Abstract
An arithmetic processing apparatus includes: first and second core groups each including cores, a first to an Nth (N is plural) caches that process access requests from the cores, and an intra-core-group bus through which the access requests from the cores are provided to the first to Nth caches; and a first to an Nth inter-core-group buses each provided between the first to Nth caches in the first and second core groups respectively. The first to Nth caches in the first core group individually store data from a first to an Nth memory spaces in a memory, respectively. The first to Nth caches in the second core group individually store data from an N+1th to a 2Nth memory spaces, respectively. The first to Nth caches in the first core group access the data in the N+1th to 2Nth memory spaces, respectively, via the first to Nth inter-core-group buses.
