Abstract
PURPOSE: To ensure a highly reliable control for the microprogram, by reading out the result of storage immediately after storing the result of operation and then comparing the result of storage with the result of operation which is held previously.
CONSTITUTION: The contents of the general-purpose register 1-1, is added to the contents of the generral-purpose register 1-2, and the result of this addition is stored in the register 1-2. In this case, the selecting circuit 2 selects the registor 1-1 for one cycle of the machine lock, and the selecting circuit 3 selects the register 1-2 respectively. And both the contents of the registers 1-1 and 1-2 are led to the arithmetic circuit 4, and the result of the operation and others are stored into the registers 5 and 1-2 each. Furthermore, a comparison is given between the result of operation of the register 1-2 stored in the circuit 3 and the output given from the register 5 of selection circuit 6. Thus a confirmation is given whether the result of operation could be stored correctly into the general- purpose registers. In such way, a highly reliable control is possible for the microprogram.
