Abstract: A processor for optimizing partial writes to compressed blocks is configured to identify that a write request targets less than an entirety of a compressed block of pixel data, identify, based on a compression key, a compressed segment of the compressed block of pixel data that includes a target of the write request, and decompress, responsive to the write request, only the identified compressed segment of the compressed block of pixel data.
