Abstract: A device system and method for processing program instructions, for example, to execute intra vector operations. A fetch unit may receive a program instruction defining different operations on data elements stored at the same vector memory address. A processor may include different types of execution units each executing a different one of a predetermined plurality of elemental instructions. Each program instruction may be a combination of one or more of the elemental instructions. The processor may receive a vector of data elements stored non-consecutively at the same vector memory address to be processed by a same one of the elemental instructions and a vector of configuration values independently associated with executing the same elemental instruction on the non-consecutive data elements. At least two configuration values may be different to implement different operations by executing the same elemental instruction using the different configuration values on the vector of non-consecutive data elements.

Abstract: A method for the generation of addresses of successive pairs of input data values of stages of a Fast Fourier Transform calculation stored contiguously in a memory includes initializing at most once per stage a first base address pointer to an address of a first input data value of an initial butterfly calculation of the stage and a second base address pointer to an address of a second input data value of the initial butterfly calculation, and initializing at most once per stage a first constant and a second constant. Pairs of input data values of successive butterfly calculations in the stage are then addressed using the first base address pointer, the second base address pointer, the first constant and the second constant.
