7.24 Serial RapidIO (SRIO) Port
The SRIO port on the TMS320C6678 device is a high-performance, low pin-count interconnect aimed for embedded markets. The use of the RapidIO interconnect in a baseband board design can create a homogeneous interconnect environment, providing even more connectivity and control among the components. RapidIO is based on the memory and device addressing concepts of processor buses where the transaction processing is managed completely by hardware. This enables the RapidIO interconnect to lower the system cost by providing lower latency, reduced overhead of packet data processing, and higher system bandwidth, all of which are key for wireless interfaces. For more information, see the Serial RapidIO (SRIO) for KeyStone Devices User Guide (literature number SPRUGW1).
