TI Delivers Two System-Level DSPs Integrating a Power-efficient Programmable TMS320™ DSP, RISC Processor and Support for Embedded Operating Systems
Immediate availability of application software, development tools and new system-level DSPs reduce cost/size by 40 percent and power consumption by 30 percent while accelerating time to market
HOUSTON (December 10, 2001) - Designers of real-time applications can immediately realize a 40 percent reduction in cost and size while reducing power consumption nearly 30 percent with the introduction of two new highly integrated, system-level digital signal processors (DSPs) from Texas Instruments Incorporated (TI) (NYSE:TXN). The devices combine the world's most popular programmable TMS320C5000(tm) DSP with the ARM7 Thumb reduced-instruction-set-computing (RISC) processor and support for some of the most prolific embedded operating systems. The synergy of these technologies will speed to market real-time applications including text-to-speech, wireless data, voice recognition and networked security. For more information see (dspvillage.ti.com/c547x).
The new programmable TI TMS320C5470 and TMS320C5471 DSPs are in production today and are supported by the eXpressDSP™ suite of easy-to-use development tools, including the DSP/BIOS™ real-time scalable kernel. In addition, RidgeRun™'s embedded RISC operating system, DSPLinux™, supports the devices. Designers can anticipate the release of Accelerated Technology's Nucleus PLUS and Wind River VxWorks® real-time operating system (RTOS) support to be added in 2002.
System-level integration provides for significant savings in board space, power consumption and cost over embedded solutions that use a discrete DSP and RISC. For example, in a typical application, a discrete solution employing a DSP, RISC processor, glue logic and memory would require about 440 mm2 of board space, consume 240 mW of power and cost about $32. The same application employing the C5471 DSP would require only 256 mm2 of board space, consume 175 mW of power and cost less than $18. These savings are complemented by a reduction in design complexity and increased production throughput due to a reduction in parts.
Both system-level devices are based on a TI TMS320C54x™ DSP operating at 100 megahertz (MHz) with 100 millions of instructions per second (MIPS) processing power, 72 Kwords of RAM, (8 Kwords of RAM shared with the ARM7) and two multichannel buffered serial ports. The ARM7 provides processing power of 47.5 MHz, single-port 10/100 Base-T Ethernet, general-purpose I/O, two universal asynchronous receiver/transmitters (UART), a serial port interface, I2C interface, and 16 Kbytes of zero-wait-state synchronous random access memory (SRAM).
Integrated Peripheral and O/S Communication Stack Accelerate Time to Market
The C5470 and C5471 DSPs offer a rich set of communication peripherals and readily available communications stacks for 10/100 Ethernet, home phone line network alliance (HPNA), Bluetooth and 802.11b wireless LAN, allowing designers to rapidly bring new products to market that serve many applications. The C5470 or C5471 DSP can seamlessly interface to TI's BNS6030 Bluetooth chip, or TI's ACX100 802.11b chipset for wireless connectivity. And the integrated 10/100 Ethernet media access controller (MAC) and media independent interface (MII) provide connectivity to Ethernet or HPNA networks.
"With TI's TMS320C54x DSP now available with a RISC processor on a single chip, significant benefits are immediately recognized," said Dennis Barrett, TI product marketing manager. "In a given application, each task required can be targeted toward the right processing engine for increased system performance."
In a text-to-speech system, this means that the DSP is dedicated to text-to-speech synthesis, while the RISC processor performs linguistic processing functions. In a client networking application, the DSP performs real-time signal processing, while the RISC processor orchestrates system control.
Combination of silicon, software tools and support enable fast, robust system development
TI's eXpressDSP real-time software and tools offers full heterogeneous code development and debug for the ARM7 and TMS320C5000 DSP in the recently-announced Code Composer Studio™ IDEv2 for the OMAP™ platform. In addition to Code Composer Studio IDE v2 for OMAP, eXpressDSP also includes integrated support for DSP/BIOS running on the DSP, a real-time operating system with a multithreading kernel, real-time analysis and peripheral configuration libraries. Evaluation modules are also available for the C5470 and C5471 DSPs from Spectrum Digital.
A fully integrated GDB Linux development environment for the C5471 DSP is provided by RidgeRun's DSPLinux. RidgeRun's DSPLinux operating system and board support package fully bundled with emulation technology and hardware target evaluation modules (EVM) is available through Spectrum Digital. Board support packages (BSPs) for Accelerated Technology's Nucleus operating system as well as for the Wind River Tornado® integrated development environment and VxWorks RTOS will be made available in 2002.
The system-level integration of the C5470 and C5471 DSPs accelerate time-to-market for embedded and connected applications by providing robust silicon with a rich peripheral set, support for Linux, VxWorks and Nucleus operating systems for the ARM7, and DSP/BIOS from TI for the C54x™ DSP. These choices of operating systems provide designers instant availability to more than 400 eXpressDSP-compliant algorithms from TI's third-party network and over 1000 existing operating system middleware software packages.
Availability
The C5470 and C5471 DSPs are available today in production quantities. The C5470 DSP is priced at $15.50 and the C5471 DSP at $17.57 (10,000-unit quantities). The C5470/C5471 DSP development board with DSPLinux is also available today from Spectrum Digital. www.spectrumdigital.com
