Abstract
PURPOSE: To give the inversion or noninversion to the contents of the sequential field of the microorder in accordance with the result of the branch test designated by the microorder and then giving the address control to the next microorder according to the inverted or noninverted contents.
CONSTITUTION: The microorder which performs the conditional branching via control memory 10 is read out to register 12, and the test result is applied to line 15. Selector 14 applies the contents or inverted contents of the sequential field of register 12 to decoder 16 of address control circuit 11 according to the test result. Thus decoder 16 gives the control to selection gate 17 to select one of address register 22, head address register 18, jumping destination address register 19 and stack address register 20 each. And control memory 10 receives an access via the selected address.
