The fight against the Coronavirus does not only take place in medical laboratories, but also in computing. Spectrum Instrumentation has announced that it has created a Software Development Kit (SDK) “Julia” to take on these challenges.

“Julia”, a relatively new software language, has surged in popularity as it handles huge amounts of data for vaccine development requires advanced tools.

The software delivers comparable speed and functionality to programming in C while also allowing scientific and numerical computing.

Scientific test

Spectrum Instrumentation, a manufacturer of advanced scientific test and measurement equipment, announced that it has created Jilia SDK for programming its full range of over 200 different digitizers, generators and digital I/O products.

A key feature of Julia is that it is designed for high-performance applications that require fast processing of data, like machine learning and scientific computing.

For example, libraries include optimized source C and Fortran code for linear algebra, random number generation, signal processing, and even string processing. Furthermore, Julia offers parallelism.

Command line

Call the desired script with a given number of cores and parallelise directly from a command line. Additionally, it is possible to send tasks to different threads, or run loops in parallel, directly from code.

The result is a language that offers similar speeds to C, while allowing coding that is more comparable to Python or MATLAB. Companies around the world use Julia in a wide range of applications. Some examples can be found here: https://juliacomputing.com/case-studies/

Julia and Spectrum Instrumentation make a perfect fit as the Spectrum products are ideal for acquiring or generating the fast electronic signals found in AI applications or robotics.

The company offers the most extensive range of digitisers for the acquisition of analogue or digital signals, in the DC to GHz frequency range, with high precision and dynamic range.

Signal generation

The digitisers are complemented by an extensive line-up of high-resolution Arbitrary Waveform Generators (AWGs). These products are perfect for control signal generation, waveform replay and simulation.

The products are available in a variety of form factors including tiny PCIe cards, which can plug directly into a PC, or LXI boxes that connect to a network or PC via Ethernet, plus PXIe modules for off-the-shelf installation into automated test systems.

Combining Julia with Spectrum Instrumentation products also helps to speed up processing and reduce latency. The Spectrum products offer ultrafast data transfers with a variety of different acquisition and generation modes (such as single, multiple, gated, and FIFO) which helps to optimise testing throughputs.

Spectrum products

It is a key benefit for situations that require fast decision making and it is one of the reasons why Spectrum products can be found working in applications involving autonomous vehicles, robotics, drones, imaging devices, medical appliances, and control systems.

Their general-purpose design means they can also be used with almost any sensor (accelerometers, transducers, photodiodes, detectors, MEMS, etc.) that is commonly found in AI machines.

As an example, Dr. Josef Höffner from the Leibniz Institute for Atmospheric Physics in Germany develops high-performance LIDAR (Light Detection and Ranging) systems to measure temperature and wind speed in the atmosphere.

High-speed signals

Now a Julia user says programmers perform complex data acquisition and control, with 30 high-speed signals, using three Spectrum Instrumentation cards, operating in closed-loop operation 24/7.

“Our laser makes 500 pulses per second and we have to calculate, in real-time, what has to happen next and adjust the controls. For that, we have to get the result quickly. That means fast electronics, fast evaluation, and then fast control of the hardware. We have found Julia offers a unique combination of speed and dynamic programming, simplifying the software development,” said the developer.

Firmware updates

The new SDK supporting Julia is available free of charge to all Spectrum customers. Spectrum products include an industry-leading 5-year warranty with free software and firmware updates for each unit’s lifetime. Additionally, customers get support directly from Spectrum’s hardware and software engineers.

Spectrum Instrumentation, founded in 1989, uses modular design to create a wide range of digitisers and generator products as PC-cards (PCIe and PXIe) and stand-alone Ethernet units (LXI).

In 30 years, Spectrum has gained customers all around the world, including many A-brand industry leaders and practically all prestigious universities. The company is headquartered near Hamburg, Germany, and known for its outstanding support that comes directly from the design engineers.
