Doing More with Less (Hardware, That Is)

By using a system of modular hardware, companies are able to combine the benefits of homegrown flexibility with COTS reliability and support, thus harnessing the full power of flexible, modular I/O. They can select among multiple-channel modules designed for the signal types of interest and configure flexible instrumentation solutions using software. [More…]

Data Acquisition Systems Track Signal Processing Technology

Signal processing systems are crunching ever larger amounts of sensor data, in turn demanding data acquisition and recording systems that
can keep pace. Switched fabric interconnect and FPGA-based processing
make possible the development of high-performance data acquisition
and playback systems that reuse existing components and provide
application-specific tailoring where it is really needed. [More…]

Shared Memory Network Targets Video-Centric Data Acquisition

The entry of real-time video data capture technology into data acquisition and distribution systems is challenging design engineers to maintain the high throughput and low latency needed by large video streams. Distributed shared memory networks not only fulfill those needs, but also allow remote placement of the data processing system. [More…]

Standardizing Digital IF Data Transfer with VITA 49

Intermediate frequency (IF) data normally passes between system elements in analog format over coaxial cables. VITA is developing a new interconnect standard for passing IF data between analog front-ends and DSP subsystems in a digital, link-agnostic format. [More…]

Data Acquisition Subsystems Getting Faster, Interface-Agnostic

More and more embedded applications rely on next-generation,
high-performance data acquisition subsystems to gather large
quantities of data at high speeds and convert it into usable form.
The use of switched fabrics, FPGAs and network topologies, along
with a move toward flexible interfaces and vendor interoperability,
are helping designers of these subsystems keep pace. [More…]

High Speed Sensors and Shared Memory

Getting data from sensors to processors at a sufficient rate involves buffering it in memory so it can be processed. Using multiple sensors with multiple processors in a shared memory scheme offers flexibility, load sharing and fault tolerance. [More…]
