摘要： A multi-granularity parallel FFT computation device including three memories, a butterfly computation device, a state control unit, a data reversing network and a first selector. The three memories are each a multi-granularity parallel memory, and store butterfly group data and twiddle factors corresponding to the butterfly group data. The butterfly computation device perform computations of a butterfly group based on the butterfly group data outputted from the first selector and the corresponding twiddle factors outputted from one of the memories, and write a computation result back to the other two memories. The device can read butterfly group data and corresponding twiddle factors in parallel from the multi-granularity parallel memories with a specific R/W granularity. No memory conflict will occur in the read operation, and no additional process is required for sorting the read/written data.

摘要： The present disclosure provides A data access method and device for parallel FFT computation. In the method, FFT data and twiddle factors are stored in multi-granularity parallel memories, and divided into groups throughout the computation flow according to a uniform butterfly representation. Each group of data involves multiple butterflies that support parallel computation. Meanwhile, according to the butterfly representation, it is convenient to generate data address and twiddle factor coefficient address for each group. With different R/W granularities, it is possible to read/write data and corresponding twiddle factors in parallel from the multi-granularity memories. The method and device further provide data access devices for parallel FFT computation. In the method and device, no conflict will occur during read/write operations of memories, and no extract step is required for sorting the read/written data. Further, the method and device can flexibly define the parallel granularity according to particular applications.
