The prodigious transistor budgets delivered by modern semiconductor processes enable designers to create powerful processor cores and chips. However, this silicon potential will be for naught if it can't easily be harnessed by algorithm developers. Consider the non-trivial die area and

In last month's edition of InsideDSP , Jeff Bier's editorial discussed the advantages of (and potential issues with) designing an embedded system around an application processor originally developed for smartphones, tablets, and other high volume devices. To wit, at the beginning of his

In reading the InsideDSP newsletter every month, one observation that I hope you've made is that a diversity of processing options exist for implementing digital signal processing algorithms. The alternatives include GPUs, FPGAs, conventional CPUs, and standalone DSPs, along with DSP cores
Analog Devices becomes the latest semiconductor manufacturer to standardize on the increasingly pervasive Eclipse open-source IDE (integrated development environment) and extensible plug-in system with the CrossCore Embedded Studio software suite for C++ and assembly language-based software
Cost- and power consumption-sensitive digital signal processing applications tend to leverage fixed point processors, for a common fundamental reason: fixed-point processor cores are substantially less complex than their floating-point counterparts, leading to reductions in transistor count and

Spansion is a name that's probably familiar to many of you, as a supplier of nonvolatile memories. You might be wondering, therefore, what the company's doing gracing the pages of InsideDSP . Well, hold that thought! Spansion was originally founded in 1993 as a joint venture of AMD and

Over the past 25 years, programmable logic devices have grown in capacity and capability through lithography advancements and the integration of specialized functional blocks. First were dedicated memory arrays derived from the same SRAM used to build logic cells. Next came dedicated-function
"There's been at least one DSP core in every chip that Qualcomm's ever made." Qualcomm senior director of product management Rick Maule used this statement as his lead-in to an explanation of the latest-generation QDSP6 architecture, specifically where it fits in the company
A decade ago, ARM processors were mainly found in cell phones, disk drives, and few other specialized applications. These days, they seem to be everywhere, from microcontrollers to tablet PCs. During this same time period, digital signal processing (DSP) tasks such as multimedia and communications

When people talk about processor benchmarks, the conversation usually ends up being all about speed. Other metrics, such as energy efficiency, are often given less attention or are completely overlooked. The unspoken assumption driving these conversations is that a faster processor is better.
