Implementation and Evaluation of Algorithms for Image Processing by Means of Transputer Network
نویسنده
چکیده
The problem investigated in this paper is to find a programming method for a Transputer type, processor network and to evaluate its performance on various algorithms for image processing. The original feature of our study is based upon the design of a modular architecture (acquisition/display module, Transputer module) and the definition of a programming method that is independant of the processor network topology. The architecture allows to connect several 4 transputers modules. The programming method defines 2 models : communication and processing and uses a communication scheme that ensures the portability of the application on the target configuration. The communication model is enhanced t o be 'full model' so that an algorithm can be implemented on any physical configuration. Our method has been tested on a 4 transputer network, it can be extended to a higher number. The measured response times show the efficiency of such a network and let hope to reach real time processing by adding transputer modules. The efficiency is increased by using parallelism between communication and processing, and managing consistently both of them to reduce the loss of time due to synchronization.
