    Abstract: An apparatus includes one or more registers configured to store a vector of input values. The apparatus also includes a coefficient determination unit configured to, responsive to execution by a processor of a single instruction, select a plurality of piecewise analysis coefficients. The plurality of piecewise analysis coefficients includes one or more sets of piecewise analysis coefficients, and each set of piecewise analysis coefficients corresponds to an input value of the vector of input values. The apparatus further includes arithmetic logic circuitry configured to, responsive to the execution of at least the single instruction, determine estimated output values of a function based on the plurality of piecewise analysis coefficients and the vector of input values.

    Abstract: A device includes a vector register file, a memory, and a processor. The vector register file includes a plurality of vector registers. The memory is configured to store a permutation instruction. The processor is configured to access a periodicity parameter of the permutation instruction. The periodicity parameter indicates a count of a plurality of data sources that contain source data for the permutation instruction. The processor is also configured to execute the permutation instruction to, for each particular element of multiple elements of a first permutation result register of the plurality of vector registers, select a data source of the plurality of data sources based at least in part on the count of the plurality of data sources and populate the particular element based on a value in a corresponding element of the selected data source.
