DSP-Based Testing
By Various Writers - 16 Apr, 2014 - Comments: 0

ADC and DAC are the most typical mixed signal devices. In mixed signal testing, analog stimulus signal for an ADC is generated by an arbitrary waveform generator (AWG) which employs a D/A converter inside, and an analog signal out of a DAC is measured by a digitizer or a sampler which employs an A/D converter inside. The stimulus signals for these devices are created using mathematical method, ... » read more

Are Processors Running Out Of Steam?
By Ed Sperling - 14 Feb, 2014 - Comments: 4

In 2004, Intel introduced a new line of Pentium chips that ran at 3.6GHz. Fast forward to today, and the company’s i7 processors run at 3.5GHz with a Turbo Boost to 3.9GHz. There have been many improvements in the meantime. There is more cache and dramatically faster access to data stored in that cache. And there are more cores with improved coherency between them. But the big problem is p... » read more

Designing An Efficient Multi-Core LTE-A Modem
By Various Writers - 12 Feb, 2014 - Comments: 0

LTE-Advanced represents the next generation mobile broadband, and in turn throws the challenge to the designers to create highly power efficient mobile devices capable of delivering these services. ARM, the leading supplier of embedded processors, physical IP and inter-connect fabric, along with CEVA propose a joint analysis looking at the design considerations that are required to realize the ... » read more

Performance Still Trumps Power
By Brian Bailey - 16 Jan, 2014 - Comments: 2

When it comes to technology, the past was always simpler than the present and the future looks daunting. In part, this is because finding a solution to a problem allows us to discover the next problem. Over time, the previous problem becomes more understood and solutions improve to the point where it is no longer considered a problem. It was a fairly easy choice about how to implement functiona... » read more

The Week In Review: System-Level Design
By Ed Sperling - 10 Jan, 2014 - Comments: 0

Cadence won a deal with Fraunhofer, which licensed its MPEG codecs for Tensilica HiFi DSP. (Cadence acquired Tensilica last year.) The AAC codecs combine speech and general-purpose audio into a unified system, which simplifies design because it works at any bit rate. Sonics won a deal with MediaTek, which licensed its NoC technology for an upcoming line of SoCs. MediaTek, based in Taiwan, is... » read more

The Week In Review: System-Level Design

Si2’s OpenPDK rolled out its Open Process Specification 1.1, including elements necessary to automatically create a process design kit using any EDA vendor’s design flow. The standard uses formal grammar based on the XML Schema Definition. ARM won a deal with Rockchip, which is extending its license to a number of ARM processors as well as its GPU and interconnect technology. This marks ... » read more

New Silos Form In IC Industry
By Ed Sperling - 25 Jul, 2013 - Comments: 0

By Ed Sperling For the past couple of decades corporations around the globe have been focused on down silos. In fact, it has become a mantra. It’s considered essential for making established corporations even more successful, and it’s almost always at the center of turnaround plans for troubled companies. Moreover, across a full spectrum of companies, it’s regularly cited by management c... » 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
