Intel Curie Board Designed for Wearables is Powered by Quark SE SoC

Intel announced the Edison board at CES 2014, a board targetting wearables and IoT applications about the size of an SD card. At CES 2015, the company has gone smaller, by unveiling the button-sized Intel Curie module powered by a new Intel Quark SE SoC with a motion sensor, Bluetooth Low Energy connectivity and battery charging capabilities. Intel Curie specifications: Low-power, 32-bit Intel Quark SE SoC 384kB Flash memory, 80kB SRAM Low-power integrated DSP sensor hub with a proprietary pattern matching accelerator Bluetooth Low Energy 6-axis combo sensor with accelerometer and gyroscope Battery charging circuitry (PMIC) The module runs an unnamed open source RTOS, and the company will provide IQ software kits for references applications for wearables, such as counting steps, apps for mobile device, and so on. Intel Curie is expected to be found in smart products such as rings, bags, bracelets, pendants, fitness trackers and buttons. There’s basically no […]

Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity

Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB, Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences […]

ARM Introduces Cortex-M7 MCU Core for IoT, Wearables, Industrial and Automotive Applications

ARM has just announced Cortex-M7 processor based on ARMv7-M architecture, with double the compute and digital signal processing (DSP) capability of ARM Cortex M4. The latest ARM MCU core targets IoT and wearables applications for the automotive, industrial, and consumer markets including motor control, industrial / home / factory automation, advanced audio, image processing, connected vehicle applications, and so on. Cortex-M7 comes with enhanced DSP instructions, a better FPU (FPv5 with single and double precision support), and tight coupled memory compared to Cortex-M4, according to an Anandtech article. ARM Cortex-M7 also achieves 5 CoreMark/MHz against 3.41 CoreMark/MHz for Cortex M4, and up to 3.23 DMIPS/MHz against up to 1.95 DMIPS/MHz. ARM Cortex-M7 features listed in the press release: Six stage, superscalar pipeline delivering 2000 Coremarks at 400MHz in a 40LP process. AXI interconnect (supports 64-bit transfer) and fully integrated optional caches for instruction and data allowing efficient access to large […]

$50 Intel Edison Board for Wearables Features an SoC with a Dual Core Atom Processor, and a Quark MCU

Intel announced the Edison board for wearables applications last January at CES 2014. When it first came out, it looked like an SD card, but the board look has now drastically changed. Nevertheless, the important point is that Intel Edison is now available, together with various development kits, and runs Linux (Yocto built), as well as an RTOS. With the official release, we’ve also got the full specifications: SoC – Dual-core, dual-threaded Intel Atom (Silvermont) processor (22nm) processor @ 500 MHz and a 32-bit Intel Quark micro-controller @ 100 MHz.
