Jeff Bier’s Impulse Response—Power is the New Performance

April 10, 2013 |

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

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

Mobile phones are rapidly and dramatically expanding beyond their historical usage as voice-only communications devices, adding a variety of wireless data-fed text, email, web browsing and other functions, supplementing (and in many cases supplanting) the facilities of dedicated still and video
