Chirp announced its support for Arm^® Cortex-A and Cortex-M based architectures, improving device-to-device connectivity on any Arm^®-based product with audio capabilities.

Chirp’s Arm SDK has benefitted from the DSP functionality of Arm's Cortex-M4 and Cortex-M7 processors to engineer a reliable data transfer solution sans being resource intensive, aiding connectivity and application logic to dwell on a single Arm core.

The SDK:

• Is a static library (approximately 740KiB in size) with a straightforward API for sending and receiving data by way of Chirp signals
• Integrates physical and data link layers of the data-over-sound OSI stack with other layers including encryption, application-specific protocols or end-to-end transmission/QoS that can go on top of the SDK if required

“By simplifying data-over-sound technology for Arm-based devices, we are able to extend our support of developers with a reliable data transfer solution and increase the footprint of data-over-sound as a cost effective and versatile capability to application connectivity,” said Chirp’s CEO, James Nesfield. “The demand for frictionless data exchanges between connected devices is growing constantly and we look forward to seeing our technologies work together to make communication between devices both simple and seamless for the end user.”
