Abstract
The present invention provides a method and apparatus for floating-point register caching. One embodiment of the method includes mapping a first set of architected registers defined by a first instruction set to a memory outside of a plurality of physical registers. The plurality of physical registers are configured to map to the first set, a second set of architected registers defined by a second construction set, and a set of rename registers. This embodiment of the method also includes adding the physical registers corresponding to the first set of architected registers to the set of rename registers.
