Abstract
PURPOSE: To realize plural units of multi-direction branch orders without increasing the bit width by designating the specified bit group of the unused branch destination address designated field and the selecting one of plural units of test circuits.
CONSTITUTION: Test results 50 and 51 which are selected via lower-rank two bits A4 and A5 of branch destination address designated field 30 are transmitted to branch destination address selection circuits 26 and 27 among the test results supplied to test result selection circuits 24 and 25 within arithmetic control circuit 5. And address lines 64 and 65 are selected in the case of the single-direction branch order designation via selection order 66 of branch conditions designated field 31; while output 50 and 51 of test result selection circuits 24 and 25 in the case of the multi-direction branch order designation respectively. At the same time, output 70 and 71 of selection circuits 26 and 27 are sent to address register 4, and then all bits of register 4 are filled up to decide the branch destination address.
