Abstract
A cache memory is shared by N cores of a processor. The cache memory includes a unified tag part and a sliced data part partitioned into N data slices. Each data slice of the N data slices is physically local to a respective one of the N cores and physically remote from the other N-1 cores. For each core, the cache memory biases allocations caused by the core towards a physically local slice of the core. The cache memory may be arranged as a set-associative cache memory, and allocations may be based on a miss rate of a data slice and a number of M ways allocated to a core. A dispatch queue dispatches requests in a schedule fashion so that only one of the N data slices at a time returns data to each core.
