PURPOSE:To minimize the idle time due to a data waiting time by prefetching the mask vector data and supplying this data at a high speed to a processing part from a mask vector data buffer. CONSTITUTION:A memory 10 stores a mask vector containing plural mask vector data. These data are successively prefetched by a mask vector data buffer 11 from the memory 10 and read by a mask vector data reading part 30a. These vector data are collectively processed by a mask vector data processing part 40. While an arithmetic unit 60 and an address producing part 50 are connected to the memory 10 and the part 40 respectively. The actions of these parts are controlled by a controller 20. |
