Allwinner R329 Smart Speaker Processor Features Arm China’s AIPU (Artificial Intelligence Processing Unit)
Allwinner R328 is a dual-core Cortex-A7 processor with 64MB or 128MB built-in RAM designed for low-cost smart speakers that was introduced last year and found into smart speaker sold in mainland China. According to a recent press release (in Chinese only), the company has now released a 64-bit update with Allwinner R329 dual-core Cortex-A53 processor equipped with dual HIFI4 DSP for audio post-processing and pre-processing, as well as Arm China’s AIPU (Artificial Intelligence Processing Unit) delivering up to 0.256 TOPS at very low power. There’s no product page for Allwinner R329 yet, so I extracted some specifications from the press release: CPU – Dual-core Cortex-A53 @ up to 1.5 GHz DSP- Dual-core HIFI4 DSP @ 400 MHz AI Accelerator – Arm China AIPU with 0.256 TOPS Built-in DDR RAM Audio Embedded second-generation VAD hardware 5x audio ADCs 2x audio DACs with 100dB SNR I2S and DMIC controller 5-1-channel and 7.1 […]
KDE Plasma Bigscreen for TVs and TV Boxes Offers a Linux Alternative to Android TV
KDE Plasma is a desktop environment initially developed for Linux Desktop PC or SBCs, but that’s also available on Linux phones with Plasma Mobile (previously known as Plasma Active). The developers have now decided to work on a version for the big screens with Plasma Bigscreen suitable for TVs and TV boxes and offering an open-source, Linux-based alternative o Android TV. Plasma Bigscreen is community supported, completely free and open-source, and offers an interface fairly similar to Android TV launcher. It is optimized for IR remote control use including (experimental) CEC support, as well as voice control through MyCroft open-source AI & voice assistant and Bluetooth or RF remotes with a built-in microphone such as WeChip G20 or W2, or a USB microphone. By default, Plasmas Bigscreen connects to Mycroft’s Home server, which uses Google’s STT (Speech to text) sending anonymized utterances to Google, but it’s also possible to switch […]
This Non-Invasive AI Temperature Screening System Checks Multiple Persons On-the-Fly
Yesterday, I had to go to the bank with the branch located in a building where they closed all doors except one in order to make sure all people were wearing masks, check their temperature, and let them wash hands with alcohol hand gel. Those are good preventive measures to slow the spread of SARS-CoV-2 virus, but in case many people visit a location that’s also time-consuming. I’ve just come across a system that should speed up the process, as it can check forehead temperature of people as they walk by, using a camera and artificial intelligence for face detection, and an IR camera/thermometer to report temperature. Remote AI temperature screening system specifications: SoC/Memory/Storage – Don’t know, but I would not be surprised if it was based on RK3399 since Rockchip often promotes AI use cases for this processor. External Storage – MicroSD card, USB drive Video Output- HDMI 2.0 […]
