Abstract
A parallel processor is provided with a plurality of independently operable command units and a plurality of function units each connected to the command unit. A data unit, a register file, and a carry bit are shared such that the command and function units operate in parallel without any conflict. A priority scoreboard is provided to control the register file so that the command units operate independently according to the parallelism of a program, and detect and avoid a contention for a register according to the order of priority, making simultaneous execution of a plurality of commands possible, resulting in the increased process speed.
