Radon Transform Computer for Multidimensional Signal Processing

摘要

A high-speed Radon transform computer (RTC) has been designed and simulated that operates the principles of the Parallel Projection Pipeline Engine (PPPE) processor suggested by Sanz, et al.. The computer consists of an array of identical processing elements with fast communication links to each of its neighbors and uses forward- and back-projection formulas using linear interpolation. Simulation and experimental timing results have been performed on both a systolic array of 64 Transputer processors and on arrays of commercial DSP chips. A custom VLSI implementation is currently under design which is expected to perform forward and inverse transforms of 512 by 512 images at or near video rates. 9 refs., 1 fig., 1 tab.
