摘要:
An embodiment of an integrated circuit may comprise, coupled to a core, hardware decompression accelerators, a compressed cache, a processor communicatively coupled to the hardware decompression accelerators and the compressed cache, and memory communicatively coupled to the processor, wherein the memory stores microcode instructions that when executed by the processor causes the processor to load a page table entry in response to an indication of a page fault, determine if the page table entry indicates that the page is to be decompressed on fault, and, if so determined, modify a first decompression work descriptor at a first address and a second decompression work descriptor at a second address based on information from the page table entry, and generate a first enqueue transaction to the hardware decompression accelerators with the first address of the first decompression work descriptor and a second enqueue transaction to the hardware decompression accelerators with the second address of the second decompression work descriptor. Other embodiments are disclosed and claimed.
