Abstract
An example apparatus includes a plurality of execution units, a physical register file that includes a plurality of physical registers, an instruction buffer, and a scheduling circuit. The instruction buffer may receive a group of instructions to be performed by the plurality of execution units. The scheduling circuit may allocate a physical register of the plurality of physical registers in the physical register file to store an operand of a particular instruction of the group of instructions. The scheduling circuit may also, in response to determining that a result of the particular instruction is used as an operand for a different instruction of the group of instructions, assign a tag to the particular instruction and to the different instruction to indicate that the result of the particular instruction will be sent to the different instruction without using the physical register file.
