Atmel Introduces SAMA5D4 Embedded MPUs With 720p Video Decoder And TrustZone Support

Atmel has expanded its SAMA5 Cortex A5 embedded processor family with SAMA5D4 series adding an optional video processing unit capable of decoding H264, VP8 and MPEG4 at 720p / 30fps, as well as support for ARM NEON and TrustZone technology. There are also some other changes with regards to connectivity: no Gigabit Ethernet, more UART interfaces, less SPI interfaces, etc… Key features listed of Atmel SAMA5D4 series:: ARM Cortex-A5 core up to 528MHz (840DMIPS) with NEON & TrustZone support, 2x 32KB L1 cache, and 128KB L2 cache. Optional 720p hardware video decoder supporting H264/263, VP8, JPEG, and MPEG4. Graphic LCD TFT controller with overlays for image composition, resistive touchscreen controller. CMOS image sensor interface. Three high-speed USB ports (configurable as three hosts or two hosts and one device port). Dual EMAC 10/100 with IEEE1588 support (Precision Time Protocol). Other I/Os – 8x UART,  8x SPI, 4x TWI, 2 HS SDIO/SD/MMC, 2x I2S Advanced security features to prevent counterfeiting, secure external […]

ARM Announces mbed OS for ARM Cortex-M Micro-controllers and mbed Device Server for the Cloud

ARM has just announced two new software products for mbed development boards at ARM Techcon 2014: mbed OS, an operating system for Cortex-M MCUs, and mbed Device Server to handle IoT data in the cloud. Together with existing mbed hardware, these form what ARM now calls mbed IoT Device Platform. mbed OS is a free operating system for ARM Cortex-M processor with security, communication and device management features necessary to enable IoT devices. It will provide a C++ application framework, and the software stack includes support for Bluetooth Smart, 2G, 3G, LTE and CDMA cellular technologies, Thread, Wi-Fi, 802.15.4 / 6LoWPAN,  TLS/DTLS, CoAP, HTTP, MQTT and Lightweight M2M. No need to look for your mbed board, planning to try it out just yet however, as mbed OS (alpha) will be available to partners in Q4 2014, and there will be alpha and beta releases during the course of 2015, before the official mbed 3.0 OS release at ARM Techcon 2015.

STMicro STM32F4 (Cortex M4) vs STM32F7 (Cortex M7) Graphics Demo

STMicro announced their latest STM32F7 micro-controller family based on ARM Cortex M7 last week. As ARM Techcon 2014 is now taking place, the company has uploaded an infomercial on their YouTube account, where STMicro and ARM representatives are interviewed about the new family, and talk about its performance, power consumption, target applications, business prospects, and so on. But there’s also an a short demo with two development kits one with a STM32F4 cortex M4 micro-controller, and the other with a STM32F7 micro-controllers. Since both MCU families are pin-to-pin compatible, the hardware is identical except for the MCU. Both kits are pre-loaded with a 3D graphics demo (ray tracer), and the board with STM32F7 completes the demo in about half the time of the one with STM32F439, allegedly with about the same power consumption (7 coremarks / mW). The video is about 8 minutes long, and the demo starts at 1:25. STMicro is only working with selected partners for now, and […]

ARM TechCon 2014 Schedule – 64-Bit, IoT, Optimization & Debugging, Security and More

ARM Technology Conference (TechCon) 2014 will take place on October 1 – 3, 2014, in Santa Clara, and as every year, there will be a conference with various sessions for suitable engineers and managers, as well as an exposition where companies showcase their latest ARM based products and solutions. The detailed schedule for the conference has just been made available. Last year,  there were 90 sessions organized into 15 tracks, but this year, despite received 300 applications,  the organizers decided to scale it down a bit, and there will be 75 session in the following 11 tracks: Chip Implementation Debugging Graphics Heterogeneous Compute New Frontiers Power Efficiency Safety and Security Software Development and Optimization Software Optimization for Infrastructure and Cloud System Design Verification There are also some paid workshops that take all day with topics such as “Android (NDK) and ARM overview”, “ARM and the Internet of Things”, or “ARM Accredited Engineer Programs”. As usual, I’ve gone through the schedule […]
