PURPOSE:To attain a graphic processing with the same hardware unit by applying the algorithm of a simple equation to the executing procedure of a multiplication/division circuit and using it to the operation of a graphic function. CONSTITUTION:An accelerator is constituted of an ALU, plural LSI having the processing procedure of simple equation, a RAM storing a microprogram, a trigonometrical function table, a curve function table, a cache memory, an FIFO, a pipeline bus 4 and a common bus 5. These accelerators 10-12 are connected with each other via both buses 4 and 5. The microprograms of different functions (curve generation/paint-out processing and perspection conversion processing) are loaded to the RAM of each accelerator via the bus 5 and in the initial process. Each accelerator gives the dividing process to said processing in terms of pipeline.
