Highest Performing Floating-Point DSP From TI Offers 33 Percent Performance Increase

26-Mar-04

Continuing to meet the increased processing demands of the professional audio, high-end consumer audio, industrial and medical industries, Texas Instruments Incorporated (TI) announced today a 300 MHz TMS320C6713 digital signal processor (DSP) that offers a 33 percent performance increase over the existing 225 MHz C6713 processor. This new DSP provides 1800 MFLOPS (Million Floating-Point Operations Per Second) for high-performance signal-processing applications that need the precision and dynamic range offered by floating-point calculations. Typical audio applications include high-speed encoding, multichannel broadcast encoding, digital mixing, and high-quality effects creation.Additionally, customers have found that this product is a good fit to meet their specifications for a host of medical and industrial applications, including semi-conductor manufacturing equipment. The new 300 MHz C6713 DSP is package and pin-out compatible with the 225 MHz C6713 DSP processor, making drop-in replacement straightforward and simple. Also, application code can be reused since the new C6713 is code compatible with the TMS320C6711 and other C6713 devices already deployed in the market today. Supporting the C6713 DSP is a C6713 DSP Starter Kit (DSK) that includes TIís comprehensive Code Composer Studio (CC Studio) v2.2 Integrated Development Environment (IDE), providing the best floating-point development environment in the industry.A cornerstone of the C6713 digital signal processor is its audio-friendly I/O that allows easy interconnects to bus standards associated with typical audio systems. This convenient I/O capability is enabled by two I2C (Inter-Integrated Circuit Bus) multi-master and slave interfaces as well as two McASPs (Multi-Channel Audio Serial Ports) each offering independent Tx and Rx clock zones, eight serial data pins, extensive error checking and recovery, support of I2S and other bit stream formats. The processor also supports an integrated Digital Audio Interface Transmitter (DIT) with 16 transmit pins, enhanced channel status/user data and support for S/PDIF, IEC60958-1, AES-3 and CP-430. In many performance driven floating point applications, multiple channels of data are processed on the same DSP. The 33-percent increase in processing power in the newest version of the C6713 will allow customers to add more channels per DSP without having to redesign existing hardware. ìDolby has been cooperating with Lyrtech and Texas Instruments to get the Dolby Digital Professional Encoder ported to the 225 MHz version of the TMS320C6713,î said Sabine Jennings, Licensing Program Manager, Dolby. ìThe addition of the 300 MHz part to the C67x generation will allow our customers to add a stereo encode pair to their end systems without increasing their footprint.îTI also offers a wide range of high-performance analog components for audio applications with a variety of amplifiers, including low-power Class-D audio amplifiers, high-precision analog-to-digital (ADC) and digital-to-analog converters (DAC), single and dual output Low Drop Out regulators (LDOs), low-voltage switching DC/DC converters and supply voltage supervisors. Further enabling developers to develop applications quickly and easily is TI's extensive C67x DSP Library and Fast C67x DSP Run-Time Support Library, which are free and downloadable from the Web and allow designers to develop applications quickly and easily. Additionally, the C67x generation is supported by TI's eXpressDSP software and development tools including the CCStudio v2.2 IDE, DSP/BIOS(TM) real-time kernel and a wide range of eXpressDSP-compliant software and hardware from the DSP industry's most comprehensive third-party network.Housed in a 256-pin, 27mm2 Ball Grid Array (BGA), the C6713-300 DSP is sampling now with volume production in Q2 of 2004. Pricing is $34.29 (10Ku).For more information, visit http://www.ti.com.
