Computer program product for modifying associated value of logical address in computing unit, includes instructions for mapping logical address to memory location in register allocator by special register identifier

摘要

An instruction containing a statement as a logical value in expressed destination register is received by an instruction decoder (112). A determination is made whether a result of instruction is set to a constant value in destination register by the instruction decoder. The destination register is provided in a physical register file (106) associated with an execution unit (102). The logical address is mapped to a memory location in a register allocator (114) by a special register identifier. Independent claims are included for the following: (1) a method for modifying associated value of logical address in computing unit; and (2) a system for modifying associated value of logical address in computing unit.
