Data-flow diagram for dedispersion, incorporating the stages of “write data,” “transpose,” “sub-band dedispersion,” and “shift data.” In this diagram, green memory blocks are used to buffer incoming data, and blue blocks serve as buffers for transposed data, where the dedispersion process takes place. The shaded patterns within the diagram illustrate the data mapping at various steps: (1) In the “write data” step, the shaded pattern represents the positions where the input data are written. (2) In the “transpose” step, the shaded pattern illustrates how the dedispersed data are transposed in buffers 1 and 2. (3) In the “sub-band dedispersion” step, the shaded pattern represents the dedispersion of the data. (4) In the “shift data” step, the shaded pattern illustrates the mapping of the data as they are shifted.
