Abstract: A high-level synthesis multiprocessor system enables sophisticated algorithms to be easily realized by almost a smallest circuit. A shared memory is divided into a plurality of banks. The memory banks are connected to processors, respectively. Each processor receives an instruction code and an operand from its connected memory bank. After the operation execution, the processor sends the result to its adjacent processor element to set it as an accumulator value at the time of execution of a next instruction. A software program to be executed is fixed. A processor to execute each instruction in the software program is uniquely identified. Each processor has a function for executing its instruction out of all executable instructions in the multiprocessor system, and does not have a function for executing an instruction that the processor is not to execute. The circuit configuration with unused instructions deleted is provided.
