STORAGE MANAGEMENT

摘要

In a computer system having a system memory (12), m architected logical register and an array (30) of n physical registers, where n is greater than m, a method of managing storage operands including the steps of: detecting the decoding of an instruction having at least one field specifying a storage operand; identifying an available one of the physical registers; fetching the storage operand from the system memory; loading the storage operand into the available one of the physical registers; and executing the instruction, using the storage operand stored in the one of the physical registers.
