Patent ID: 10296457

Abstract:
A processor includes a processing core to execute a transaction with a memory via a cache and a cache controller, associated with the processor, comprising an index mapper circuit to identify a physical memory address associated with the transaction, wherein the physical memory address comprises a plurality of bits, determine, based on the plurality of bits, a first set of bits encoding a tag value, a second set of bits encoding a page index value, and a third set of bits encoding a line index value, determine, based on the tag value, a bit-placement order for combining the second set of bits and the third set of bits, combine, based on the bit-placement order, the second set of bits and the third set of bits to form an index, and generate, based on the index, a mapping from the physical memory address to a cache line index value identifying a cache line in the cache, wherein the processing core is to access, based on the cache line, a memory location referenced by the physical memory address.
