The RapidIO Interconnect Architecture, designed to be compatible with the most popular integrated communications processors, host processors, and networking digital signal processors, is a high-performance, packet-switched, interconnect technology. It addresses the high-performance embedded industry's need for reliability, increased bandwidth, and faster bus speeds in an intra-system interconnect. The RapidIO interconnect allows chip-to-chip and board-to-board communications at performance levels scaling to ten Gigabits per second and beyond.

GDA's RapidIO controller core (GRIO) is designed to meet the growing needs of the industry. The core's simple, configurable and layered architecture is independent of applications, PHY designs, implementation tools and, most importantly, the target technology. The hardware and software configurable features make the core suitable for use in multiple applications. The design targets embedded systems, telecommunication, networking and any application where high speed, low latency response, low pin counts, reliability and scalability are necessary.
