Abstract

PURPOSE: To inspect the propriety of μPG of additional functions and the structure of logic circuit, by comparing the data designating μPG of specific function with the data representing the specific functions of the logic circuit, in the computer of microprogram μPG control.
CONSTITUTION: One of the output pins of the package PKG1 constituting the additional functions of computer are connected to ground, and the additional function signal 3 is at L level with PKG1 present, and at H level with that absent. In a computer having the capacity of control memory 5 of 4K words, if the μPG of additional function is written in the final 1K words, the upper rank 2-bit of the address register 6 is the address signal 8 and it is compared with the signal 3 at the comparison circuit 4. When the content of the register 6 designates the μPG of additional function, if no additional function PKG is present and the signal 3 is at H level, the structure error signal 9 is outputted from the circuit 4. As a result, the execution of μPG is stopped, allowing to prevent malfunction.
