摘要

A microcode RAM (105) obtains, from a host computer (120), a microcode including an instruction sequence and a composite instruction sequence coupling a plurality of instruction sequences together to sort the micro instructions and to process the plurality of instruction sequences in a parallel manner and stores the obtained microcode. An address table (103) obtains the header address of the microcode from the host computer (120), and stores the obtained header address. An FIFO buffer (101) stores information on a vertex subjected to an arithmetic processing and an instruction sequence index for identifying the content of the arithmetic processing for the information on the vertex. An instruction determination unit (102) selects the microcode based on the successive instruction sequence indexes obtained from the FIFO buffer (101). An arithmetic processing execution unit (106) executes the arithmetic processing on the information on the vertex based on the microcode selected by the instruction determination unit (102).
