Abstract

This solution relates to machine vision computing environments, and more specifically relates to a system and method for selectively accelerating the execution of image processing applications using a cell computing system. The invention provides a high performance machine vision system over the prior art and provides a method for executing image processing applications on a Cell and BPE3 image processing system. Moreover, implementations of the invention provide a machine vision system and method for distributing and managing the execution of image processing applications at a fine-grained level via a PCIe connected system. The hybrid system is replaced with the BPE3 and the switch is also eliminated from the prior in order to meet over 1 GB processing requirement.

Claims
