STMicro Intelligent Sensor Processing Unit (ISPU) combines MEMS sensor with DSP for AI “in the edge”

ISPU flexibility, low-power, data transfer

STMicroelectronics’ Intelligent Sensor Processing Unit (ISPU) is a single chip that combines a MEMS sensor together with a Digital Signal Processor (DSP) designed to run AI algorithms to let the chip make electronic decisions “in the edge” without help from the cloud or a local gateway. The ISPU is said to offer a smaller size compared to system-in-package devices, cut power consumption by up to 80%, and according to STMicro, launch the new “Onlife era” following the “Offline era” of the 2000’s where sensors were controlled by MCUs without network connectivity and the “Online era” in the 2010’s when sensors became connected to the cloud or a local gateway. ISPU key features: Enhanced 32-bit RISC Harvard architecture Extensible at the chip design phase with dedicated instructions or HW components Frequency / ODR (Output Data Rate) max – 5 MHz / 3.33 kHz – 10 MHz / 6.66kHz Four-stage pipeline 16-bit […]

Amazon Alexa certified ESP AFE leverages ESP32-S3 AI & DSP instructions

While most Amazon Alexa certified products are hardware designs, Amazon website also includes a Software Audio Front End (AFE) Dev Kits section that lists software algorithms that optimize audio detection in noisy environments, and the latest addition is Espressif’s Audio Front-End algorithms, or ESP AFE for shorts, that have recently been qualified for Amazon Alexa devices. It’s not the first Alexa certified solution from Espressif Systems, as both companies have worked together in the past with audio products like the ESP32-PICO-V3-ZERO Alexa Connect Kit Module or ESP32-Vaquita-DSPG board The algorithms were created by Espressif’s AI Lab team who used the AI and DSP instructions inside ESP32-S3 processor to optimize the code. The algorithms only utilized 12 to 20% of the CPU, as well as 220 KB of internal and 240 KB of external memory, leaving extra resources for other applications running in the wireless SoC. The ESP AFE is said […]

Amlogic S905X3 vs S905X4 – Features Comparisons

AV1 capable Amlogic S905X4 processor has been expected for more than a year, and only now are we starting to see announcements of S905X4 TV boxes and development kits. So it may be a good time to compare the features of the new Amlogic S905X4 processor again its predecessor, namely S905X3, and see if there are other notable differences apart from support for AV1 open video codec. We’ll use data from S905X3 specifications, S905X2 vs S905X3 comparison, and a post on SDMC LinkedIn page. Amlogic S905X4 will be slightly faster due to the higher (default) maximum CPU frequency of 2.0 GHz, but most people will not notice the difference. S905X4 is supposed to support Vulkan 1.1, while S905X3 does not, but I believe this is just due to more up-to-date Android SDK, and not differences in the silicon itself. S905X4 supports Nagra DRM, a more recent version of HDCP, and […]
