NoC is actively being studied recently in order to overcome the limitations of shared-bus architecture. We proposed an NoC architecture which employs a buffer that plays a similar role of a proxy server in a computer network to enhance the communication efficiency of NoC architecture. In the proposed NoC architecture, whenever the master has a difficulty in communicating with the slave directly, the master communicates with the proxy server which is able to communicate with the slave on behalf of the master. With the proposed scheme in NoC, we can increase the speed and the bandwidth of communication channel. The experimental results showed that overall communication efficiency was significantly improved by sending the packets to the proxy server rather than holding them in the switch buffer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
