As far as multimedia processing is concerned, a plurality of computations of a same type are often executed concurrently and hence a plurality of computing units having a same function are used and mode information for controlling the plurality of units by an instruction unit for one computing unit is prepared in each instruction to execute a plurality of computations with a single instruction.

Processor including a plurality of computing devices

An object of the prevent invention is to provide a processor that can execute many computations with a small number of instruction codes. As far as multimedia processing is concerned, a plurality of computations of a same type are often executed concurrently and hence a plurality of computing units having a same function are used and mode information for controlling the plurality of units by an instruction unit for one computing unit is prepared in each instruction to execute a plurality of computations with a single instruction.
