High-Speed Data Acquisition With the Linux I/O Framework - Lars-Peter Clausen, Analog Devices

Sign up or log in to save this to your schedule and see who's attending!

The Linux IIO (Industrial IO) data converter framework has so far only supported low-speed converter devices (samplerate < 50kHz). From a framework point of view it is desirable though to handle low-speed and high-speed converter devices via the same (or a very similar) interface as this will allow sharing the supporting infrastructure. This talk will discuss the design challenges of adding support for high-speed data acquisition devices (with sample rates up to multiple GHz) to the IIO framework and how these challenges have been addressed. It will give an introduction to the new APIs (both kernel and userspace) that have been added to the IIO framework to accommodate the requirements of high-speed converters. The talk will also include an overview of the tools that have been developed around this new APIs.
