How Many Cores? (Part 1)
By Ed Sperling - 10 Mar, 2016 - Comments: 2

The optimal number of processor cores in chip designs is becoming less obvious, in part due to new design and architectural options that make it harder to draw clear comparisons, and in part because just throwing more cores at a problem does not guarantee better performance. This is hardly a new problem, but it does have a sizable list of new permutations and variables—right-sized heteroge... » read more

The Week In Review: Design/IoT
By Ed Sperling - 24 Dec, 2015 - Comments: 0

Acquisitions Synopsys acquired Australia's Goanna Software, a security company focused on static code analysis tools for improving code quality. Synopsys said the acquisition is part of its strategy to improve software sign-off, but the acquisition also expands Synopsys' presence in Australia and the Asia/Pacific region. Terms of the deal were not made public. Synopsys has been steadily build... » read more

Bridging Hardware And Software
By Ann Mutschler - 22 Dec, 2015 - Comments: 0

Since the advent of embedded systems there has been a struggle between hardware engineers trying to understand the mindset of their software counterparts, and vice versa. That struggle is alive and well today—and it's costing everyone money. This divide is rife with passion, territoriality and misunderstanding. It has delayed tapeouts, created errors and inefficiencies that take time and e... » read more

How To Choose A Processor
By Ann Mutschler - 10 Dec, 2015 - Comments: 0

Choosing a processor might seem straightforward at first glance, but like many engineering challenges it's harder than it looks. When is a CPU better than a GPU, MCU, DSP or other type of processor? And for what design—or part of a design? For decades, the CPU has been the default choice. “It is deliberately designed to be pretty efficient at all tasks, is straightforward to program, ... » read more

Can The IoE Ever Be Secure?
By Ed Sperling - 07 Dec, 2015 - Comments: 2

There are many different opinions about how the [getkc id="76" comment="Internet of Things"]/[getkc id="260" comment="Internet of Everything"] ultimately will look, who is best positioned to take advantage of it, and how processing will be split between local devices, the cloud, and everything in between. But there is almost universal agreement on one point: It's not secure enough. "In the p... » read more

Making Cars Smarter
By Ann Mutschler - 05 Nov, 2015 - Comments: 1

The fuel injection control unit has come a long way since 1983 when Ford Motor Co. first included a 16-bit Intel microcontroller-based fuel injection system in its 4-cylinder Escort. Today, some high end vehicles contain more than 100 microprocessors, which is mind boggling in comparison to that Escort that contained just one. To be sure, the automotive industry is a unique animal. Compared ... » read more

Making Cars Better
By Jérôme Toublanc - 11 Sep, 2015 - Comments: 0

The automotive industry, with its double-digit growth, is a very attractive market for equipment manufacturers. This growth is explained not only by the increasing number of cars produced for the Asia market, but also by the shift of basic customer expectations for things such as more hybrid and electrical vehicles, more sophisticated infotainment requirements, and more high-end features. O... » read more

5 Things To Know About The IoT
By Ed Sperling - 06 Aug, 2015 - Comments: 0

The IoT means many things to many people. While the numbers and projections are all very large, the views of what it actually means are vastly different because it can include anything from a sensor in a car or an ingestible medical device to a data center full of servers and the connectivity in between. But there are some interesting shifts under way, both driving the [getkc id="76" comment... » read more

The Next Generation Of Wearables
By Ernest Worthman - 07 May, 2015 - Comments: 0

As the wearable market begins to take root, so has the focus on ultra-low power design—with some unique headaches that are unique to wearables. To begin with, there is much attention being paid to this market because of the almost staggering predictions associated with it. While numbers vary greatly, IDC predicts as many as 126 million units will be shipping annually by 2019. The five-year... » read more

Custom Versus Platform Design
By Ed Sperling - 26 Feb, 2015 - Comments: 0

The increase in [getkc id="81" kc_name="SoC"] complexity is being mirrored by a rise in complexity within the markets that drive demand for those chips. The upshot is that a push toward greater connectivity, lower power and better performance—and all for a minimal cost—has turned the pros and cons for custom design vs. platforms and superchips into a murky decision-making process. For t... » read more
