New TI Programmable DSPs Deliver 12X More Performance For Applications Ranging From Industrial Automation To Optical Networking
First 32-bit, Flash DSPs make it possible to develop high-precision control applications in record time entirely in high level C/C++ language
HOUSTON (September 4, 2001) - Two new high-precision control digital signal processors (DSPs) unveiled today from Texas Instruments Incorporated (TI) (NYSE: TXN) will reduce development time from hours to minutes while delivering up to 12x performance of any existing programmable DSP controller. The new devices, the industry's first 32-bit control DSPs with on-board Flash memory and performance up to 150 million instructions per second (MIPS), target industrial automation, optical networking and automotive control applications. www.dspvillage.com/c28xdsppr
"TI continues its aggressive investment strategy and commitment to the control market with the announcement of these two new devices in their TMS320C2000™ platform of DSPs," said Will Strauss, president of DSP market watcher Forward Concepts. "TI has focused on developing effective control solutions and now delivers a new level of high performance and integration with these software-compatible C28x- based DSPs."
Optimized for Control Applications
The new TMS320F2810 DSP and the TMS320F2812 DSP are the first catalog devices based on TI's code compatible TMS320C28x™ DSP core, which is designed exclusively for control applications and is extensible up to 400 MIPS. With an innovative unified architecture that combines the best of general-purpose processors and DSP capabilities, the C28x™ devices allow both the system and math code to be developed completely in C/C++, reducing development time from hours to minutes. Hardware and software features that help simplify development include:
- 150 MIPs
- 32-bit processing
- Efficient C/C++ compiler
- Unique "IQmath" library
- Fast and flexible interrupt management
- Control optimized peripherals
- Multiple Standard Communications ports
- Up t
- 128Kw of on-chip Flash memory
- Application-specific packaging
- Code compatibility with TMS320C24x™ generation
- eXpressDSP™
TI's TMS320C28x™ DSP delivers the industry's most integrated DSP controller while improving system reliability, flexibility and intelligence for tunable laser applications in the optical networking space. A version of the F2812 DSP that is packaged in a 179-lead microStar ball grid array (BGA) meets the tighter space requirements of optical networking. The TMS320C28x DSP is the latest addition toTI's portfolioof products designed toenable the intelligent optical networks of today and tomorrow.
Optimized for Integration
The new F2810 and F2812 DSPs offer a complete system-on-a-chip for high-precision control applications leading tosimpler more cost effective designs. The F2812 DSPs integrate 128 kilowords (kW) of Flash memory and the F2810 DSP 64 kW for reprogramming during development and in-field software updates. TI's Flash acceleration technology allows code tobe executed out of Flash at 110-120 MIPs while time-critical code requiring 150 MIPs of performance can be executed directly out of the 18kW of on-chip RAM. In addition, the F2812 DSPs offer an external memory interface with an address reach of one megawords (Mwords) for systems requiring a larger memory model.
Integration of control peripherals and communication ports in the new C28x DSP devices provides cost-efficiency and ease of design for controller applications. Optimized event managers include flexible pulse-width modulation (PWM) generators, programmable general-purpose timers and glueless capture and encoder interfaces. A 12-bit analog-to-digital converter (ADC) capable of twochannel conversions at 60 nanosecond (ns) per channel and dual sample-hold provides critical support in the completion of analog control loops. Multiple standard communication ports provide simple communications interfaces tohosts, test equipment, displays and other components. A Control Area Network (CAN) controller that is version 2.0B-compliant provides a glueless interface toCAN networks for a variety of industrial, automotive and backplane applications.
Optimized for Time
The C28x DSPs and C/C++ compiler were designed together toensure maximum efficiency of compiled code allowing designers todevelop control applications entirely in a high-level language. A tight, 16-bit instruction set generates superior code density while providing 32-bit precision. Code developed for C28x DSPs is code compatible with the C24x™ DSP generation, protecting developers software investment as they migrate their designs allowing them totake advantage of TI's newest DSP generation.
In addition tothe efficient C/C++ compiler, the C28x DSPs are equipped with 32-bit math capabilities as well as a unique math library allowing designers toport floating-point algorithms toa fixed-point machine in a matter of minutes. With the conversion of math algorithms in traditional 16-bit fixed-point machines being a laborious and time-consuming task, TI's C28x DSPs give designers the math code efficiency of DSPs with the ease and system code efficiency of general purpose processors making development of control applications faster and easier.
"TI's C2000™ DSP platform gives us the ability toprovide customers with high performance automation in industrial networking applications," said Edison Hudson, President, MetaControls, Inc. "While being code compatible with our existing C24x based products, the C28x extends the performance and software functionality toa higher level and will allow us toeasily provide our customers with wholly embedded solutions, including high level functions such as multi-axis trajectory planning. We see the C28x as the enabler for "PC-less" real-time networks for motion and process control."
More Than Outstanding DSPs
TI provides optimized system solutions for the digital control markets as well as provides industry leading DSP and analog parts, software, support, tools, reference designs/Evaluation Modules (EVM) and market knowledge, allowing OEMs toincrease revenue by simplifying development and speeding time tomarket. In addition, TI customers whoare designing applications with C28x DSPs can leverage TI digital signal processing support todecrease product development time. http://www-k.ext.ti.com/sc/technical_support/index.htm or http://www-k.ext.ti.com/sc/technical-support/knowledgebase.htm.
The C2810 and C2812 DSPs are supported by TI's eXpressDSP Real-Time Software Technology, complete with the Code Composer Studio™ Integrated Development Environment (IDE), the industry's most sophisticated DSP IDE. TI's full library of digital control and optical networking software modules, the DSP industry's largest third party network and best-in-class software development tools all add up tofaster time tomarket for the designers of high-precision control applications.
For applications requiring greater analog precision than offered on-chip, TI alsoprovides a variety of high performance data converters that easily interface with these new DSPs. For example, designers can use the 16-bit, 50-kSPS ADS8324 analog-to-digital converter for operation down to1.8-V, and the multi-channel, 16-bit ADS834x family for operation down to2.7-V. For higher resolution applications, the 24-bit, 4-channel, 20-kSPS ADS1254 delta-sigma analog-to-digital converter interfaces directly with the C28x DSPs.
Availability, packaging and pricing
Samples of the new TMS320C28x DSPs are scheduled for availability during the first quarter of 2002, with volume production scheduled tofollow in the second quarter. The F2810 DSP will be offered in a 128-lead LQFP, and the F2812 DSP in a 176-lead LQFP which is well-suited tothe production needs of industrial, automotive, commercial and consumer applications. A version of the F2812 DSP that is packaged in a 179-lead microStar ball grid array (BGA) meets the tighter space requirements of optical networking. Planned pricing per unit in quantities of 10,000 is $17.95 for the F2810 DSP and $22.95 for each version of the F2812 DSP.
