Solving the Challenges of the Evolution Drive from Bluetooth LC3 to LC3Plus Codecs
Speakers: Michael Rougeux, Director of Software Engineering, T2 Labs, and Graham Wilson, Sr. Product Marketing Manager, Synopsys
In January of 2020, the Bluetooth SIG announced that the Bluetooth LE Audio standard will include the Low Complexity Communications Codec (LC3), with several companies announcing available solutions for the Bluetooth LC3. The Bluetooth LE Audio standard with LC3 is expected to gain large amounts of traction in the industry, enabling the next-generation of Bluetooth audio solutions. Technology leaders in the industry are also looking at the next evolution step of the Bluetooth LC3 with the LC3 Plus codec specification. LC3Plus comprises all features of the Bluetooth LC3 plus an advanced PLC for transmission robustness, lower delay modes down to 5ms at a 2.5ms packet size, and higher resolution audio modes. LC3Plus enables a new range of applications as well as technical challenges. This joint presentation between T2 Labs and Synopsys details the new target applications of LC3 and LC3Plus and the technical challenges for proposed solutions of LC3 and LC3Plus codecs.

Trends in Machine Learning for Edge Applications
Speaker: Pierre Paulin, Director of R&D, Embedded Vision, Synopsys
Embedding computer vision and deep learning at the edge remains challenging today because of 1) huge computational and memory requirements, and 2) the accelerating pace of innovation for algorithms that perform modern vision and sensing tasks. CNN graphs particularly are rapidly evolving to improve the accuracy and speed of learning and inference. Mapping vision and deep learning algorithms to low-power embedded platforms is challenging because they are often very demanding on compute, bandwidth, and accuracy.
In this presentation, we will discuss the latest trends in machine learning for edge applications, including emerging models like EfficientNet and new techniques like Transformers. We will review the key challenges and opportunities for embedded implementation with a focus on new techniques for bandwidth optimization. This presentation will also explain how the latest trends are shaping enhancements to the DesignWare EV Embedded Vision Processor IP family.

A Brief History of Time – of a Bluetooth Controller
Speaker: David Peavey, System Engineer, Intel
The Bluetooth Core Specification has undergone several rapid changes over the past two decades. The addition of Bluetooth low energy in 2010 further accelerated the evolution of the technology. Bluetooth is widely used today in PCs, mobile phones, headsets, wearables, and a myriad of IoT devices. As expected with any immensely successful technology in an increasingly competitive landscape, the bar is being raised on performance and low power consumption requirements for each successive product generation. The Bluetooth controller – considered the “brains” of the Bluetooth system – has constantly adapted and kept up with the requirements. This paper traces how the growth of the Bluetooth specification, use cases, and Key Performance Indicators (KPIs) evolved the controller hardware architecture over the years. Despite the ever-increasing performance and use case demands, the march towards lower and lower power consumption is relentless.
