Abstract: Systems and method for reading data samples in reverse group order are described herein according to various embodiments of the present disclosure. In one embodiment, a method for reading data samples in a memory is provided, wherein the data samples correspond to an operand of a vector operation, the data samples are grouped into a plurality of different groups, and the different groups are spaced apart by a plurality of addresses in the memory. The method comprises reading the groups of data samples in reverse group order, and, for each group, reading the data samples in the group in forward order.

Abstract: Systems and methods for generating twiddle factors are described herein according to various embodiments of the present disclosure. In one embodiment, a method for twiddle factor generation comprises generating a first twiddle phase, wherein the first twiddle phase is from a set of radix-M1 twiddle phases, and M1 is an integer. The method also comprises converting the first twiddle phase into a second twiddle phase, wherein the second twiddle phase is from a set of radix-M2 twiddle phases, and M2 is an integer that is different from M1. The method further comprises generating a twiddle factor based on the second twiddle phase.
