摘要： A microprocessor instruction translator translates a conditional load instruction into at least two microinstructions. An out-of-order execution pipeline executes the microinstructions. To execute a first microinstruction, an execution unit receives source operands from the source registers of a register file and responsively generates a first result using the source operands. To execute a second the microinstruction, an execution unit receives a previous value of the destination register and the first result and responsively reads data from a memory location specified by the first result and provides a second result that is the data if a condition is satisfied and that is the previous destination register value if not. The previous value of the destination register comprises a result produced by execution of a microinstruction that is the most recent in-order previous writer of the destination register with respect to the second microinstruction.

摘要： An instruction translator receives a conditional load/store instruction that specifies a condition, destination/data register, base register, offset source, and memory addressing mode. The instruction instructs the microprocessor to load data from a memory location into the destination register (conditional load) or store data to the memory location from the data register (conditional store) only if the condition flags satisfy the condition. The offset source specifies whether the offset is an immediate value or a value in an offset register. The addressing mode specifies whether the base register is updated when the condition flags satisfy the condition. The instruction translator translates the conditional load instruction into a number of microinstructions, which varies as a function of the offset source, addressing mode, and whether the conditional instruction is a conditional load or store instruction. An out-of-order execution pipeline executes the microinstructions to generate results specified by the instruction.

摘要： An instruction translator translates a conditional store instruction (specifying data register, base register, and offset register of the register file) into at least two microinstructions. An out-of-order execution pipeline executes the microinstructions. To execute a first microinstruction, an execution unit receives a base value and an offset from the register file and generates a first result as a function of the base value and offset. The first result specifies the memory location address. To execute a second microinstruction, an execution unit receives the first result and writes the first result to an allocated entry in the store queue if the condition flags satisfy the condition (the store queue subsequently writes the data to the memory location specified by the address), and otherwise kills the allocated store queue entry so that the store queue does not write the data to the memory location specified by the address.

摘要： A microprocessor having performs an architectural instruction that instructs it to perform an operation on first and second source operands to generate a result and to write the result to a destination register only if its architectural condition flags satisfy a condition specified in the architectural instruction. A hardware instruction translator translates the instruction into first and second microinstructions. To execute the first microinstruction, an execution pipeline performs the operation on the source operands to generate the result. To execute the second microinstruction, it writes the destination register with the result generated by the first microinstruction if the architectural condition flags satisfy the condition, and writes the destination register with the current value of the destination register if the architectural condition flags do not satisfy the condition.

摘要： An architectural instruction instructs a microprocessor to perform an operation on first and second source operands to generate a result and to write the result to a destination register only if architectural condition flags satisfy a condition specified in the architectural instruction. A hardware instruction translator translates the architectural instruction into first and second microinstructions. To execute the first microinstruction, an execution pipeline performs the operation on the source operands to generate the result, determines whether the architectural condition flags satisfy the condition, and updates a non-architectural indicator to indicate whether the architectural condition flags satisfy the condition. To execute the first microinstruction, if the non-architectural indicator updated by the first microinstruction indicates the architectural condition flags satisfy the condition, it updates the destination register with the result; otherwise, it updates the destination register with the current value of the destination register.

摘要： A microprocessor includes a hardware instruction translator that translates an architectural instruction into first and second microinstructions. To execute the first microinstruction, an execution pipeline performs the shift operation on the first source operand to generate the first result and a carry flag value and updates a non-architectural carry flag with the generated carry flag value. To execute the second microinstruction, it performs the second operation on the first result and the second operand to generate the second result and new condition flag values based on the second result. If a architectural condition flags satisfy the condition, it updates the architectural carry flag with the non-architectural carry flag value and updates at least one of the other architectural condition flags with the corresponding generated new condition flag values; otherwise, it updates the architectural condition flags with the current value of the architectural condition flags.

摘要： A microprocessor includes an instruction translator that translates PUSHF, POP, and MOVSB x86 macroinstructions into multiple microinstructions that include a fused store microinstruction. For PUSHF, first and second microinstructions moves the x86 EFLAGS register into and mask off bits in a temporary register, and the fused store microinstruction stores it to a memory location. For POP, a first microinstruction loads a first memory location value into a temporary register and the fused store microinstruction stores it to the second memory location. For MOVSB, the first microinstruction loads a first memory location operand into a temporary register and the fused store microinstruction stores it to a second memory location. A reorder buffer receives the fused store microinstruction into exactly one entry. In response to the fused store microinstruction, an instruction dispatcher dispatches store address and store data microinstructions, neither of which occupies a reorder buffer entry, to different respective execution units.
