• In this paper we present a design of a switch wrapper as a component of SNA (SoC Network Architecture), which is an efficient on-chip-network compared to a shared bus architecture in a SoC. The SNA uses crossbar routers to provide the increasing demand on communication bandwidth within a single chip. A switch wrapper for SNA is located between a crossbar router and IPs connecting them together. It carries out a mode of routing to assist crossbar routers and executes protocol conversions to provide compatibility in IP reuse. A switch wrapper consists of a direct router, two AHB-SNP converters, a controller and two optional interface socket modules. We implemented a SNP switch wrapper in VHDL and confirmed its functionality using ModelDim simulation. Also, we synthesized it using a Xilinx Virtex2 device to determine resource requirements: the switch wrapper seems to occupy appropriate spaces, about 900 gates, considering that a single SNA crossbar router costs about 20,000 gates.
