A core cluster, and energy scalable vector processing apparatus and method including the core cluster

PURPOSE: An energy scalable vector processing apparatus including a core cluster and a method thereof are provided to regulate the amount of energy consumption by making the core cluster share a cache memory. CONSTITUTION: A cache memory(130-6) stores and offers a command or a data. A core(110-6) performs calculation by accessing the cache memory or a cache memory which is installed in other adjacent core cluster. If the core requests a memory access, a cluster cache controller(120-6) accesses the core to the cache memory. If the core requests a clustering to the adjacent core cluster, the cluster cache controller accesses the core to the cache memory included in the adjacent core cluster.
