Design of Network on Chip (NoC) Computing Node for Mesh Topology using Soft-core NIOS-II Processor

Abstract

Paper discusses the design of computing node for Mesh topology-based Network on Chip (NoC) platform. The computing node has a capability of processing and routing data over four I/O port switch. Mesh topology is popular due to scalability and its simplest form. The platform is design for (N x N) computing nodes, where each node has soft-core based ‘NIOS-II’ processor. Each computing node has four-way switch East, West, North, South and one local port. The Mesh topology uses static look-up table optimized using proper routing algorithms. The lookup table information is used by Virtual Circuit Interface (VCI) of the switch node to forward the packets using combination of priority based round robin diagonal propagation scheduling algorithm. The design of computing node is generated using – Quartus-II ALTERA software and simulated for functional simulation. Such platforms are popular for data parallelism having applications in Smart sensors.

Industrial Image Enhancement Method Based on Cloud Edge Fusion

“…As shown in Figure 2, the wide value output port is added in SPOC, and the wide value is flexibly controlled through NIOSII [17] to achieve the best edge detection effect. Different from the median filter denoising algorithm, the edge detection algorithm selected in this paper is very simple, but it can be completely applied in the process of industrial image edge detection.…”
