Abstract

The design complexity increased in SoC design that the ever increasing amount of logic that can be placed onto a single silicon die is driving the development of highly integrated SoC designs. For reducing this complexity, that high performance and low latency is required in on-chip bus. AMBA AXI protocol is an advanced microprocessor system bus interface and is an enhanced bus protocol of the existing advanced high-performance bus (AHB). In AXI in SoC, the interconnected functional blocks can be choosed based on matching of its addresses without using any priority policies.In this, the arbitration is proposed without using priority policies. Area and time delay will be reduced by using this bus matrix in the applications from that data speed can be increased with frequency.

Keywords

Abstract

Automatic Number Plate Recognition (ANPR) is an image-processing technology and an important field of research that identifies vehicles by their number plates in which the number plate information is extracted from vehicle's image or from sequence of images without direct human intervention. ANPR consists of 4 phases: - Preprocessing, number plate extraction, character segmentation, character recognition. This paper presents an efficient approach for number plate extraction from preprocessed vehicle input image using morphological operations, thresholding, sobel vertical edge detection and connected component analysis. The input image is firstly preprocessed using iterative bilateral filter and adaptive histogram equalization.
