Breker Tests Multicore

Earlier this year we were introduced to Breker, a company that generates C tests for stressing SoC architectures and verifying that things work even with bizarre corner code that someone writing directed tests might not think to create.

The original version supported a single CPU along with all of the surrounding circuitry. They have recently announced their multicore version. While this might sound like simply a matter of being able to run their previous tests on multiple CPUs, it’s far from that.

Multicore brings with it a whole slew of new things to go wrong. There may be bus clashes as multiple CPUs decide they’re in charge. You have resource contention and race conditions. There’s cache coherency – a deceptively complex architectural element required only for multicore.

All of these potential issues require tests that simply don’t exist for a single-core system. So moving to multicore is more than just about adding another CPU; it means developing a whole new set of test scenarios. So beyond just handling multiple CPUs, the new Breker tool version covers these multicore-specific issues.

You can find out more in their release.

Sensor Technologies Here to Stay: Post-pandemic

Sponsored by Infineon

Today sensor technology has become integral to our everyday lives. And in the future, sensor technology will mean even more than it does today. In this episode of Chalk Talk, Amelia Dalton chats with David Jones from Infineon about the future of sensor technologies and how they are going to impact our lives in the post-pandemic world. They investigate how miniaturization, built-in antennas in-package and the evolution of radar technology have helped usher in a whole new era of sensing technologies and how all of this and more will help us live healthier and happier lives.
