Abstract

The performance of BLITZEN, a new massively parallel machine, is compared with that of the Massively Parallel Processor (MPP) for two image-processing functions: rotation and resampling. These functions, as implemented on the MPP, were modified to exploit new architectural features of BLITZEN. The functional simulator of BLITZEN, used for algorithm development and timing information, is described. A performance comparison based on instruction cycle counts shows a significant speedup for the new machine due to architectural features that improve data movement capability
