In this work, we introduce an hybrid WiNoC, which judicially uses the wired and wireless interconnects for broadcasting/multicasting of packets. A code division multiple access (CDMA) method is used to support multiple broadcast operations originating from multiple applications executed on the multiprocessor platform. The CDMAbased WiNoC is compared in terms of network latency and power consumption with wired-broadcast/multicast NoC.
