CES 2024: Creating a frugal code in embedded software

At CES 2024, a French startup is presenting the notion of frugal code in embedded software by identifying and quantifying the optimization potential of the code. WedoLow, a spinoff from three research laboratories—IETR, INSA, and Inria in Rennes, France—will demonstrate how its automated software solution works for automotive applications ranging from advanced driver assistance systems (ADAS) to autonomous driving (AD) to in-vehicle infotainment systems.

WedoLow claims that its solution addresses complexity in embedded software by diagnosing and checking the code rapidly throughout the development process. That’s how it ensures if the code is fully optimized and if gains can be obtained in terms of speed of execution or energy consumption.

Complexification of code in embedded software

At a time when applications are becoming larger and codes increasingly voluminous and complex, embedded systems are obviously no exception. That inevitably complexifies the work of developers, who now face a growing risk of delays with consequences for the efficiency and performance of their applications.

According to a 2020 survey from Sourcegraph, 51% of developers say they have more than 100 times the volume of code they had 10 years ago. Furthermore, 92% of developers say the pressure to release software faster has increased.

Take the case of the automotive industry, where cars have 200 million lines of code today and are expected to have 650 million by 2025. According to a McKinsey report titled “Outlook on the automotive software and electronics market through 2030,” the automotive software market is already worth more than 31 billion dollars and is forecast to reach around 80 billion in 2030.

The use of embedded software in the automotive sector has been constantly increasing since the introduction of anti-lock braking system (ABS) more than 40 years ago. So, gains in embedded software’s speed of execution and energy consumption will result in more responsive systems and longer battery life, which are crucial aspects for electric and autonomous mobilities.

How software works

WedoLow claims that its beLow software suite enables developers to understand the structure of a code and identify the parts that can be rewritten to generate more efficiency and performance. It’s enabled by optimization techniques that identify and quantify the potential optimization of the code at any stage of its development.

They build a line-by-line or function-by-function optimization strategy and obtain an optimized code rapidly and automatically. For example, WedoLow quotes a 23% gain in execution speed on the filtering of signals emitted by sensors on a road vehicle transmission system. Next, it helped achieve a 95% gain in execution speed on the processing of data and filtering of signals emitted by different sensors in battery management system (BMS) software.

Besides embedded software, WedoLow also aims to address the hosted software segment for server and cloud applications. Here, the French upstart conducted a test with an aerospace group on the processing of satellite images, reducing the software’s energy consumption by 18%.

WedoLow is presenting its frugal code solution at CES 2024; product launch is scheduled in the second quarter of 2024.
