Beyond The DAC Keynote
By Brian Bailey - 12 Jun, 2014 - Comments: 1

The Design Automation Conference is split into a number of tracks, such as IP, automotive, embedded software and security, and these overlay the main EDA track. One of these themes overlays the first day of DAC, and this year that honor goes to IP. That means that the first keynote of the conference comes from the IP industry, and this is rather fitting given the importance IP is having for ... » read more

Building An Efficient, Tightly-Coupled Embedded System Using An Extensible Processor
By Synopsys - 11 Jun, 2014 - Comments: 0

The increasing demand for better filtering and processing capabilities of the processor within embedded systems results in a trend to shift from 8-bit microcontroller tightly coupled embedded systems towards 32-bit processor bus-based embedded systems. As a consequence, the power, performance and area (PPA) ratio of these systems also shifts in favor of performance at the cost of power and area... » read more

big.LITTLE Technology: The Future of Mobile
By Various Writers - 07 May, 2014 - Comments: 0

With the evolution from the first mobile phones through smartphones to today’s superphones and tablets, the demand for compute performance in mobile devices has grown at an incredible rate. Today’s devices need to service smarter and more complex interactions, such as voice and gesture control, combined with seamless and reliable content delivery. Gaming and user interfaces have also grown ... » read more

Semiconductor Engineering sat down to discuss software-driven verification with Ken Knowlson, principal engineer at Intel; Mark Olen, product manager for the Design Verification Technology Division of Mentor Graphics; Steve Chappell, senior manager for CAE technology and verification at Synopsys; Frank Schirrmeister, group director for product marketing of the System Development Suite at Cadenc... » read more

Are Processors Running Out Of Steam?
By Ed Sperling - 24 Feb, 2014 - Comments: 1

Check out any smart phone these days and you’ll find some reference to the number of cores in the device. It’s not the number of cores that makes a difference, though—or even the clock speed at which they run. Performance depends on the underlying design for how they’re utilized, how often that happens, how much memory they share, how much interaction there is between the cores, and the... » read more

On-Chip MCUs Excel At Power Management
By Ann Mutschler - 10 Oct, 2013 - Comments: 0

By Ann Steffora Mutschler When it comes to supplying power to an SoC, there is an increasing trend to make it more intelligent—how to control it more accurately, how it is monitored and how it communicates with different aspects of the chip. Traditional power supply models with analog supplies have less of this control, so a number of engineering teams are considering the use of on-chip m... » read more

Moore’s Legacy

Low-Power High-Performance Engineering talks with MIPS' Mark Throndson, product marketing director, and Ranganathan "Suds" Sudhakar, chief architect, about Moore's Law, multicore chips, software, coherency and the insatiable global demand for speed. [youtube vid=VfvfYSkPpcs] » read more

Four Factors Driving Processor Choices
By Ed Sperling - 12 Jul, 2012 - Comments: 0

By Ed Sperling Choosing processors for an SoC, a system-in-package, or even a complete system is becoming much more difficult, and the challenge is growing as demands on performance, power, area and time to market continue to increase. There are many reasons why this is becoming more difficult—and some designs will require more tradeoffs than others, depending upon IP re-use or a particul... » read more

Picking The Right Processor
By Frank Schirrmeister - 24 Apr, 2012 - Comments: 1

By Frank Schirrmeister In an embedded system, the sole connection point between the software and the hardware is the processor. Somewhere right now the effort to develop software for a complex System-on-Chip (SoC) is surpassing the effort of developing the chip itself. As I pointed out in my recent description of the Design West conference in San Jose, complex ecosystems of related content, to... » read more

Processor Subject To Change
By Ed Sperling - 09 Feb, 2012 - Comments: 0

By Ann Steffora Mutschler With power complexity driving sophisticated management techniques, SoC design engineering teams are turning to a new class of customizable processor architectures from ARM, CEVA, NVIDIA, Qualcomm and Tensilica and others to take advantage of the best in power saving techniques. While these new architectures are novel approaches, the concepts are not especially new,... » read more
