His innovative work has led to the development of two patents that enhance computational efficiency in these areas.

Latest Patents

Raghu Sastry holds 2 patents. His latest patents include a VLSI circuit structure for determining the edit distance between strings. This invention computes the minimum cost of editing operations needed to convert one string into another. The circuit structure is designed for approximate string matching with variable edit costs and does not impose constraints on the lengths of the strings being compared. It utilizes simple basic cells and requires regular nearest-neighbor communication, making it suitable for VLSI implementation.

Another significant patent is for VLSI architectures for polygon recognition. This invention identifies unknown two-dimensional contours as corresponding to known contours. The architecture comprises a systolic processing system with matrix element processing elements (MEPEs) and feasible match processing elements (FMPEs). The MEPEs receive inputs of edge length ratios and threshold values, determining dissimilarity values for pairs of edges. The FMPEs then identify feasible matches, delivering outputs that indicate the longest number of consecutive edges for which matches have occurred.
