Design and implementation of network interface compatible OCP For packet based NOC

The idea of using on chip packet switched networks for Interconnecting a large number of IP cores is very practical for designing complex SoCs since it gives possibility of not only reusing IP cores but also the interconnection infrastructure. However, the real effort and time in using these Networks on Chip (NoC) go in developing interfaces for connecting cores to the on-chip network. Standardization of interfaces for these cores such OCP [1] can speed up the development process.In this paper, we present our work of developing a Network Interface for an on-chip network that support OCP IP standard. We chose a range of IP OCP that need to support basic and precise burst mode extension for design an effective. Any cores IP having this configuration can reuse this network interface. Finnaly we will present a comparative study between two Master Network Adaptator and tow Slave Network Adaptator that use respectively handshake and credit based control flow.
