Simd processor and control processor, and processing element with address calculating unit

Abstract

To improve processing efficiency of a SIMD processor that divides two-dimensional data into blocks, each having a width of PE number N, to store the data in a local memory of each of PEs by a lateral direction priority method. When designating a local address of N pieces of data arranged in a row direction from head data whose coordinate values in two-dimensional data are (X,Y) to a PE array, the N pieces of data being stored in local memories, a CPbroadcasts a local address A, a local address A, and a threshold number Z obtained by an address calculation unit. Each of the PEs compares a magnitude relation between the threshold number Z and its own number, and selects one of the local address Aand the local address Aaccording to the comparison result.
