The processor was designed with a high degree of parallelism to speed up a range of image processing operations. Data parallelism found in array processors has been included into the architecture of the proposed processor. The implementation of commonly used image processing algorithms and their performance evaluation are also discussed. The performance of Snake is also compared with other types of processor architectures. 1999 Elsevier Science B.V. All rights reserved.

This is because area processing with 3 3 mask is commonly used in many Low-level image processing operations usually involve image processing applications [5,9]. This is particularly simple and repetitive operations over the entire input images true for the image processing algorithms developed for [1–
