Abstract
A computer system includes a cache and processor. The cache includes a plurality of data compartments configured to store data. The data compartments are arranged as a plurality of data rows and a plurality of data columns. Each data row is defined by an addressable index. The processor is in signal communication with the cache, and is configured to operate in a full cache purge mode and a selective cache purge mode. In response to invoking one or both of the full cache purge mode and the selective cache purge mode, the processor performs a pipe pass on a selected addressable index to determine a number of valid compartments and a number of invalid compartments, and performs an eviction operation on the valid compartments while skipping the eviction operation on the invalid compartments.
