SIMD type arithmetic unit and arithmetic processing unit

摘要

PROBLEM TO BE SOLVED: To make a succeeding processing selectively executable by executing calculation through the use of two kinds of data to be stored in respective corresponding data storing parts between two input means and storing condition flags corresponding to the arithmetic results in the corresponding flag storing parts of an output means. SOLUTION: The arithmetic unit 1 simultaneously executes calculation being common to respective data classes by an arithmetic part 6 through the use of input data A0-A7 stored in the respective data storing parts R10-R17 of a first input register 2 and input data B0-B7 which are stored in the respective data storing parts R20-R27 of the second input register 4 and stores the flags T0-T7 corresponding to the arithmetic results in the flag storing parts F0-F7 of an output register 8. The flags TP and TA corresponding to the result of OR operation in the output flags T0-T7 which are stored in the flag storing parts R0-R7 are stored in the flag storing parts F8 and F9 of the output register 8.
