40Gb/s RapidIO switches to boost computing performance

Seeking to meet the taxing performance requirements of advanced system architectures for wireless, embedded, and computing infrastructures, Integrated Device Technology, Inc. and eSilicon Corp. signed up for RapidIO collaboration to develop 10xN switches that operate at 40Gb/s per port.

The speed advantage is about staying a few steps ahead of mushrooming data usage tied in with the burgeoning use of portable devices.

"Advancements in interconnect are essential for the continued evolution of communications infrastructure," said Gregory Waters, CEO of IDT. "Our existing RapidIO switches are designed into virtually every 4G base station in the world. But the next generation of base stations and C-RAN is on its way, demanding higher performance than ever before."

Under the programme, RapidIO 10xN switches will offer an optimal combination of low 100ns latency, and scalability to greater than 4 billion nodes in a network. They will be especially useful in advanced base station platforms such as LTE-Advanced (LTE-A), C-RAN, and 5G, but will also find use in emerging architectures such as base stations co-located with high-performance computing platforms.

IDT's production 20Gbit/s per port switches are currently the de facto interconnect standard for the clustering of DSPs, microprocessors, and ASICs in existing 3G and 4G base stations deployed worldwide. The companies will build on this current production switch and bridge portfolio with a plan to make their first jointly developed products available in the second half of 2015.
