ABSTRACT:
Apparatus for realizing instruction level parallel processing includes an instruction buffer for storing instructions fetched from a memory until the instructions are sent from the instruction buffer, an instruction register unit for storing and issuing the sent instructions to a plurality of execution units in the order of instruction, and a judgement part for judging whether it is possible to execute a set of unissued instructions to be next issued, in parallel, as stored in the instruction buffer and/or the instruction register unit and for controlling parallel processing of the set of instructions, based on the result of a judgement on the possibility of parallel processing.
