PROBLEM TO BE SOLVED: To achieve a processor for efficiently performing arithmetic processing of a large amount of data at high speed. SOLUTION: Arithmetic processing instructions to a main arithmetic circuit (20) are stored in a form of a microprogram in a micro-instruction memory (21), and the operation control of the main arithmetic circuit is carried out under the control of a controller 22 according to the microprogram. In the main arithmetic circuit (20), a memory cell mat (30) is divided into entries each storing a plurality of bits of data, and arithmetic and logic units (ALUs) are arranged corresponding to the respective entries. Arithmetic processing is carried out between the entries and the ALUs in a bit serial mode in parallel to the respective entries. The large amount of data can be efficiently processed according to a microprogram control system. COPYRIGHT: (C)2011,JPO&INPIT
