AMD Announces ARM and x86 pin-to-pin Compatible APUs and SoCs for 2015, ARM K12 Core for 2016 and Beyond

AMD has designed x86 processor since its inception, and recently they’ve announced ARM Cortex A57 “Seatlle” SoCs targeting servers would be available later this year. They’ve now decided to merge their product line-up even further with Project Skybridge that aims to provide pin-to-pin compatible ARM and x86 SoCs and APUs by 2015, manufactured using a 20nm process. That means AMD’s customers should be able to leverage AMD’s “ambidextrous computing” solutions to design one and only board for x86 and ARM processors for server, embedded, semi-custom and ultra-low power applications. Processors of the “Project Skybridge” family will also be the first ARM based AMD processors to include a GPU (Graphics Core Next GPU), contrary to Seatlle SoCs, which are destined to be used for the server market, and do not come with a GPU. ARM processor will be based on low power ARM Cortex A57 cores and x86 processors will make […]

Embedded Linux Conference 2014 Schedule

The Tenth Embedded Linux Conference (ELC 2014) will take place on April 29 – May 1, 2014 at the San Jose Marriott in San Jose, California. The event will feature 90+ sessions on embedded Linux, Android and IoT with over 450 attendees expected to attend. It will also be co-located with Android Builders Summit and the AllSeen Alliance Hackfest. Even if you can’t attend it’s still interesting to see what will be discussed at the event to get a grasp of on-going developments, learn a few things about different optimization techniques, and so on. So I’ve gone through the sessions’ description, and I’ve designed my own virtual schedule with sessions that could be of interest. April 29 9:00 – 9:30 – Keynote: The Paradox of embedded and Open Source by Tim Bird, Sony Mobile Linux has taken the embedded world by storm. Billions (with a ‘B’) of devices have now shipped […]

MCU Energy Efficiency Benchmark – Freescale KL02, Microchip PIC24, TI MSP430, and STMicro STM32L

Freescale has recently uploaded a video comparison the energy efficiency of several micro-controllers: Freescale Kinetis KL02, Texas Instruments MSP430, STMicro STM32L, and Microchip PIC24. Since it’s a Freescale video, we already know the winner, but the test they performed it still interesting, and it shows drastic performance differences between architectures. The used the following exact MCU for testing: Freescale MKL02Z32CAF4R – Cortex M0+ @ 48 MHz STMicro STM32L151RBT6 – Cortex M3 @ 32 MHz Microchip PIC24FJ128GA308 – 16-bit MCU @ 32 MHz Texas Instruments MSP430F5529 – 16-bit MCU @ 25 MHz Freescale did not really select tough competition such as NXP LPC800 Cortex M0+, but instead a Cortex M3 MCU, and older 16-bit MCUs. I don’t know if Microchip has a new generation of ultra low power 16-bit MCUs , but Texas Instruments, for example, launched MSP430 Wolverine MCUs at the end of last year. So this comparison may not be […]

ARM TechCon 2012: Software & System Design Schedule

ARM Technology Conference (TechCon) 2012 will take place on October 30 – November 1, 2011, in Santa Clara, and UBM Electronics has already posted the detailed schedule for the event. The first day (October 30) will be Chip Designs day and the other 2 days will focus on Software & System Design. Even if, like me, you are not be able to go there, it’s still interesting to know what will be discussed at the conference, to have a better idea where ARM is going, and what new technologies and/or development techniques are (or will become) available. There will be around 70 sessions categorized in 15 tracks: Android / Open Source – Development tools, middleware for native application development, and optimized drivers for Android, Linux, FreeRTOS etc … Compute Platforms – Development and implementation of standards and specifications, from board/module design to consumer and server designs Developing / Debugging – […]
