Texas Instruments Inc. (TI) is sampling the TMS320C6424 and TMS320C6421 DSPs for application in telecom enterprise gateway and IP-PBX products. The devices are upward-code-compatible with existing TMS320C6000 DSPs and can be programmed using TI's ExpressDSP software. They are supported by C6424 DSP evaluation module (EVM) and development tools.

"With the ability to process voice, video and data with ease and with native networking capabilities, these new DSPs will be a natural choice" for OEMs building DSP-based devices that connect to the Internet Protocol network, said Gerard Andrews, DSP marketing manager at TI.

The C642x DSPs are based on the TMS320C64x+ DSP core. The performance of the two chips peaks at 4,800 million multiply-accumulate operations (MMACs) at 600MHz. The C6424 and C6421 deliver a 1.6-2x boost in raw DSP processing power (such as peak 16bit MMACs). With a 50 percent price reduction, they enable more than a 2.5x price/performance improvement over previous-generation DSPs, TI said.

Riding Surf
TI is teaming with Surf Communication Solutions Ltd to provide ready-made telecom cards and a development support system for the voice and VoIP markets. The SurfExpress/PCIe and SurfRider/AMC are media-processing platforms based on TI C6000 DSPs. Both the SurfExpress/PCIe and SurfRider/AMC platforms feature the SurfDocker, a modular plug-in that carries pairs of mixed DSPs, including C642x products, and supports configurations to meet telecom needs.

Surf also offers chip-level solutions based on the C642x DSPs, which come with a multimedia processing package for telecom applications.

Avi Fisher, chief technology officer at Surf Communication Solutions, said, "The C6424 DSP enables Surf to reduce the price per channel by 50 percent and support densities of up to 60 VoIP ports or 16 VoIP ports."

At the same time, Adaptive Digital Technologies Inc. is releasing the G.PAK software suite for C642x DSPs.

Both DSPs come in 400-, 500- and 600MHz speeds. The two chips are pin-compatible, and both are available in two sizes, a 16-by-16mm and a 23-by-23mm BGA, at 0.8mm pitch and 1mm pitch, respectively.

Pricing for the C6421 DSP is $8.95 for 400MHz, $11.95 for 500MHz and $16.95 for 600MHz parts. The C6424 DSP is priced at $15.95 for 400MHz, $19.95 for 500MHz and $24.95 for 600MHz parts. The C6424 EVM is priced at $495. In addition to a Code Composer Studio IDE, DSP/BIOS kernel, Chip Support Library and audio codecs, the EVM also includes VirtualLogix's uCLinux.
