摘要:

Two new processor arrays for the 2D discrete Fourier transform are proposed. Both structural schemes are oriented towards VLSI technology. They can be used in the construction of high-throughput processors for multidimensional and fast Fourier transforms as well as triple matrix mutiplication. The first structural scheme consists of two successively connected one-dimensional arrays of processor elements (PEs), and the second one represents a single array of more complex PEs. The advantages of these structural schemes are the localisation of all data exchanges between PEs and the absence of necessity of matrix transposition.
