Managing a Register Cache Based on an Architected Computer Instruction Set Having Operand Last-User Information |
摘要 |
A multi-level register hierarchy is disclosed comprising a first level pool of registers for caching registers of a second level pool of registers in a system wherein programs can dynamically release and re-enable architected registers such that released architected registers need not be maintained by the processor, the processor accessing operands from the first level pool of registers, wherein a last-use instruction is identified as having a last use of an architected register before being released, the last-use architected register being released causes the multi-level register hierarchy to discard any correspondence of an entry to said last use architected register.
