IDT offers RapidIO Gen2 intellectual property (IP)

As part of its RapidIO Gen2 portfolio, IDT offers endpoint intellectual property (IP) which allows DSPs, ASICs and microprocessors to easily access RapidIO networks. By using IDT RapidIO Gen2 IP, customers are assured of interoperability with the number one supplier of RapidIO switches: IDT.

IDT RapidIO Gen2 endpoint IP works seamlessly with all silicon in the ecosystem that has been tested pre-silicon with the RapidIO Trade Association’s bus functional model and post-silicon with those that have achieved RapidIO Interoperability Lab (RIOLAB) certification.

Customers using the IDT RapidIO endpoint IP are supported by the IDT RapidIO system modeling tool, allowing them to proactively architect RapidIO networks with a variety of traffic scenarios, port widths and speeds in advance of board design. This allows customers to optimally select systems configuration based on overall performance. In summary, IDT remains committed to ensuring a robust RapidIO Gen2 ecosystem for high performance wireless, military and video systems.
