ABSTRACT:
A micro-processor includes an arithmetic logic unit (ALU) for executing a computer program stored in memory. The micro-processor further includes a condition comparison memory unit, such as a content addressable memory for example, which is connected to the ALU via a data bus. The condition comparison memory unit stores a) comparison patterns for a plurality of comparison operations, and b) output values which correspond to the comparison patterns. Upon receiving an operand of a comparison operation from the ALU, the condition comparison memory unit generates an output value corresponding to the comparison pattern which is coincident with the operand. The generated output value represents a memory address from which the computer program is subsequently executed. The micro-processor also includes an execution control unit which controls the ALU and the condition comparison memory unit.
