PROBLEM TO BE SOLVED: To reduce the number of SIMD type instructions without damaging the diversity of arithmetic functions. ;SOLUTION: An instruction decoder 5 discriminates a data type from a loading instruction and stores the data type in data type storage area 3a to 3c corresponding to registers 2a to 2c storing data. An SIMD computing element 4 determines the type of the data to be a computation object on the basis of the data stored in the data type storage areas 3a to 3c.;COPYRIGHT: (C)2003,JPO
