Global management of cache hierarchies
Mohamed Zahran, Sally A. McKee · 2010
Cache memories currently treat all blocks as if they were equally important. This assumption of equally important blocks is not always valid. For instance, not all blocks deserve to be in L1 cache. We therefore propose globalized block placement. We present a global placement algorithm for managing blocks in a cache hierarchy by deciding where in the hierarchy an incoming block should be placed. Our technique makes decisions by adapting to access patterns of different blocks.
