Generating lookahead tracked register value based on arithmetic operation indication |
摘要 |
Apparatus and methods to track a register value. A microprocessor can include a first register, a control circuit, and an adder. The first register can store a tracked register value. The control circuit can include an instruction input to receive at least a portion of an instruction and a first output to output an arithmetic operation indication. The adder can include a control input to receive the arithmetic operation indication, a first input to receive an immediate operand of an instruction, and a second input to receive the tracked register value.
