Array Processor Implementation of 2-D Digital Filters

摘要

The recent introduction of array processors for fast scientific computation has had an important impact on the field of digital signal processing. This paper investigates the potential application of the array processor (AP) to the implementation of 2-D finite impulse response (FIR) digital filters via the 2-D FFT algorithm. Both CPU and I/O effects are discussed, and architecture considerations, such as the amount of memory available in the AP, are analyzed with respect to their impact on the filtering algorithm. 1 figure.
