CDMA interconnect is a new interconnect mechanism for future SoC. Compared to a conventional TDMA-based bus, a CDMA-based bus has better channel isolation and channel continuity. We introduce a new bus architecture called CT-Bus, which mixes and takes strengths of both CDMA-based and TDMA-based interconnect schemes. A CT-Bus gives designers the ability to cope with widely varying communication requirements. We propose a method and a tool to explore the mapping of heterogeneous traffic flows onto the CT-Bus. Simulation results on a multimedia mobile phone system show that traffic flows mapped onto a CT-Bus meet the latency requirements while the same traffic flows mapped onto a conventional TDMA-only bus violate these requirements.
