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

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.

Last month's edition of InsideDSP discussed MIPS' recent three-core Aptiv product family announcement and provided detailed information on the high-end proAptiv offering. This follow-up article will cover the mid-range interAptiv and entry-level microAptiv cores. As with proAptiv,

Processor core provider MIPS Technologies has seemingly fallen on hard times in recent years. Consider, for example, a report published by the Linley Group just last week that indicated chief competitor ARM supplied CPU cores used in 78% of the estimated 10 billion CPU cores in SoCs shipped last

Note: the earlier-published (and reversed) 'tick' and 'tock' descriptions have been corrected. Jerry Sanders, AMD's brash former CEO, once opined, "Real men have fabs. These fabless guys are nobodies, just boys." In recent times, however, Sanders'

"If it's not broken, don't fix it." That well-known maxim seemed for many years to encapsulate CEVA's approach to audio DSP cores, given that the company's third-generation offering in this particular application space (and first-generation 32-bit core), the
