The Design of Reconfigurable Cache Scheme in Multi-core Processor

To deal with massive and parallel data processing, the paper proposed a design solution of reconfigurable cache for multi-core processor.The work included the design of reconfigurable cache structure and its operation scheme, as well as a reconfiguration context word generation method, named as Dynamic Cache Associativity Configuration(DCAC)method.The experiments verified that with 4.07% overhead in hardware cost, the design solution won a 16.13% reduction of miss penalty in average for the core nearby caches with dynamic cache associativity reconfiguration method.
