Abstract: The network-on-Chip (NoC) design is the modern development in communication as the integration of the multiple network blocks in a single chip. Before the NoC, system on chip (SoC) was implemented. Development in the day to day the features were added to overcome the SoC like potential of the system on chip, operation frequencies, wiring congestion and size of the chip etc., as the SoC has the long sensitive path which shows the impact on the size of the chip. In wiring congestion: Routing a particular data with SoC requires lot of wirings. Coming to the NoC also developed in packet transferring from source to destination. Serial communication were first used to transfer as it take much time to transfer the data packets from the source to destination to overcome the serial path communication, parallel communication is used. In Parallel communication the packets are transferred from source to destination at a time. To improve the packet transfer in network many techniques are used like mesh topology, tree topology etc. The existing system will supports only the mesh topology and one to many packet transfer. In the proposed system, the new parallel multicast which uses the Globally Asynchronous and locally Synchronous Network on Chip (GALS NoC) that includes both Synchronous and Asynchronous Transmission with a slight change in IPM and OPM Architecture to support both synchronous and asynchronous transmission and reception of data packets. It has several advantages like it supports efficient many-to-one traffic, it is suitable for any topology and has improved Throughput.
