InsideDSP — In-depth analysis and opinion

Altera Expands Floating-Point Hardware Support Across Its Product Lines

Included in an article on FPGA benchmarking in the September 2011 edition of InsideDSP, BDTI wrote: In design situations where optimum performance and/or power consumption is required, implementing digital signal processing functions in dedicated hardware versus software becomes an attractive proposition. A FPGA is a particularly compelling silicon platform for realizing this aspiration, because it conceptually combines the inherent hardware attributes of an ASIC with the flexibility and time- Read more...

Synopsys' EM5D and EM7D Processor Cores: The ARC Architecture Gains DSP Capabilities

Although the ARC brand has kept a relatively low profile since being acquired by Synopsys in 2009, Synopsys reports that the ARC family of licensable cores are on track to ship more than 1.5 billion units this year. Until recently, ARC's offerings were "vanilla" Harvard architecture CPUs with no DSP-optimized features. That's all changed with the latest EM5D and EM7D (the "D" standing for "DSP"), the first two members of the EM DSP family, which were introduced in late May and are generally Read more...

Lithography, Architecture Evolutions Boost Analog Devices' Mid-Range Blackfin Devices

The April 2012 edition of InsideDSP covered Analog Devices' BF60x family, which as the then-published product roadmap indicated, was the successor to the high end of the BF5xx product range (Figure 1). Figure 1. Analog Devices' new BF70x products fill the "single core Blackfin" next-generation slot on the company's published roadmap two years ago. All four BF60x family members run at clock speeds of up to 500 MHz and integrate a dual Blackfin DSP cores; the BF608 and BF609 additionally embed a Read more...

Jeff Bier’s Impulse Response—Creating Machines That See: Show or Tell?

In 2011, I spoke with Professor Jitendra Malik, a distinguished computer vision researcher and teacher at U.C. Berkeley. Professor Malik, tongue-in-cheek, remarked that he is frequently frustrated when trying to explain his work to non-technical people. In their minds, his research often sounds like an awful lot of effort just to enable a computer to approach the object-recognition capabilities of a toddler. Indeed, this is one of the paradoxes of computer vision. In some cases, vision systems Read more...

Case Study: Diverse Assistance Leads To Vision Processing Optimization Success

As computer vision is deployed into a variety of new applications, driven by the emergence of powerful, low-cost, and energy-efficient processors, companies need to find ways to squeeze demanding vision processing algorithms into size-, weight-, power, and cost-constrained systems. Fortunately, BDTI's foundation as a benchmarking services company has, as has been mentioned before, provided its engineers with extensive skills in optimizing software to best exploit processor capabilities. And it' Read more...

NVIDIA's Jetson TK1 Evaluation Board Gets Embedded Vision

At NVIDIA's GTC (the yearly GPU Technology Conference) in March, the company trumpeted its intentions to broadly supply the embedded market with Tegra SoCs and associated hardware and software development tools. As a specific example of this overarching strategy, NVIDIA unveiled a small form factor development kit called "Jetson TKI" (Figure 1), based on the ARM Cortex-A15-based "Logan" Tegra K1 application processor introduced in January at the Consumer Electronics Show (see sidebar "A Series Read more...

Synopsys Acquires Custom-Processor Design Tool Supplier Target Compiler Technologies

Corporate acquisitions occur for many reasons. Sometimes the market is too small to support multiple participants. Sometimes the acquiring company wants to eliminate a competitor, with aspirations of obtaining the acquired company's customers in the process. Sometimes the acquired company's products are deemed superior in some way, or maybe the acquiring company just wants to get access to a "crack" team of employees. And sometimes multiple of these motivations are behind the transaction. The Read more...

Jeff Bier’s Impulse Response—How Can We Empower Machines to Understand? (Find Out on May 29th in Santa Clara!)

If you're a regular reader of this column, you know that I'm enthusiastic about the potential of "embedded vision" – the widespread, practical use of computer vision in embedded systems, mobile devices, PCs, and the cloud. Processors and sensors with sufficient performance for sophisticated computer vision are now available at price, size, and power consumption levels appropriate for many markets, including cost-sensitive consumer products and energy-sipping portable devices. This is ushering Read more...

Case Study: Chip Vendors, Walk a Mile in Your Customers’ Shoes

Let’s face it: Applications are getting more complicated.  Chips are getting more complicated.  And engineering teams are generally getting smaller, not larger.  As a result, it’s incumbent on chip vendors to provide robust, easy-to-use development kits.  Design engineers rely on these kits to quickly evaluate chips and prototype key portions of their systems. Clearly chip manufacturers recognize that development kits are important, and there are hundreds available.  But the quality of these Read more...

AMD's Kaveri: Will GPGPU Finally Become a Mainstream Reality?

Back in October 2011, InsideDSP covered both recently introduced and pending CPU-plus-GPU products from AMD, along with the cores that they were based on. At the time, AMD referred to CPU-plus-GPU integration as "Fusion"; the company has subsequently renamed such products as APUs (Accelerated Processing Units). And back then, AMD was actively selling two APU lines; "Ontario" (along with the higher-power "Zacate" variant), based on the mainstream "Bobcat" CPU core, and the higher-end "Llano", Read more...
