Atmel SAM S70 and SAM E70 Cortex M7 MCUs, SAM V71 Xplained Board Are Now Shipping

ARM Introduced Cortex M7 IP in September, and ST Micro simultaneously announced its STM32F7 Cortex M7 MCU clocked up to 200 MHz, and boards are now available, including some running Linux. But two other companies have licenses Cortex M7, Freescale with its Kinetis KV5x micro-controllers which are yet to be mass-produced, and Atmel which has recently announced their SAM S70 and E70 micro-controllers are now in mass production. SAM E70 and S70 have similar features, but E70 offers some extra interface like CAN and Fast Ethernet: ARM Cortex-M7 core running at up to 300MHz (1500 CoreMark) Up to 2MB Flash and 384kByte SRAM Floating point unit (FPU) for high-precision computing and accelerated data processing High-performance internal memory architecture with user configurable Tightly Couples Memories and System memory, and 16kB I and D-cache High Speed USB Host and Device with on-chip high-speed PHY CMOS image sensor interface AES hardware encryption engines, […]

Xilinx Introduces Zynq UltraScale+ MPSoC with Cortex A53 & R5 Cores, Ultrascale FPGA

Xilinx Zynq-7000 dual core Cortex A9 + FPGA SoC family was announced in 2012, and provides a wide range of SoC with features and price range, and led to low cost ARM + FPGA such as ZedBoard, and more recently Parallela and MYiR Z-Turn boards. The company unveiled its successor with Zynq UltraScale+ MPSoC providing five times more performance per watt, with four ARM Cortex A53 cores, two ARM Cortex R5 real-time MCU cores, a Mali-400MP GPU, an UltraScale FPGA fabric manufactured with 16nm FinFET+ process. There are two main sub-families in Zynq Ultrascale+ MPSoC for “smarter control & vision”, and “smarter network”. Both share the same processing systems (CPU, GPU, MCU, Peripherals, Security), but the networking family has beefier FPGAs, and lacks the H.264/H.265 video processing unit found in the control & vision version: Processing Systems Processor – Quad ARM Cortex A53 MPCore up to 1.3GHz Real-time Processor – […]

FOSDEM 2015 Schedule – January 31 – February 1 2015

FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]

Meet Freescale Kinetis KL03, the Smallest Ever ARM MCU

Last year at Embedded World 2013, Freescale announced Kinetis KL02, an ARM Cortex M0+ MCU measuring just 1.9 x 2.0mm. Customer must have complained that it’s not small enough, as the company has just unveiled Kinetis KL03 MCU, 15% smaller or 1.6 x 2.0 mm, at Embedded World 2014. Just like its predecessor KL03 targets space-constraint IoT applications such as ingestible healthcare sensing, portable consumer devices, remote sensing nodes, and wearable devices. Kinetis KL03 MCU features include: 48 MHz ARM Cortex-M0+ core, 1.71-3.6V operation Bit manipulation engine for faster, more code-efficient handling of peripheral registers 8 to 32 KB flash memory, 2 KB RAM, 8K ROM with on-chip boot loader High-speed 12-bit ADC Internal voltage reference for high ADC accuracy High-speed analog comparator Up to 22 GPIOs with pin interrupt support Low-power UART, SPI, I2C (high speed) Low power wake up Secure real time clock Timers for a broad range of […]

2013 Embedded Market Study – Software Development & Processors

UBM releases a study of the embedded market every year, by surveying over 1,000 embedded professional every year. They’ve just published their 2013 Embedded Market Study (85 pages report), after surveying over 2,000 engineers and managers, so let’s see whether anything has evolved in the software development and processor space compared to 2012. Again this year, most respondents are based in the US (62%), followed by Europe (20%), and Asia (12%). C/C++ languages still rule the embedded world with 81% market share, although a little less than last year (85%), assembler is a distant third (5%). Interestingly, the average size of development teams seems to have shrunk from 15.9 in 2012 to 14.6 in 2013, the average project being composed of 4 software engineers, 2.9 hardware engineers, 2.7 firmware engineers, 2 QA/Test engineers, 1.5 system integrators, and 1.5 with other functions. About a third of project last less than 6 […]

2012 Embedded Market Study – Software Development & Processors

I’ve just come across an Embedded System Study by UBM published in April 2012. The company surveyed over 1,700 professionals working on embedded systems who are mainly based in the US (56%), but also in Europe (21%) and Asia (12%). The report is 87 long, but I found some of the slides are particularly interesting in regards to programming languages, operating systems and software life cycle, as well as processor/micro-controller choices. Unsurprisingly C (65%), C++ (20%) and assembler (5%) are still the main languages used for embedded software development. In this report, we also learn that the average team is composed of 14.5 members including 5.6 software engineers, 5.6 hardware engineers and 3.3 firmware engineers. 2012 was the first year they included QA Engineers and system integrators both with 2.6 members on average working on projects lasting from less than 6 months to over 25 months. UBM survey also provides a […]

Brew Your Own Beer with Freescale Kinetis Cortex M4 MCU

This brewing system is part of top three designs for Freescale Make It Challenge: Kinetis MCUs. The two other designs are an Automobile Collision Detector and a “Swiss Army Knife” for the Blind . This design utilizes Freescale’s Kinetis K60 Tower System with MK64M512 Cortex M4 MCU and FreeRTOS operating system. This could become a beer brewing appliance with the target market being home brewers and small brewpubs and restaurants. Matthew Pratt (the one who design this system) says current hone brewing systems sell for about 10,000 USD. The sweet wort production process can be labor-intensive, requiring precise control of temperatures and transition times (It takes 4 to 5 hours for 5 gallons of beer). The Kinetis Beer Brewing System automates the process from the initial filling of water to the beer being ready to be cooled and yeast added. The user only needs to add the ingredients, malt and […]
