In order to delay the designated data from RZ decoder (36) the entry control latch register (33) is provided on the input side of the RZ decoder (36). The command signal through a memory bus (16) is read in program memory control device (12'). The command signal is inputed to command register (92) and through the command decoder (94) , ROM address decoder (96). ROM (read only memory) reads the microcommand signals and temporarily stores them in microcommand register (32). The microcommand signals are composed of 3 register fields (RX, RY, RZ) and function field (FUNC). |
