Heterogeneous SoC design gets its own foundation backed by heavy hitters. Good things sure to follow
I am an unabashed advocate of heterogeneous SoC design. Have been for decades. It’s a system-level design approach that lacks the elegance and academic symmetry of homogeneous processing in exchange for a more efficient, bare-metal, hard-core approach to system design … Continue reading
Freescale demonstrates first-pass Kinetis L silicon at Design West (The conference formerly known as the Embedded Systems Conference)
Two weeks ago, ARM introduced its new low-end Cortex-M0+ 32-bit processor core. At the same time, Freescale announced that it was planning on introducing a new line of Kinetis “L” low-power microcontrollers based on the ARM Cortex-M0+ processor. (See “How … Continue reading
As part of this week’s DVCon event being held in Silicon Valley, the EDAC Emerging Companies Committee sponsored a really intense and well-attended evening panel on hardware/software codesign. The effervescent Paul McLellan moderated the panel. (If you’ve not read his book, … Continue reading
Infineon launches microcontroller series based on ARM Cortex-M4 core, targets industrial drives, power and energy conversion, and automation
Last month, Infineon introduced the XMC4000 series of microcontrollers based on the ARM Cortex-M4 processor core augmented with a floating-point unit. (Note: Don’t confuse the Infineon XMC4000 series with the NXP LPC4000 series of microcontrollers based on the ARM Cortex-M4 … Continue reading
Friday Video: Multicore, ARM-powered CubeStormer II solved Rubik’s Cube puzzle in world-beating 4.762 seconds
A couple of weeks ago, I posted a video of the ARM-powered CubeStormer II, a robotic mechanism constructed from four Lego Mindstorm NXT kits, that’s purpose-built to unscramble Rubik’s Cubes in the minimum amount of time. The CubeStormer II envelops … Continue reading
Friday Video: Are apps just for Smartphones? Nope. Take a look at this EEVblog video of new firmware for the Agilent InfiniiVision 3000X DSO
Say “apps” and smartphones likely come to mind immediately. No wonder, since that’s how most of us interact with apps on a daily basis. As all sorts of devices get smarter and smarter, the concept of apps-driven design—fundamental to EDA360—makes … Continue reading
Ryan Whitwam over at Extremetech.com has just published an interesting article comparing the system-level power-management approaches taken by the Nvidia Tegra 3 and Qualcomm Snapdragon 4 ARM-based multicore SoCs. Both of those products have been discussed here at the EDA360 … Continue reading
3-processor SoC for digital still cameras incorporates an ARM 1136J-S RISC processor core plus separate image and video processors
One more process node click, from 45nm to 32nm, bumped the clock rate of the Ambarella A7L SoC’s on-chip ARM 1136J-S RISC processor core to 600MHz from 528MHz. But reading the press release, I get the impression that the real … Continue reading
Jim “make me some money” Hogan, perhaps the most visible VC in EDA, has just published an article titled “Jobs’ Law” on the System-Level Design Community Web site where he defines Jobs’ Law (Jobs, Steve Jobs, who shakes whole industries … Continue reading
Want to know how to get a serious calculator collector salivating? Bring back a favorite design from 1982, re-engineer the design so that the old code runs on top of an emulation layer that allows the use of a “modern” … Continue reading
Sure, we all complain about boot times. For our PCs. For our laptops. For our smartphones. For our Blu-ray players. I don’t know who gave engineers a pass on boot times, but Lenovo at least is taking a funny and … Continue reading
Although it’s not presented at a 3D story to the public, the Raspberry Pi Foundation’s $25 alpha board based on a 700MHz ARM 11 processor is very much 3D because there’s an SDRAM stacked on top of the processor. Why? … Continue reading
“Software design costs have eclipsed silicon design efforts and have become the largest portion of the SoC creation effort.” That’s one conclusion of a new Semico report titled “SoC Silicon and Software Design Cost Analysis: Changes in Perspective.” This report … Continue reading
When I told my good friend David Thon that Google’s planned purchase of smartphone maker Motorola Mobility was a pure EDA360 play, he invited me to explain. In simplest terms, EDA360 posits that software now drives hardware in the processor-centric … Continue reading
More EDA360 philosophy lessons from Agilent. What are the realities of today’s engineering economics?
