While nearly all signal processing applications require some degree of software optimization, some applications require a sophisticated, multi-tiered optimization approach in order to meet their performance goals. To obtain the most efficient code, DSP software must be optimized at four

At the Consumer Electronics Show last month I was struck (not for the first time) by the number of consumer electronics products that rely on digital signal processing—at this point, nearly all of them. In fact, so many of today's products incorporate digital signal processing-based
On January 3rd, Freescale announced the first dual-core members of its Onyx family of audio DSPs. The first two chips in the family, the DSP56720 and DSP56721, feature two DSP5636x cores operating at 200 MHz. The chips mainly target high-definition audio processing in

In November Altera announced the Stratix III family, its next generation of field-programmable gate arrays (FPGAs). The new devices will be fabricated in a 65 nm process and feature a number of significant architectural changes. To reduce power consumption, Altera has introduced
This week, Analog Devices introduced four new members of its Blackfin processor family: the ADSP-BF549, ‘BF548, ‘BF544, and ‘BF542. These new devices will operate at clock speeds of up to 600 MHz and are intended mainly for automotive applications that incorporate signal
In September, Texas Instruments, Inc. (TI) announced the TMS320C6720 floating-point DSP. Operating at 200 MHz and priced at a modest $5.75 (unless otherwise stated, all prices mentioned in this article are for 10,000 unit quantities), the chip is the latest and least expensive member of
On September 9th, silicon intellectual property licensor ARC made two related announcements: It unveiled a new configurable multimedia player subsystem based on its ARC600 family of cores, and announced a new partnership with Chinese silicon foundry Semiconductor Manufacturing
On June 26th Texas Instruments announced the TAS3108, a new 8-channel audio processor targeting high fidelity home and car audio. The TAS3108's predecessor was a fixed-function filter engine. Customers would specify the filter properties and receive a customized fixed-function chip. With
Say you’ve just developed a new digital signal processing algorithm—a new audio or video codec, for example. The algorithm is intended to be ported to multiple embedded processors, including general-purpose processors (like the ARM9) and digital signal processors (like the Texas
In June DSP core licensor CEVA announced CEVA-Audio, a licensable audio platform targeting high-volume audio applications such as portable audio players and home entertainment equipment. The CEVA-Audio platform is based on CEVA’s recently announced CEVA-TeakLite-II core. For an overview
