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

"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

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

Qualcomm recently opened up the QDSP6 (aka "Hexagon") DSP core in its Snapdragon SoCs to programming access by its customers and software developer partners. Multimedia applications, for example, can benefit from leveraging QDSP6 processing resources , boosting overall performance,

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

In my December column , I wrote about how smartphones and tablets are subsuming some categories of consumer electronics, such as MP3 players and networked home audio players. Because smartphones and tablets are network-centric devices, their growing use as media players is contributing to another

Within a technical article published in the August 2012 edition of InsideDSP , I wrote: As FPGAs have evolved, the means by which engineers create FPGA designs have also evolved. In particular, design techniques employing increasingly higher levels of abstraction have been required to
