Abstract
A processor includes a plurality of nodes arranged two dimensionally in the X-axis direction and in the Y-axis direction, and each of the nodes includes a processor core and a distributed shared cache memory. The processor also includes a first connecting unit and a second connecting unit. The first connecting unit connects adjacent nodes in the X-axis direction among the nodes, in a ring shape. The second connecting unit connects adjacent nodes in the Y-axis direction among the nodes, in a ring shape. The cache memories included in the respective nodes are divided into banks in the Y-axis direction. Coherency of the cache memories in the X-axis direction is controlled by a snoop system. The cache memories are shared by the nodes.
