Abstract
Aspects disclosed relate to a priority-based access of compressed memory lines in a processor-based system. In an aspect, a memory access device in the processor-based system receives a read access request for memory. If the read access request is higher priority, the memory access device uses the logical memory address of the read access request as the physical memory address to access the compressed memory line. However, if the read access request is lower priority, the memory access device translates the logical memory address of the read access request into one or more physical memory addresses in memory space left by the compression of higher priority lines. In this manner, the efficiency of higher priority compressed memory accesses is improved by removing a level of indirection otherwise required to find and access compressed memory lines.
