Method to handle instructions that use non-windowed registers in a windowed microprocessor capable of out-of-order execution |
摘要 |
A method for handling instructions that use non-windowed registers in an out-of-order microprocessor with windowed registers is provided. When an instruction with a non-windowed destination register is detected, the computed result of the instruction is stored in a temporary storage register instead of the non-windowed register designated as the instruction's destination. When the instruction is ready for retirement, the result is transferred from the temporary storage register into the non-windowed register designated as the instruction's destination. When another instruction's source register is a non-windowed register, the microprocessor determines whether the instruction should use data from the designated non-windowed register or from a temporary storage register, to prevent the other instruction from using incorrect data. |
