Modular Mojo claims to be over 36,000 times faster than Python for AI workloads

Modular Mojo is a new programming language designed for AI developers that is said to combine the usability of Python with the performance of C with over 36,000 times the performance of Python on a matrix multiplication workload. Modular Mojo programming language was not in the initial plan of the company but came about when the company’s founders – who focused on building a platform to unify the world’s ML/AI infrastructure – realized that programming across the entire stack was too complicated and also ended up writing a lot of MLIR (Multi-Level Intermediate Representation) by hand. The “over 36,000 times speedup” claim comes with the matmul.py script performing a 128×128 matrix multiplication in Python with a throughput of 0.00215 GFLOP/s and another script doing 512×512 vectorized + parallelized matrix multiplication in Mojo at 79.636 GFLOP/s. The claim looks dubious and that’s odd they used different matrix sizes, but some are […]

Youyeetoo YY3568 devkit review – Part 1: Unboxing, specifications, and Android 11 testing

Youyeetoo has sent us a review sample of their YY3568 “Bundle 5” devkit with the Rockchip RK3568-powered YY3568 SBC, an 11.6-inch touchscreen display, a MIPI camera module, and all accessories required to get started. We were especially interested in using it to play with the 1 TOPS NPU in the Rockchip RK3568 in Linux, but we’ll start the Youyeetoo YY3568 review with an unboxing, some specifications, and a quick review with Android 11 before switching to Debian 10 in the second part of the review. Youyeetoo YY3568 devkit unboxing The YY3568 single board computer itself is comprised of a carrier board and a YY3568-Core board with a Rockchip RK3568 processor, as well as 8GB RAM, 64GB eMMC flash, and WiFi 5 and Bluetooth 5.0 module. The board is suitable for various applications from generic computing to video playback and AI workloads. YY3568 SBC specifications and hardware overview Youyeetoo YY3568 board […]

TRACEPaw sensorized paw helps legged robots “feel the floor” with Arduino Nicla Vision

Our four-legged friends don’t walk on tarmac the same way as they do on ice or sand as they can see and feel the floor with their eyes and nerve endings and adapt accordingly. The TRACEPaw open-source project, which stands for “Terrain Recognition And Contact force Estimation through Sensorized Legged Robot Paw“, aims to bring the same capabilities to legged robots. Autonomous Robots Lab achieves this through the Arduino Nicla Vision board leveraging its camera and microphone to run machine learning models on the STM32H7 Cortex-M7 microcontroller in order to determine the type of terrain and estimate the force exercized on the leg. But the camera is apparently not used to look at the terrain, but instead, at the deformation of the silicone hemisphere – made of “Dragon Skin” – at the end of the leg to estimate 3D force vectors, while the microphone is used to recognize terrain types […]

Banana Pi BPI-6202 industrial SBC features Allwinner A40i SoC, 24V DC input, RS485 interfaces

Banana Pi BPI-6202 “embedded single board computer” features the industrial-grade Allwinner A40i quad-core Cortex-A7 processor with industrial temperature range and long life cycle, 2GB DDR3, 8GB eMMC flash, M.2 SATA slot, and more. That’s the second Allwinner A40i board from Banana Pi since the company launched the Banana Pi BPI-M2 Ultra SBC last year, but the new embedded SBC looks to be better suited for industrial applications with features such as dual Ethernet, an RS485 + RS232 terminal block, 24V DC input, and a -40 to +60°C operating temperature range. Banana Pi BPI-6202 specifications: SoC – Allwinner A40i quad-core Arm Cortex-A7 processor @ 1.20 GHz with Arm Mali-400MP2 GPU, 1080p60 H.264, MPEG-4, MPEG-1/2 video decoder, H.264 1080p45 video encoder System Memory – 2GB DDR3 SDRAM Storage – 8GB eMMC flash, microSD card slot, M.2 Key-B 2242 socket for SATA SSD Video & audio output – HDMI 1.4 port up to […]

gr-lora_sdr – A GNU Radio SDR implementation of a LoRa transceiver

The physical layer of the LoRa (LoRa PHY) is a proprietary standard owned by Semtech and people have been trying to reverse-engineer the LoRa standard for years with projects such as GR-LoRa, and over the year various people have taken over the works and new projects have come with the latest one being the gr-lora_sdr GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver. The project has been conducted in collaboration with the Telecommunication Circuits Laboratory of the EPFL (École Polytechnique Fédérale de Lausanne) in Switzerland, and gr-lora_sdr is available as a module for GNU Radio 3.10 with both Tx and Rx implemented so it can be used with hardware compatible with GNU Radio that works in the ISM bands for LoRa (e.g. 433 MHz, 868 MHz, 915 MHz). Highlights of the gr-lora_sdr project: Sends and receives LoRa packets between USRP-USRP and USRP-commercial LoRa transceiver (tested with Adafruit Feather […]

SenseCAP T1000 – A credit card-sized LoRaWAN GPS tracker based on Semtech LR1110 (Crowdfunding)

SenseCAP T1000 is an ultra-thin credit-card-sized GPS tracker with Semtech LR1110 wireless chip with LoRaWAN, WiFi (scanning), and GNSS connectivity, plus two built-in sensors to monitor temperature, light intensity, and motion. We’ve covered several LTE IoT and LoRaWAN GPS trackers in the past and even tested the RAK811 LoRa GPS Tracker board with our own gateway, but the SenseCAP T1000 is particularly attractive due to its slim design. It works both indoors and outdoors with IP65 waterproof protection, looks quite easy to set up with its button and LED, and also integrates an SOS feature that can be triggered with a long press. SenseCAP T1000 specifications: Wireless Semtech LoRa Edge LR1110 Asset Management Platform LoRa/(G)FSK Half-Duplex RF transceiver working in the 150 – 960MHz; compatible with LoRaWAN 1.0.4 standard GNSS (GPS/ BeiDou) low-power scanning 802.11b/g/n Wi-Fi ultra-low-power passive scanning Unnamed Bluetooth 5.1 LE chip for initial configuration and indoor positioning […]

Getting started with VOIPAC IMX8M Industrial development kit (Yocto Linux SDK)

Last month I went through an unboxing of the VOIPAC iMX8M Industrial Development Kit with some specs and a quick try with the pre-loaded Yocto 3.1 Linux image. The kit is quite versatile with plenty of interfaces and headers, and eventually, it will support Android 12 and Ubuntu 22.04 LTS. but in the meantime, I played a bit with the Yocto Linux SDK for the NXP i.MX 8M board and will report by experience getting started with VOIPAC IMX8M Industrial development kit. WiFi antennas installation But before checking out Yocto Linux, I will install the two WiFi antennas since I did not do it last time around. We can attach the SMA connectors to the two metal plates on the side of the board securing them with the provided nuts and spacers. The other side of the antenna’s cable comes with a tiny u.FL (or is it MHF4) connector and […]
