Why Serial RapidIO Gen2
Serial RapidIO
®
interconnect switches have become the standard in wireless infrastructure, video and
military/critical embedded systems. RapidIO Gen2 builds on the successful penetration of RapidIO 1.3
in these applications, where connecting large clusters of peer-to-peer processing elements is the
preferred architecture.
RapidIO Gen2 provides interconnect speeds of 5 Gbaud and 6.25 Gbaud, doubling the speed of RapidIO
1.3. This increase enables the deployment of next-generation systems using higher processor speeds and
allows for the aggregation of a larger number of processors while keeping up with real-time performance
needs. Switches based on the RapidIO Gen2 specification also minimize end-to-end system latencies and
feature deterministic system throughput.
The IDT RapidIO Gen2 family supports switching and IP solutions as well as bridging options to other
interconnect protocols for heterogeneous system solutions.
Applications that benefit from RapidIO Gen2
Wireless baseband, video and military/critical embedded systems applications deploy large clusters
of peer-to-peer ASICs, FPGAs and DSPs and are ideal candidates for RapidIO Gen2. These applications
are increasingly driven by performance demands that require ever larger and more powerful clusters
of processing elements.
3G and 4G Wireless
Pervasive broadband everywhere through 3G high speed packet access, 3G LTE and WiMax
Supports more subscribers per base station with higher data rate and service per subscriber
Handoffs at higher speed supports broadband mobility up to and exceeding 100 km/h
Increases performance of backplanes
Reduces cost by running less links of long traces
Allows better MIMO and advanced antenna systems algorithms within the system

IDT RapidIO Gen2 Intellectual Property (IP)
As part of its RapidIO Gen2 portfolio, IDT offers endpoint IP which allows DSPs, FPGAs, 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.
Texas Instruments™ has already adopted this IP in its next generation DSP program and will support
RapidIO Gen2 with out-of-the-box interoperability with IDT RapidIO Gen2 switches. IDT RapidIO Gen2
endpoint IP will work seamlessly with all silicon tested pre-silicon with the RapidIO Trade Association’s
bus functional model, and post-silicon with RapidIO Interoperability Lab (RIOLAB™) certified devices.
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.
