Abstract

An example method for placing one or more element data values into an output vector includes identifying a vertical permute control vector including a plurality of elements, each element of the plurality of elements including a register address. The method also includes for each element of the plurality of elements, reading a register address from the vertical permute control vector. The method further includes retrieving a plurality of element data values based on the register address. The method also includes identifying a horizontal permute control vector including a set of addresses corresponding to an output vector. The method further includes placing at least some of the retrieved element data values of the plurality of element data values into the output vector based on the set of addresses in the horizontal permute control vector.
