The Effects Of Finite Computational Accuracies On Several Cosine Transform Architectures
E. H. Wrench · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1976
Three discrete cosine transform architectures are modeled to include the computational limitations expected in hardware implementations. The models are used to compare the performance of architectures using the chirp Z algorithm, prime transform algorithm, and a fast digital algorithm. The models have been simulated on a digital computer, and the resulting images are presented.
