ARM Cortex-M7 in STM32 F7 STMicroelectronics, IS2T brings MicroEJ Java apps store for embedded market

Posted by Charbax – February 27, 2015

STMicroelectronics launches STM32 F7 series of very high performance Microcontroller Units based on the ARM Cortex-M7 core. The STM32 F7 devices are the world’s first ARM Cortex-M7 based 32-bit microcontrollers, improving on the benchmark performance. Taking advantage of ST’s ART Accelerator as well as an L1 cache, the STM32 F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external Memory: 1000 CoreMark/428 DMIPS at 200 MHz fCPU.

Demonstrated running on the STM32 F7, IS2T MicroEJ SDK enables embedded Java development for any MCU and MPU, from the smallest ARM Cortex-M0+ to the newest Cortex-M7 and beyond. The embedded Java platform includes IS2T Java Virtual Machine (footprint: 28KB of RAM, 1.5KB of RAM) and IS2T libraries for IoT, GUI and communication applications. Boot time to first line of Java main is 2ms on a Cortex-M4@120MHz.

IoT solutions includes TPC/IP, Wifi, MQTT, Websockets, HTTP, JSON, XML, COAP... protocols. GUI solutions includes a full set of widgets, drawing, motions, anti-aliased... libraries - typical animations at 60FPS with less than 10% CPU load. Full Java applications run on MCU starting from 256KB of flash.

The MicroEJ demo running on STM32F7 device shows the Waddapps store connection, an online store of embedded applications that can be downloaded to the STM32F7 through any link (e.g. ethernet, Wifi, Bluetooth). Apps are downloaded, installed, started, stopped, uninstalled without reset - same as smartphone users would typically do with an Apps Store.

STMicroelectronics Set-top-box ARM Processors: STiH312 Cannes and STiH412 Monaco

Posted by Charbax – March 30, 2014

ST’s latest ARM Powered System-on-Chips supporting Android, Google TV (now Android TV), rdk, ST presents their STiH312 client-box and STiH412 server-box product families, codenamed ‘Cannes’ and ‘Monaco,’ respectively, they integrate Faroudja technology to decode and display video up to Ultra HD 4K (2160p) and the next-generation H.265 / HEVC video compression. Even supporting video transcoding (for local and remote streaming from the Set-top-box to Tablets, Smartphones, etc) STMicroelectronics presents their Dual core ARM Cortex-A9 (on 28nm process) with quad-core Mali-400 GPU does Quad-HD Ultra HD 4K HEVC video decoding, combined with Faroudja video processing technology (decoding on Cannes, decoding and transcoding on Monaco), advanced security supporting concurrent conditional access and DRM, wide connectivity, including USB 3.0, PCI-e, SATA and Gigabit Ethernet, Dedicated interfaces to a range of companion front-end solutions, including MoCA 2.0, DOCSIS 3.0, satellite and 802.11ac WiFi and more.

Linaro Security Working Group discussing open source TEE

Posted by Charbax – March 19, 2014

Linaro Security Working Group (SWG), Jens Wiklander, Joakim Bech, Pascal Brand and Cedric Chaumont are talking about what is happening within Linaro's working group that handles security. The group is currently focusing on creating an open source Trusted Execution Environment (TEE) solution running on TrustZone® for ARMv7 and ARMv8 architecture. They also mention that they are going to work on secure boot (UEFI) and DRM schemes (EME) later on. According to SWG there has been and is a lot of interest shown from various companies, markets and countries. People have a hard time trusting a black box that is supposed to protect their most valuable assets. Therefore it is more than welcome to create an open source TEE solution right now, says SWG.

Unbound Robotics UBR 1, Robot development platform

Posted by juliusaugustus – December 11, 2013

The Unbound Robotics UBR 1 is a robot that uses a combination of both ARM Cortex and x86 processors. The UBR 1 is designed as a platform for robotics development and uses ROS (robotics operating system) which is open source. The main processor currently in the robot is an x86 but it uses 12 ST Microelectronics ARM Cortex-M4 based microcontrollers to control each part of the robot.

ARM Embedded in Motor Control demo

Posted by Charbax – March 4, 2011

ARM is showing Motor Control comparing two rotating water vessels, one controlled in a conventional manner, the other is controlled in a more advanced algorithm called Field Oriented Control on a STM32 Cortex-M3 processor. This more advanced algorithm allows more efficient operation of the motor, better control of the torque and allows for quieter operation. The idea is to use less power to control motors. This is just the start of their investigation into Field Oriented Control using the Cortex-M3 processor.
