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.

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.
