摘要： A method and apparatus for a two micro-operation flow using source override. In one embodiment, the method includes the identification of a macro-instruction having one or more streaming single instruction multiple data extension type operands. Once received, the macro-instruction is decoded into a first micro-operation (uOP) and a second uOP. Once decoded, a signal is asserted to disable source operand override logic if the first micro-operation updates a logical destination register that matches a logical source register of the micro-operation. Otherwise, the mutual source override is active and executed by a register alias table (RAT) when uOP with matching logic source and destination register are detected in a same clock cycle. In doing so, macro-instructions having 128-bit operands may be processed using, for example, two uOPs (one for the lower half and one for the upper half) in a 64-bit implementation, while preserving the atomicity of the original instruction.

摘要： An apparatus is described having instruction execution logic circuitry. The instruction execution logic circuitry has input vector element routing circuitry to perform the following for each of three different instructions: for each of a plurality of output vector element locations, route into an output vector element location an input vector element from one of a plurality of input vector element locations that are available to source the output vector element. The output vector element and each of the input vector element locations are one of three available bit widths for the three different instructions. The apparatus further includes masking layer circuitry coupled to the input vector element routing circuitry to mask a data structure created by the input vector routing element circuitry. The masking layer circuitry is designed to mask at three different levels of granularity that correspond to the three available bit widths.

摘要： An apparatus is described having instruction execution logic circuitry to execute first, second, third and fourth instruction. Both the first instruction and the second instruction insert a first group of input vector elements to one of multiple first non overlapping sections of respective first and second resultant vectors. The first group has a first bit width. Each of the multiple first non overlapping sections have a same bit width as the first group. Both the third instruction and the fourth instruction insert a second group of input vector elements to one of multiple second non overlapping sections of respective third and fourth resultant vectors. The second group has a second bit width that is larger than said first bit width. Each of the multiple second non overlapping sections have a same bit width as the second group. The apparatus also includes masking layer circuitry to mask the first and third instructions at a first resultant vector granularity, and, mask the second and fourth instructions at a second resultant vector granularity.

摘要： In some disclosed embodiments instruction execution logic provides conditional memory fault assist suppression. Some embodiments of processors comprise a decode stage to decode one or more instruction specifying: a set of memory operations, one or more register, and one or more memory address. One or more execution units, responsive to the one or more decoded instruction, generate said one or more memory address for the set of memory operations. Instruction execution logic records one or more fault suppress bits to indicate whether one or more portion of the set of memory operations are masked. Fault generation logic is suppressed from considering a memory fault corresponding to a faulting one of the set of memory operations when said faulting one of the set of memory operations corresponds to a portion of the set of memory operations that is indicated as masked by said one or more fault suppress bits.

摘要： Methods and apparatus are disclosed for using an index array and finite state machine for scatter/gather operations. Embodiment of apparatus may comprise: decode logic to decode a scatter/gather instruction and generate a set of micro-operations, and an index array to hold a set of indices and a corresponding set of mask elements. A finite state machine facilitates the gather operation. Address generation logic generates an address from an index of the set of indices for at least each of the corresponding mask elements having a first value. An address is accessed to load a corresponding data element if the mask element had the first value. The data element is written at an in-register position in a destination vector register according to a respective in-register position the index. Values of corresponding mask elements are changed from the first value to a second value responsive to completion of their respective loads.
