The proposed systolic array does not require any preloading of input data and it produces output data at boundary PEs. No networks for intermediate spectrum transposition between constituent 1-dimensional transforms are required; therefore the entire processing is fully pipelined. This approach also has...
FFT with Reduced Complexity and Its Application to a CORDIC-Based Reconfigurable Systolic ArrayFFTIFFTCORDICCORSAEngineThis paper presents a new method by which FFT/IFFT can be implemented on a CORDIC-based processor. A radix-2 FFT is considered, where in contrast to conventional method of ...
The use of the linear transformation method to systolize the Warshall algorithm for computing the transitive closure of a graph on a mesh-connected array (without wraparound connections) is discussed. The technique is extended to design linear systolic arrays. The advantage of this approach is eas...
An Instruction Systolic Array (ISA) implementation of the two-dimensional Fast Fourier Transform (FFT) algorithm is presented in this paper. The ISA is characterised by a systolic flow of instructions instead of data as in ordinary systolic array. The ISA implementation of the two-dimensional FFT...
A bit-level systolic array system is proposed for the Winograd Fourier Transform Algorithm. The design uses bit-serial arithmetic and, in common with other systolic arrays, features nearest neighbour interconnections, regularity and high throughput. The short interconnections in this method contrast favou...
Reconfigurable systolic array architectures that support different DSP functions including DFT/FFT have been documented in [27–29] and will be considered in the context of current work in later sections. In this paper, a scalable systolic array architecture which can be configured to function as ...
The structural property of parallel recursive algorithms points to the feasibility of a Hierarchical Iterative Flow-Graph Design (HIFD) of VLSI Array Processors. The proposed array processor architectures, we believe, will have significant impact on the development of future supercomputers. CAS-1 JCR-...

This particular systolic array computer is named Warp, suggesting that it can perform computations at a very high speed. The 10-cell systolic array, with one cell implemented on one board, can process 1024-point complex FFTs at a rate of one FFT every 600 µ;s. Under program control, ...
