Low-latency interconnect supports both 4G & 5G

The 20Gb/s RapidIO Gen 2 interconnect enables the scaling of large pools of heterogeneous processors required for C-RAN, as well as mobile edge compute. These systems are able to scale from simple architectures with a few processors, to large systems supporting many users and processors connected via a 100ns latency RapidIO fabric.

Sean Fan, Vice President and General Manager, Interfaces & Connectivity Division, IDT, commented: “We’re excited by the production deployment of Fujitsu’s cellular base station systems based on IDT’s RapidIO technology.  This strongly demonstrates RapidIO’s ability to support large clusters of processors required not only for C-RAN and Supercomputing at the Edge, but also other real-time processing systems such as those in high performance data analytics. RapidIO-based systems are solving a new paradigm of processing in this era of explosive growth of live streaming data and emerging applications such as video transcoding and analytics and machine-to-machine communications for safety and control functions in autonomous vehicles."

“A low-latency interconnect is one of the keys to building large scale systems. There are many similarities between C-RAN systems and high performance computing, with the need for low latency any-to-any inter processor communication. With RapidIO technology connecting 100% of 4G base stations and now its emergence in the new C-RAN deployments, we are excited to collaborate with IDT on the path to applying this technology for the OCP high performance compute projects,” said Corey Bell, CEO, Open Compute Project (OCP).

IDT’s next-gen RapidIO 10xN technology supporting 40Gb/s with a roadmap to 100Gb/s will provide wireless infrastructure systems the technology to evolve to 5G and beyond. RapidIO’s performance, scalability, and energy efficiency will enable the future of continued convergence of communications and high performance compute, driven increasingly by the demands of mobile access.
