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

Arm Helium

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 Cortex-A cores as explained in details in an Arm Research …

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 GMACS (16×16) of compute Internal Memory 4MB shared embedded SRAM …

Qualcomm Snapdragon 820 Promises Twice the Performance & Power Efficiency of Snapdragon 810

Qualcomm has provided more details about Snapdragon 820 processor featuring custom-designed 64-bit ARM Kryo cores, an Adreno 530 GPU and an Hexagan 680 DSP, with claims that it should be twice as fast and consume half the power of Snapdragon 810 processor with Cortex A57 and A53 cores. Based on the chart below, it will also be faster than Snapdragon 620 with Cortex A72 and A53 cores. Snapdragon 820 will feature four Kryo cores (succeeding Krait cores) clocked at up to 2.2 GHz and be manufactured using 14nm FinFET process technology. Adreno 530 GPU is expected to deliver over 40% performance improvement over Adreno 430 GPU while also keeping power consumption 40% lower, a new Spectra camera dual ISP will support 14-bit sensors, and Hexagon 680 DSP adds a separate low power DSP for always-on sensor processing, and support for HVX (Hexagon Vector eXtensions) to be used for advanced imaging and computer vision. This will for example greatly accelerate low …
