Abstract

PURPOSE:To improve both the efficiency and the processing speed of the titled system, by detecting rationally the originating timing of the subsequent instructions in case the result operand of a preceding vector instruction is used as an input operand for the subsequent vector instruction. CONSTITUTION:A fetched vector instruction is set to an instruction fetching register 11. The vector instruction of the register 11 is decoded by a decoder 12, and the decoded instruction information is set to a queuing register 13. An instruction originating control circuit 14 reads the information out of the register 13 and the under-execution instruction control parts 15-1 and 15-2 to feed the start information to an arithmetic processing part and at the same time feeds the instruction information within the register 13 to the parts 15-1 and 15-2. The parts 15-1 and 15-2 contain the under-execution instruction registers 16-1 and 16-2, the counter circuits 17-1 and 17-2 and the write flags 18-1 and 18-2 respectively.
