Abstract
A processor with multiple execution units for instruction processing is provided. The processor comprises an instruction decode and issue logic and a control logic for resolving register access conflicts between subsequent instructions and a dependency cache, which comprises a receiving logic for receiving an execution unit indicator indicative of the execution unit the instruction is planned to be executed on, a storing logic responsive to the receiving logic for storing the received execution unit indicator, and a retrieving logic responsive to a request from the instruction decode and issue logic for providing the stored execution unit indicator for an instruction. The instruction decode and issue logic is adapted for requesting execution unit indicator for an instruction from the dependency cache and to assign the instruction to one respective of the execution units dependent on the execution unit indicator received from the dependency cache.
