Abstract: A method includes, in response to receiving an instruction to perform a first operation on first data stored in a memory device, obtaining first compression metadata from the memory device based on an address for the first data, and reducing a number of operations in a set of operations based on the first operation and one or more matching addresses, the one or more matching addresses corresponding to second compression metadata matching the first compression metadata.

Abstract: A method of operating a cache in a computing device includes, in response to receiving a memory access request at the cache, determining compressibility of data specified by the request, selecting in the cache a destination portion for storing the data based on the compressibility of the data and a persistent fault history of the destination portion, and storing a compressed copy of the data in a non-faulted subportion of the destination portion, wherein the persistent fault history indicates that the non-faulted subportion excludes any persistent faults.

Abstract: Systems, methods, devices, and computer-implemented instructions for processor power management implemented in a compiler. In some implementations, a characteristic of code is determined. An instruction based on the determined characteristic is inserted into the code. The code and inserted instruction are compiled to generate compiled code. The compiled code is output.
