Abstract
PURPOSE: To make a branch effectively in a short time by discriminating conditions simultaneously and by branching a program to predetermined branch destinations on the basis of results of the discrimination.
CONSTITUTION: Branch-destination address area JADD of instruction register 4 is assigned by F, O, 3 and four conditions A, B, C, and D, for example, are discriminated. On the basis of the results, four bits of a branch address expressed as hexadecimal number "0" are modified to make a branch to a predetermined branch destination. Four conditions AWD are selected by multiplexer 8 through the assignment of condition selective assignment area S. Presetting means 6 outputs condition A of "1" by setting a bit (e.g. A), which corresponds to a condition in preset assignment area PS to be preset, to "1". Mask means 7 outputs bit "0" as condition D by setting a bit, which corresponds to a condition (e.g. D) in mask assignment area MS to be preset, to "0". Under the conditions determined by said mask means 7 and presetting means 6, the branch destination address is determined.
