Abstract

Discusses the use of the systolic processor with a reconfigurable interconnection network of transputers, (SPRINT) systolic processor, developed at Lawrence Livermore National Laboratory, for image processing and implementing the radon transform for computed tomography. As a highly parallel processor, configured with nearest-neighbor communication between processors, the SPRINT is shown to be ideally suited for these applications, performing approximately 300 times the speed of a VAX-11/780. A block diagram of the SPRINT is shown. The SPRINT´s processors can operate in single-instruction multiple-data (SIMD) or multiple-instruction multiple-data (MIMD) mode. Each of its 64 processors is an INMOS Transputer, 1 32-b single-chip microprocessor. Performance results are summarized.<>
