Jeff Bier’s Impulse Response—Invasion of the Body Snatchers

May 22, 2013 |

In my December column , I observed that smartphones and tablets are starting to be used in places where purpose-built embedded systems once reigned, such as point-of sale terminals. At home, for example, I have a small Android tablet that I use as an Internet audio player. And my local sandwich

Vision science studies suggest that the eye is able to discern more than 11 bits of dynamic range for each of the three primary colors – red, green and blue – that typically comprise a given scene. The optical nerve connecting each eye to the brain, on the other hand, is only able to

The cellular base station and its associated infrastructure topology have remained largely unchanged throughout the industry's history to date, although upgrades have periodically occurred to address the needs of evolving voice and data standards. Within each base station are beefy

BDTI is well known for its software-related capabilities: performance- and power consumption-related benchmarking , for example, along with algorithm evaluation , and development and optimization work . But the company is no stranger to hardware, either. Take, for example, its recent testing of

"If it has speech recognition, why do we have to use our fingers?" According to Bernie Brafman, Vice President of Business Development at Sensory, that simple question has been at the forefront of many of the company's customers' minds throughout Sensory's 19-year existence.

Soon after BDTI got its start in the early 1990s, we became known for our benchmarks. We benchmarked whatever types of processors people were using for embedded digital signal processing: first DSPs, then CPUs, and eventually MCUs, FPGAs, and GPUs, too. One of the interesting things about

Algorithms are the essence of digital signal processing; they are the mathematical "recipes" that transform signals in useful ways. Companies developing new algorithms, or considering purchasing or licensing algorithms, often need to assess whether an algorithm will fit within their

If you’re a regular reader of this column, you know that I’m enthusiastic about the potential of “embedded vision” – the widespread use of computer vision in embedded systems, mobile devices, PCs, and the cloud. Processors and sensors with sufficient performance

Back in September 2011 , an InsideDSP article described a just-published analysis conducted by BDTI and sponsored by Altera, evaluating the viability of implementing complex hardware-accelerated single-precision floating-point functions on FPGA fabric. As I wrote then: To date, FPGAs have

In a recent interview in EE Times , BDTI co-founder and president Jeff Bier commented: Multi-core CPUs are very powerful and programmable, but not very energy-efficient. So if you have a battery-powered device that is going to be doing a lot of vision processing, you may be motivated
