Abstract
PURPOSE: To extend the range of the address capable of being assigned to the microword without limiting the control operation designated by the microword by providing a positional information in the microword.
CONSTITUTION: In the microword, there are included an operation field (OP), a control field (CF), an address field (NA), a branch test upper field (H), and a branch test lower field (L) as well as an address position information (B). The microprogram control device 100 reads out the microword from the memory 101, 101 for memorizing the microword and comprises a microprogram control circuit 102 for carrying out the various types of control operations, an address register 103 and an address control circuit 104 for forming an address set at the address register 103.
