SIMD TYPE MICROPROCESSOR, DATA TRANSFER UNIT, AND DATA CONVERSION UNIT

PROBLEM TO BE SOLVED: To pack data of bit width less than bit width of a register in the register to transfer to a SIMD (single instruction-stream multiple data-stream) type microprocessor. SOLUTION: In this SIMD type microprocessor having ports by which a register built-in an arbitrary processor element can be accessed from external by inputting an address appointing each processor element, these ports are divided into high order bit side and lower bit side. The SIMD type microprocessor is composed so that transfer is performed at the high order bit side and the lower bit side of one processor element in an access once when data transfer is performed among registers of each processor element through the ports, or being composed so that the transfer is performed at the high order bit side and the lower bit side of two processor elements in an access once.
