The RapidIO® Ecosystem
Markets Deploying RapidIO® Technology
RapidIO® components have been deployed in a wide range of industries and applications:
RapidIO Fabrics enjoy dominant market share in global deployment of cellular infrastructure 3G, 4G & LTE networks with over 45 million RapidIO ports shipped into wireless base stations to date. RapidIO Fabrics were originally designed to support connecting different types of processors from different manufacturers together in a single system.
This flexibility has driven the widespread use of RapidIO Fabrics in wireless infrastructure equipment where there is a need to combine general purpose, digital signal, FPGA and communication processors together in a tightly coupled system with low latency and high reliability.
For applications ranging from nanometer-accurate motion control to real-time image processing, RapidIO Fabrics deliver key performance metrics such as best in class switch cut through latency of ~100ns, lossless data flow, small footprint and lowest overall power consumption when compared to other fabric technologies.
Over the last several years, Aerospace and Military electronic systems have become increasingly network-centric, relying more and more on the quality of the data they receive from sensors on land, at sea, and in the air. These systems require high bandwidth combined with low latency to move the data quickly from chip to chip, box to box, and system to system.
RapidIO has solidified a dominant market position within intensive signal-processing applications like radar and sonar.
Offering peer to peer connectivity, low deterministic latency and high availability features such as High Availability/Redundant System Hardware (HARSH) profiles RapidIO technology provides the optimum solutions for sensor fusion challenges. RapidIO fabrics deliver highly reliable, fault tolerant performance to demanding safety critical applications.

RapidIO® Working Groups
The NGSIS Task Group will develop a space specific Part S specification as part of the RapidIO interconnect standard specifications. The purpose of the Part S specification will be to provide an industry and government agreed standard for intra-satellite physical and logical interconnects, based on the RapidIO interconnect standard that covers high and low-data rate use cases.
- UVM-based and other verification IP that can reduce overall verification effort
- Compliance checklists to simplify test plan development
- A verification community to help new members quickly and efficiently develop compliant RapidIO products
The RapidIO Software Task Group shall be responsible for developing the open source interface definitions and implementations using the “C” language under the Linux operating system for the following functionality:
- “Data Path Software” for high performance data transfers between RapidIO endpoints
- “Fabric Management Software” and “Command Line Interpreter” for RapidIO Fabric and Endpoint management
- Other functionality as necessary to support RapidIO systems development and deployment
The objective of the Marketing Working Group (MWG) is to establish a strategy that will accelerate adoption of RapidIO in the high performance embedded marketplace and that will result in broad deployment in the appropriate applications. We will accomplish this goal through a number of diverse marketing activities that involve competitive analysis, positioning, new member recruitment, user education, and promotion within the industry.
