Abstract
The invention features a computer with a condition code register file (the condition code register file is distinct from the computer's general purpose register file). The condition code register file has a plurality of addressable condition code registers. The computer executes condition-setting instructions that each produce a condition code value for storage in one of the condition code registers, and conditional branch instructions that branch to a target based on analysis of a condition code value from one of the condition code registers. The condition code registers are directly addressable by condition code address fields of the instructions. The invention finds primary expression in one of two embodiments (or in both simultaneously): either (a) at least some of the condition-setting instructions contain a direct address field that selects one, from among the plurality of the condition code registers into which the condition code value is to be stored, or (b) at least some of the conditional branch instructions contain a direct address field that selects one, from among the plurality of the condition code registers from which a condition code value is to be selected for analysis.
