Evaluation and Design Space Exploration of a Time-Division Multiplexed NoC on FPGA for Image Analysis Applications

The aim of this paper is to present an adaptable Fat Tree NoC architecture for Field Programmable Gate Array (FPGA) designed for image analysis applications. Traditional NoCs (Network on Chip) are not optimal for dataflow applications with large amount of data. On the opposite, point to point communications are designed from the algorithm requirements but they are expensives in terms of resource and wire. We propose a dedicated communication architecture for image analysis algorithms. This communication mechanism is a generic NoC infrastructure dedicated to dataflow image processing applications, mixing circuit-switching and packet-switching communications. The complete architecture integrates two dedicated communication architectures and reusable IP blocks. Communications are based on the NoC concept to support the high bandwidth required for a large number and type of data

Adaptive FPGA NoC-based Architecture for Multispectral Image Correlation

An adaptive FPGA architecture based on the NoC (Network-on-Chip) approach is used for the multispectral image correlation. This architecture must contain several distance algorithms depending on the characteristics of spectral images and the precision of the authentication. The analysis of distance algorithms is required which bases on the algorithmic complexity, result precision, execution time and the adaptability of the implementation. This paper presents the comparison of these distance computation algorithms on one spectral database. The result of a RGB algorithm implementation was discussed

4 pagesInternational audienceAn efficient Network on Chip (NoC) implemented on Field Programmable Gate Arrays (FPGA) is proposed for the data communication of multispectral image analysis algorithms in an adaptive architecture. The architecture design is based on the linear effort property and reusable IPs. Multispectral image data are several types of data, different length values. According to the requirement of the multispectral image data communication, this NoC used Virtual Channels (VC) with packet-switching. Implementations on FPGA show that a NoC-based communication scheme provides a superior solution than classical point-to-point communication
