Central to this demonstration is the Synaptics SL1620 System-on-Chip (SoC), running a Linux-based operating system. The SL1620 is engineered for embedded applications requiring robust processing capabilities, advanced artificial intelligence (AI) functionalities, and 3D graphics support. Its architecture includes a quad-core Arm® Cortex®-A55 CPU operating at up to 1.9GHz, an Imagination™ BXE-2-32 GPU, and support for dual displays via MIPI DSI interfaces. citeturn0search0
The prototype’s microphone array is integrated with AI-driven noise reduction algorithms, enhancing voice clarity by filtering out ambient noise. Users can manually select the desired audio beam or enable automatic beam selection, allowing the system to dynamically track and focus on the primary speaker. This functionality is particularly beneficial in environments such as home offices, call centers, or conference rooms, where multiple conversations may occur simultaneously.
The SL1620 SoC’s comprehensive feature set includes support for various peripherals, audio processing capabilities, and secure boot mechanisms, making it a versatile solution for diverse embedded applications. Its design emphasizes high performance per watt, catering to the demands of modern IoT devices that require efficient and secure processing. citeturn0search0
