EEMBC IoT-Connect is a Family of Benchmarks Designed To Test the Power Efficiency of IoT Devices

EEMBC, the Embedded Microprocessor Benchmark Consortium, has been providing benchmarks for embedded systems since 1996, including ULPBench helping to rank micro-controllers by their power efficiency. But with the Internet of Things gaining traction, it’s important to test more than just the MCU core’s power efficiency, and having a benchmark taking sensors and connectivity into account would be useful. That’s exactly what EEMC IoT-Connect benchmark family aims for with the three main characteristics: Provides flexibility to accommodate various communication protocols (e.g. Bluetooth, Thread, LoRa, WiFi) Portable to work with any vendor’s microcontroller and radio-module products Compatible with EEMBC ULPBench and EEMBC IoT-Secure benchmarks The first benchmark of the family is IoTMark-BLE connectivity profile that supports Bluetooth (LE) MCUs. The benchmark requires fixed payload size, frequency of transmission, and transmit power, and performs a complete sequence of event ranging from sensor reading, to BLE notifications, and command write and CRC. The IoT-Connect […]

New Espressif ESP32 Single and Dual Core Processors in 5x5mm Package, Optional Embedded Flash Coming Soon

Espressif ESP32 was launched last year as a dual core Tensila processor with WiFi and Bluetooth connectivity, relying on external flash for storage, and packaged into a QFN48 6x6mm package. Espressif recently updated ESP32 datasheet, and the guys at ESP32net noticed three new versions of the processor with a QFN48 5x5mm package, one version including 2 MBytes embedded flash, and another version with a single core. The three new versions of ESP32 all come with the same WiFi 802.11b/g/n ad Bluetooth 4.0 LE connectivity and a QFN 5×5: ESP32-D0WD dual core processor without embedded flash ESP32-D2WD dual core processor with 16 Mbit embedded flash ESP32-S0WD single core processor without embedded flash ESP32-D0WD different with ESP32-D0WDQ6 is only the smaller package, while ESP32-D2WD brings 2MB embedded flash too possibly lowering the price of current solution with external flash, and ESP32-S0WD might be closer to ESP8266 price thanks to its single core, […]
