s-link, for "simple link interface", is a high-performance data acquisition standard developed at cern for collecting information from particle accelerators and other sources. unlike similar systems, s-link is based on the idea that data will be collected and stored by computers at both ends of the link, as opposed to a "dumb" devices collecting data to be stored on a "smart" computer. having a full computer at both ends allows s-link to be very thin, primarily defining the logical standards used to feed data at high speed from the motherboards to the link hardware interfaces.
