Abstract
Aspects include computing devices, systems, and methods for implementing a cache memory access requests for data smaller than a cache line and eliminating overfetching from a main memory by combining the data with padding data of a size of a difference between a size of a cache line and the data. A processor may determine whether the data, uncompressed or compressed, is smaller than a cache line using a size of the data or a compression ratio of the data. The processor may generate the padding data using constant data values or a pattern of data values. The processor may send a write cache memory access request for the combined data to a cache memory controller, which may write the combined data to a cache memory. The cache memory controller may send a write memory access request to a memory controller, which may write the combined data to a memory.
