Abstract
A soft cache system compares tag bits of a virtual address with tag fields of a plurality of soft cache register entries, each entry associated with an index to a corresponding cache line in virtual memory. A cache line size for the cache line is programmable. When the tag bits of the virtual address match the tag field of one of the soft cache entries, the index from that entry is selected for generating a physical address. The physical address is generated using the selected index as an offset to a corresponding soft cache space in memory.
