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

The article, " QDSP6 V4: Qualcomm Gives Customers and Developers Programming Access to its DSP Core ," which appeared in the June 2012 edition of InsideDSP , showcased Qualcomm’s decision to open up access to its DSP core via a software development kit. This decision corresponded

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

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

In my October column , I explored the phenomenon of mobile application processors (the brains of smartphones and tablets) competing against more traditional types of embedded processors for use in embedded systems. But after writing that column, something happened that made me realize that mobile

Semiconductor memory is increasing in capacity and cost-effectiveness all the time. Yet, there are plenty of deeply embedded applications for which every spare byte of RAM or flash memory is a precious commodity, especially those leveraging memory integrated onto an SOC of processor, rather than

We tend to think of digital signal processing as being computationally demanding, since it typically involves applying math-intensive algorithms to real-time streaming data. And, compared with many other types of embedded processing tasks, digital signal processing does indeed make heavy demands on
