The Serial RapidIO core supports the physical layer specification as defined in the RapidIO Specification Rev 1.2. The Serial RapidIO Physical Layer defines a protocol for packet delivery between Serial RapidIO devices and other devices, including packet transmission, flow control, error management and link maintenance protocols. The core supports one-lane high speed (1x mode) running at 1.0, 2.0 Gbps or a maximum of 2.5 Gbps. This Serial RapidIO core is optimized to support ORT82G5/ORT42G5 FPSCs.
