A device includes a processor and a memory configured to store instructions. The processor is configured to receive a particular instruction from among the instructions and to execute the particular instruction to generate first output data corresponding to a sum of first input data and second input data. The processor is also configured to execute the particular instruction to perform a divide operation on the second input data and to generate second output data corresponding to a difference of the first input data and a result of the divide operation.

Instruction applicable to radix-3 butterfly computation

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.
