RapidIO Controller with V4.1 Support

Overview

Mobiveil's RapidIO Controller solution (GRIO) is a highly flexible and configurable IP. The Mobiveil RapidIO Controller Solution can be used as a Host or device. The RapidIO Controller when used along with Mobiveil’s RapidIO to AXI Bridge (RAB) provides speed multi-channel DMA, Data Message and Data streaming functionality to match the bandwidth requirements of the RapidIO interface.

The Mobiveil RapidIO Controller is a simple, configurable and layered architecture, independent of applications, implementation tools or target technology. The controller architecture is carefully tailored to optimize latency, power consumption, and silicon footprint, making it ideal for cost and performance sensitive applications. The RapidIO solution provides highly scalable bandwidth through a configurable data path width and clock frequency.

The controller's simple, configurable and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology. Mobiveil solution allows the licensees to easily migrate among FPGA, Gate array and Standard cell technologies optimally. Its flexible backend interface makes it easy to be integrated into wide range of applications. Mobiveil solution provides highly scalable bandwidth through configurable lanes, widths and frequencies.
