SYSTEM AND METHOD FOR ADAPTIVELY MANAGING REGISTERS IN AN INSTRUCTION PROCESSOR

摘要

Systems and methods for adaptively managing registers in an instruction processor are disclosed. The system identifies one or more registers with inoperable cells. An operand manager identifies a set of operable cells within the one or more registers with inoperable cells and determines if a present instruction will use an operand that can be supported by the set of operable cells. When the set of operable cells can support the operand, the operand manager generates an assignment which is communicated to a register file manager.

1. A method for adaptively managing registers in a processor, the method comprising:
locating at least one member register from a set of available registers having at least one inoperable cell among the cells forming the at least one member register; identifying a set of operable cells in the at least one member register that has at least one inoperable cell; in response to an indication that an operand can be supported by less than a nominal number of cells, determining if the set of operable cells in the at least one member register that has at least one inoperable cell can support the operand; and in response to determining that the set of operable cells in the at least one member register that has at least one inoperable cell can support the operand:
generating an assignment that logically couples the set of operable cells to the operand; andnotifying a register file manager of the assignment.
