Superior Architecture
The GDA RapidIO-AMBA AXI Bridge (RIO-AXI Bridge) is a highly flexible and configurable IP with a RIO interface on one side and an AXI interface on the system side. The Bridge has been architectured to interface with a RapidIO controller used as a Host or device. The RIO-AXI BRIDGE uses high speed multi-channel DMA and Message controllers to match the bandwidth requirements of the RIO solution.
The GDA RIO-AXI Bridge 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 RIO-AXI BRIDGE solution provides highly scalable bandwidth through a configurable data path width and clock frequency,
Most Thoroughly Verified and Interoperable Design
The GDA RIO-AXI BRIDGE is an exhaustively verified solution tested with high coverage design specific as well as random tests. The IP is verified with RapidIO Trade association verification IP and the verification environment can be configured to run with all the major simulators. The reusable block level verification environment and the formal verification methodology enhance the quality of verification process and add more confidence to the design verification
The GDA RIO-AXI Bridge solution leverages years of experience in creating reusable IP solutions for Ethernet, Hypertransport and PCI Express technologies. The expertise in creating those system validated solutions with RTL, synthesis,
simulation, board and software elements ensures delivery of lower risk, compliant and interoperable solution.

Ease of Integration
The GDA RIO- AXI Bridge design is fully synchronous and adheres to standard synthesis, test insertion and physical design practices. The solution allows licensees to easily migrate among COT, FPGA, Gate array, structured ASIC and Standard cell technologies
Superior Support
The RIO-AXI BRIDGE solution comes with a superior support model that offers round the clock telephone, email, web based support and free code updates during the support period. Support documents including a data sheet, design guide, verification guide, synthesis guide and application notes are also offered. To build a full-system solution the GDA partner eco-system provides access to additional components such as verification IP, PHYs and related design services.
