One of the first and second high-speed memories is read to obtain output patterns and, at the same time, the plurality of low-speed memories are simultaneously read and the read-out data are successively written in the other high-speed memory alternately with each other. Upon completion of pattern generation from the one high-speed memory, pattern generation from the other high-speed memory is achieved.
