Abstract
A floating point register stack for a processor combines a plurality of two general purpose registers to form a register stack for x86 instructions and leaves the remaining general purpose registers for native instructions of the processor. By mapping x86 sources into the stack of two general purpose registers and operating x86 instructions on the x86 stack, the register stack for the processor is able to support both the processor's native instruction set and the x86 instruction set without increasing the size of the register stack.
