Texas Instruments Inc (TI) has announced the industry's lowest cost floating-point DSP, the TMS320C6720 DSP, designed for cost-sensitive applications, such as musical instruments, medical, biometrics, radio broadcasting, audio conferencing, instrumentation and industrial applications .

The C67x+ DSP generation-based core is a C-efficient, VLIW architecture that offers significant performance improvements. At a real-world price/performance ratio comparable to any floating-point DSP on the market, vendors can now choose the optimal DSP for their high-quality products with the confidence of selecting the most widely-deployed DSP vendor.

The C6720 DSP, which runs at 200MHz, is pin for pin compatible with the TMS320C6722 and TMS320C6726 DSPs, providing a scaleable migration path for developers. Additionally, this device has 64KB of on-chip RAM, a 32KB instruction cache, and a 384KB ROM. This ROM is preloaded with DSP/BIOS, a real-time DSP kernel, as well as optimised DSP libraries of commonly used functions. The device also features the flexible and powerful dMAX DMA engine, which lifts application performance by significantly off-loading input/output (I/O) processing tasks from the DSP core.

This low-cost DSP arms vendors and original equipment manufacturers with the ability to deliver end products to customers faster. By offering an affordable DSP that developers can both prototype as well as implement, TI's C6720 DSP eliminates the need to convert floating-point prototypes into fixed-point designs, decreasing time-to-market for designers.

The C6720 DSP is fully supported by a number of TI development tools and kits and extensive TI DSP Third Party Network. Customers are already leveraging the Lyrtech-designed Professional Audio Development Kit (PADK), which enables developers to quickly evaluate the performance of the C672x DSP generation and begin product development immediately. TI also offers DSP development tools such as Code Composer Studio Integrated Development Environment, which eliminates the need for assembly code and creates an easy-to-maintain code base.

With the release of the C6720 DSP, coupled with the already established C6722, C6726 and C6727 DSPs, TI extends its scaleable family of floating-point DSP, giving vendors a broad range of signal processors that meet their various needs. Never before have developers of medical, biometric and audio applications been able to select a single floating-point DSP architecture for a full range of end products, from low-end to high-end.

"We believe that our customers care about the total system cost of their designs," said Gerard Andrews, world-wide floating point DSP product manager, Texas Instruments. "By offering low priced floating point DSPs that are preloaded with often used software like DSP/BIOS and that feature a rich peripheral set including a 16-bit External Memory Interface, TI is demonstrating its commitment to helping our customers dramatically reduce system cost."

TMS320C6720 DSPs are sampling immediately. The C6720 DSP at 200MHz is priced at Rs.265.71 ($5.75) in production volumes. The PADK also is available now from starting at Rs.92,188.95 ($1,995).
