Abstract
PURPOSE: To reduce the bit width of ROM and to increase the process velocity by providing the control ROM in addition to the ROM to store the microprogram with no addition of the ROM's access time to the operation time and preparing the information necessary for the operation before the process cycle.
CONSTITUTION: The following units are installed: 1st ROM12 to store the microprogram; address controller 11 to give control to the address to give an access to ROM12; and 1st data register 13 to ratch the information of ROM12 via the address designated by controller 11. Furthermore, 2nd ROM15 is added to receive an access by part of the output ratched to register 13 and then to deliver the control signal, along with 2nd register 16 to ratch the output of ROM15, and arithmetic logic circuit 18 to carry out the arithmetic process by the output of register 16. Thus, the control information of the next order plus the further subsequent order are fetched under the arithmetic process of a certain order.
