Serial RapidIO is a communication protocol developed to ensure fast and reliable interconnection between the vendor's boards.
The basic idea behind Serial RapidIO is to enable communication speeds up to 25Gbps/lane (up to 100Gbps/port with a 4-lane port) while allowing the user to send a variety of different message s with CRC protection, retransmission on error, and virtual channels for quality of service. The specification also defines multiple forms of remote memory access and network interfaces, allowing the user to create a network of SRIO endpoints.
The SRIO IP-Core has been successfully tested at 2Gbps/lane (SBC003) and 8Gbps/lane (SBC002).
