Rockchip roadmap reveals RK3576 and RK3506 IoT processors, Linux 6.1 SDK

The Rockchip RK3588 processor may remain the most powerful processor from the company for a while as an updated Rockchip IoT processor roadmap reveals the new RK3576 octa-core SoC and RK3506 tri-core Cortex-A7 chip, as well as a Linux 6.1 SDK to be released in Q4 2023. With the limited information we have, the Rockchip RK3576 looks to be a cost-down version of the RK3588 processor with eight cores, a 6 TOPS NPU, a 4K video codec, as well as PCIe and USB-C interfaces. Strangely the Rockchip RK3582 that should serve a similar purpose is not showing up in the roadmap. [Update: The RK3576 is indeed a lower-cost SoC but features four Cortex-A72 and four Cortex-A53 cores instead as per the comparison table reproduced below: That also means we now have the RK3576 specifications (some obtained from another document too): CPU Octa-core Arm processor with 4x Cortex-A72 cores at 2.2 […]

Generative AI on NVIDIA Jetson Orin, Jetpack 6 SDK to support multiple OSes

NVIDIA has had several announcements at ROSCon 2023 related to robotics & embedded with highlights including generative AI on the NVIDIA Jetson Orin module and the Jetpack 6 SDK will be released next month (November 2023) with supports for Ubuntu as usual, but also other operating systems and platforms such as Debian, Yocto, Wind River, Redhawk RTOS, and Balena. Generative AI on NVIDIA Jetson Orin There’s been a lot of hype in the last year about generative AI thanks to services such as ChatGPT, Google Bard, or Microsoft Bing Chat. But those rely on closed-source software that runs on powerful servers in the cloud. As we noted in our article about the “AI in a box” offline LLM solution there are some open-source projects such as Whisper speech-to-text model and Llama2 language models that could be run on embedded hardware at the edge, but as noted by some readers platforms […]

Bluetooth NLC (Networked Lighting Control) fully standardizes Bluetooth light bulbs

Bluetooth NLC (Networked Lighting Control) is a full-stack standard for wireless lighting control from the Bluetooth SIG that will enable multi-vendor interoperability, improve ease of deployment, and offer greater scalability. Bluetooth light bulbs have been around for many years, at first using Bluetooth LE (Radio Layer) and then adding Bluetooth Mesh (Network Layer) to the mix, but there were always some proprietary bits to the software stack, and Bluetooth NLC removes all those with a complete standard for lighting control that further adds Device Profiles specific to his use case. Bluetooth NLC still relies on Bluetooth Low Energy and Bluetooth Mesh, but adds the following NLC Device Profiles at the Device Layer defining the requirements for a range of devices/features: Ambient Light Sensor Basic Lightness Controller Basic Scene Selector Dimming Control Energy Monitor Occupancy Sensor You’ll find the specifications for each profile on the Bluetooth website. While the announcement was […]

Cadence Neo NPU IP scales from 8 GOPS to 80 TOPS

Cadence Neo NPU (Neural Processing Unit) IP delivers 8 GOPS to 80 TOPS in single core configuration and can be scaled to multicore configuration for hundreds of TOPS. The company says the Neo NPUs deliver high AI performance and energy efficiency for optimal PPA (Power, Performance, Area) and cost points for next-generation AI SoCs for intelligent sensors, IoT, audio/vision, hearables/wearables, mobile vision/voice AI, AR/VR and ADAS. Some highlights of the new Neo NPU IP include: Scalability – Single-core solution is scalable from 8 GOPS to 80 TOPS, with further extension to hundreds of TOPS with multicore Supports 256 to 32K MACs per cycle to allow SoC architects to meet power, performance, and area (PPA) tradeoffs Works with DSPs, general-purpose microcontrollers, and application processors Support for Int4, Int8, Int16, and FP16 data types for CNN, RNN and transformer-based networks. Up to 20x higher performance than the first-generation Cadence AI IP, with […]

e-con systems See3CAM_24CUG USB 3.1 global shutter camera review

e-con Systems See3CAM_24CUG a full HD color global shutter USB 3.1 Gen 1 camera based on an Onsemi AR0234CS CMOS image sensor capable of capturing moving scenes at up to 120 fps. This global shutter camera is especially useful for robotics and other applications that may require a high frame rate such as Automatic Number Plate Recognition (ANPR), Autonomous Mobile Robots (AMR), gesture recognition, drones, barcode scanners, factory automation, conveyor monitoring cameras, and traffic monitoring systems. e-con Systems sent a See3CAM_24CUG USB global shutter camera sample to CNX Software for review. I’ll go through an unboxing before testing in Ubuntu with both an AMD Ryzen 7 2700U laptop and a Raspberry Pi 4 single board computer. It happens to be based on the same sensor as the e-CAM20_CURB camera for Raspberry Pi 4 that we reviewed last year.
