Serial Bus Test: FB-DIMM, RapidIO, Quick Path, HyperTransport

The need to relieve throughput bottlenecks in computing and communications, together with the development of low cost, high speed CMOS technology, has caused the move to high speed (›1.5 Gb/s) serial buses. Fully Buffered DIMM is an evolving standard for fast access to large amounts of RAM for servers. RapidIO is an open-standard, switched fabric designed for developers of wireless infrastructure, edge networking, storage, scientific, military, and industrial equipment. Quick Path and HyperTransport are competing to be the next generation front side bus for processor interconnect applications. All of these have serial data rates that are firmly in the microwave arena, requiring significant attention to signal integrity.
