Abstract:
A computing element, system, and method for implementing control structures for a compressed cache in hardware. Embodiments provide a first engine configured to allocate and deallocate virtual memory pages and physical memory pages from pools of available pages to store received data to the compressed cache, a second engine configured to compress received data and store the compressed data. Embodiments also provide for embedding data within the virtual and physical memory pages to indicate page size, type, and data compression.
