, the use of caches has advanced significantly in mainstream microprocessors to address the memory wall challenge. As we transformed microprocessors from single-core to multicore to manycore, innovations in the architecture, design, and management of on-die cache hierarchy were critical to enabling scaling in performance and efficiency. In addition, at the system level, as in...
