A Design of Network Interface Applied to Multi-core DSP Off-chip Extension

The advantage of RapidIO in multi-core DSP interconnection is analyzed and a network on chip interconnection architecture applied for multi-core DSP application is proposed in this paper. A network interface architecture compatible of RapidIO protocol is designed and inplememented.We build up the functional simulation model of the network interface, based on which the throughput and extra time delay of the network interface is appraised.
