The Radon transform on a dynamically switched transputer network

Previously reported work resulted in a transputer tree network using thirty tramputers to perform the Radon transform. The Radon transform was used to enhance linear features in noisy synthetic aperture radar images. The work presented here describes modification of the transputer network by the addition of INMOS B004 link switches, and controlling T222 transputer. The tree configuration is replaced such that link switches now dynamically switch between the image data source transputer (farmer) and the transputers which perform the calculations (workers). It is shown that this arrangement is more cost-effective since the worker transputers are all relieved of their data-routing role. The paper Includes a comparison of the previous tree network with the new switched network, and presents results for both techniques.
