NXP i.MX 8M Mini Pico-ITX SBC Comes with Audio DSP, Optional PoE and Google Coral M.2 Module

We’ve covered several NXP i.MX 8M Mini SBC‘s since the announcement of the processor in 2018 as the first i.MX SoC manufactured with a 14nm process allowing for a higher CPU clock of 2.0 GHz compared to the 1.5 GHz frequency used with the original i.MX 8M processor. i.MX 8M Mini also removes some features (4K video playback, some video interfaces, …) in order to lower the cost of the processor. Companies are still releasing new i.MX 8M SBCs regularly, but we don’t always cover them all since many often do not offer much compared to the competition. But Estone Technology EMB-2237-AI Pico-ITX SBC has some unusual features and options including a Cirrus Logic audio DSP, as well as support for a PoE module and Google Coral M.2 AI accelerator module. EMB-2237-AI SBC is comprised of a system-on-module and baseboard with the following specifications: Estone SOM-2237 module SoC – […]

Register to the Embedded Online Conference for Free Before February 29th

Events such as the Embedded Linux Conference and Embedded Systems Conference take place in the US and Europe every year. There are plenty of talks and it’s certainly good for networking, but you need to travel to the event and the entrance fee to have access to all session costs several hundred dollars if you book early, and over one thousand dollars if you register close to the date of the event. Most ELC/ELCE videos usually end up on The Linux Foundation YouTube channel, but the Beningo Embedded Group and Embedded Related website decided to organize a similar conference happening online and simply called the “Embedded Online Conference“. The conference offers topics about embedded systems, DSP, machine learning and FPGA and will take place on May 20. There are currently 17 talks, but they are still calling for talks so more sessions may be added before the actual event. You’ll […]

Arm Helium Delivers up to 15x Performance Uplift for Machine Learning on Cortex-M MCUs

Arm has just unveiled Armv8.1-M architecture that adds Arm Helium technology, the M-Profile Vector Extension (MVE) for the Arm Cortex-M cores that will improve the compute performance of Cortex-M based microcontrollers. Helium will deliver up to 15 times more machine learning (ML) performance and up to 5 times uplift to signal processing allowing local decision-making on low-power embedded devices. Helium instructions will enable new applications for Arm Cortex-M microcontrollers in audio devices, sensor hubs, keyword spotting, voice command control, power electronics, communications and still image processing. Helium and Neon (the Advanced SIMD technology for Arm Cortex-A processors) are similarities but Helium has been designed for efficient signal processing performance in small processors. One different illustrated below is that while NEON loads 128-bit instructions (e.g. VLDR, VLMA), Helium will split up 128‑bit wide instruction into four equally sized chunks, called “beats” (labelled A to D) due to difference between Cortex-M and […]

Intel Quark S1000 “Sue Creek” Processor to Support On-Chip Speech Recognition

Intel may have announced plans to discontinue several of their IoT boards, but based on some documents I received, the company has not given up on the Quark family, although they may have given up on the Intel architecture for low power microprocessor, as Intel Quark S1000 – codenamed “Sue Creek” – will feature two Tensilica LX6 cores (yes, just like ESP32), and is designed to handle speech recognition at the edge (e.g. locally), so some of your voice commands should still work when Internet is down. Intel Quark S1000 key features and specifications: Digital Signal Processors Dual Tensilica LX6 cores @ 400 MHz with HiFi3 DSP Single precision scalar floating-point instructions 16KB 4-way I$; 48KB 4-way D$ Up to 2400 DMIPS, 3.2 GMACS (16×16), 800 MFLOPS of Compute Speech Accelerators A GMM (Gaussian Mixture Model) and neural network accelerator Low power keyboard and limited vocabulary recognition Up to 9.6 […]
