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

摘要

A core cluster includes a cache memory, a core, and a cluster cache controller. The cache memory stores and provides instructions and data. The core accesses the cache memory or a cache memory provided in an adjacent core cluster, and performs an operation. The cluster cache controller allows the core to access the cache memory when the core requests memory access. The cluster cache controller allows the core to access the cache memory provided in the adjacent core cluster when the core requests a clustering to the adjacent core cluster. The cluster cache controller allows a core provided in the adjacent core cluster to access the cache memory when the core receives a clustering request from the adjacent core cluster.
