py-videocore6 Raspberry Pi 4 GPGPU Python Library Leverages VideoCore 6 GPU

py-videocore6 Raspberry Pi 4 GPGPU

Raspberry Pi 4 SBC was released at the end of June with a new Broadcom BCM2711B SoC that also includes VideoCore 6 (VC6) GPU for 2D and 3D graphics, and that could also be used for general-purpose GPU computing (GPGPU). In the past we’ve seen companies such as Idein leveraged VideoCore 4 GPGPU capabilities in Raspberry Pi 3 / Zero to accelerate image recognition, and they released a python library (py-videocore) for that purpose. The problem is that the VideoCore 6 GPU found in RPi 4 is quite different than the VideoCore 4 GPU in earlier versions of the Raspberry Pi Foundation board as forum member phiren explains: I’ve been looking though the open source drivers and here are some of my observations: vc6 is clearly derived from vc4, but it is significantly different. vc6 is only a slight extension over vc5 The QPU pipeline stays mostly the same, you still have an add ALU and a multiply ALU and …

Nubix Edge-native Tiny Containers for IoT Apps Released For Raspberry Pi and BeagleBone SBCs

Nubix.io Tiny Container Architecture

Nubix has just launched the developer edition of its edge-native tiny containers for IoT application development and analytics that target microcontrollers and single-board computers such as Raspberry Pi 3/4 and BeagleBone Black. Typical cloud solutions such as Docker are often too large with tiny IoT devices, and to solve these issues, Nubix tiny containers are sized in kilobytes, instead of megabytes, or about 100 times smaller than a Docker container, in order to be small enough to run at the edge. Nubix.io provides access to a library of sensors, analytics and tiny services that leverage open source languages and pre-packaged functions to easily create IoT applications in a few minutes. Analytics is commonly done in the cloud, which may cause issues in environments with limited or intermittent connectivity, so to solve this issue, Nubix provides analytics functionality directly on the IoT device, eliminating the latency, bandwidth, connectivity and cost constraints of moving data from a large number of connected sensors/nodes. …

Raspberry Pi 4 Digital Signage Solution Supports 4K HEVC Video and Dual Display Setups

Raspberry Pi 4 4K Digital Signage

4K H.265 & dual-display digital signage for Raspberry Pi 4 The Info-Beamer, the company that started as a for-fun project at a hacker conference and turned into a now growing business has developed the first Raspberry Pi 4 OS that can use the HEVC (H.265) decoding system and support dual-display setups. The latest info-beamer hosted version 11 (aka hosted 11) is designed for 4K video quality digital signs, and the two HDMI ports on the Raspberry Pi 4 can be used simultaneously for mirrored output on two displays or span two video displays on digital signs. The company has reported that this solution can work on a video wall, like the info-beamer magic video wall. Previous Info-Beamer Previously there was an info-beamer hosted 10 released in February 2019 and that version is still applicable if wanted.  All versions of Raspberry Pi are still supported but the OS 11 release focuses on Pi 4. Demo Installation Info-beamer is offering a free …

Broadcom BCM7218X STB SoC Comes with AV1 Hardware Decoding, WiFi 6

Broadcom-BCM7218X STB SoC AV1 Codec

CNX Software first covered AV1 open-source, royalty-free video codec aiming to compete against H.265 and succeed VP9 in 2016. I also tried the reference implementation and both encoding and decoding were really slow at that time and an AMD FX8350 powered computer would only achieve 0.36 fps encoding on a 352 x 288 video, while decoding was much faster at over 1,000 fps. This was really early work, and the final AV1 specifications were only released in March 2018, before companies like YouTube and Netflix started to publish AV1 video samples, and now I’ve noticed the former is sometimes streaming videos using AV1 codec on desktop computers and laptops. This still relies on software decoding, and most Arm platforms and entry-level level Intel computer may not be able to handle AV1 decoding, so hardware decoding will eventually be required, especially on battery-operated devices since it will consume much less power. Which brings me to Broadcom BCM7218X, which is the first …

PiCAN3 Board for the Raspberry Pi 4 adds CAN Capabilities plus a Real-Time Clock

PiCAN3 CAN Bus Board for Raspberry Pi 4 with 3A SMPS And RTC

Copperhill Technologies has recently announced the release of its PiCAN3 CAN-Bus Board for the Raspberry Pi 4. The PiCAN3 adds Controller Area Network capabilities plus a real-time clock to the new Raspberry Pi SBC. The Controller Area Network (CAN Bus) is a robust and common industrial communication bus used mostly in the automotive industry. CAN supports long travel distance, medium communication speed, and quite reliable. One of the most significant advantage with CAN-BUS is that it connects any number of ECUs (or microcontrollers) in your car through the two-wire bus, CAN High and CAN Low, reducing the weight of wires that could be gained by using point-to-point communication between ECUs. CAN bus is one of five protocols used in the on-board diagnostics (c)-II vehicle diagnostics standard. Although it is popular in the automotive industry, the Raspberry Pi doesn’t provide an off the shelf support for working with CAN-BUS. Users interested in trying out CAN will have to result to using HATs like the …
