Abstract

A systemC model of a code-division multiple- access (CDMA) network-on-chip (NoC) is presented in this paper. The CDMA NoC modeled in this paper is a globally- asynchronous locally-synchronous (GALS) on-chip communication network which applies CDMA technique to transfer data among different network nodes concurrently. The presented SystemC model uses Transaction-Level Modeling (TLM) approach to model the asynchronous handshake processes for data transfers in the CDMA NoC. A performance- estimation method which bases on timing back-annotation is also presented for exploring the CDMA NoC performance under different configurations in a fast and efficient way. Finally, the performance estimation results of the CDMA NoC with different configurations and traffic patterns are presented.
