Abstract: Embodiments of systems, apparatuses, and methods for performing BIDSplit instructions in a computer processor are described. In some embodiments, the execution of a BIDSplit instruction tests the encoding of a binary-integer decimal source value and extracts a sign, exponent, and/or significand into a destination.

Abstract: An apparatus includes packed data registers and an execution unit. An instruction is to indicate a first source packed data that is to include a first packed data elements, a second source packed data that is to include a second packed data elements, and a destination storage location. The execution unit, in response to the instruction, is to store a packed data result that is to include packed result data elements in the destination storage location. Each of the result data elements is to correspond to a different one of the data elements of the second source packed data. Each of the result data elements is to include a multiple bit comparison mask that is to include a different comparison mask bit for each different corresponding data element of the first source packed data compared with the corresponding data element of the second source packed data.

Abstract: Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for vectorized searching for a pattern P within a set of data T, the pattern P having a length m. In various embodiments, the vectorized search may include a shift of a sliding window into T by a distance d that is greater than m on determination, based on one or more ordered vectorized comparisons of portions of P and T, that no potential match of P is found within the sliding window. In various embodiments, d and m may be positive integers. In various embodiments, the one or more ordered vectorized comparisons may include one or more single instruction multiple data (“SIMD”) instructions supported by the processor.
