Design of Network Adapter Compatible OCP for High-Throughput NOC

Abstract

Network adapter is one of the most important components of NOC which is recommended to be used in present and future SOCs. In this paper, a network adapter compatible with OCP interface protocol is designed to enable the integration of IP cores from different providers into an on-chip interconnection network. In order to tradeoff communication performance with complication, the design of network adapter is based on a single global address space and supports burst transmission and virtual channel technology. With the goal of reducing transport latency, the processes of encapsulation and decapsulation are executing simultaneously with packet transmitting and receiving. Considering the simulation result, the network adapter presented in this paper gets satisfactory performance.
