TI floating point DSCs enable greener industrial apps
Helping industrial control designers increase energy efficiency and system performance, Texas Instruments announced what it's calling the industry's first floating point digital signal controllers (DSCs). The new TMS320F2833x devices provide 300 million floating point instructions per second (MFLOPS) performance at 150 MHz while providing the lower costs typically associated with fixed point processors.
Houston, TX —Helping industrial control designers increase energy efficiency and system performance, Texas Instruments announced what it’s calling the industry’s first floating point digital signal controllers (DSCs). The new TMS320F2833x devices provide 300 million floating point instructions per second (MFLOPS) performance at 150 MHz while providing the lower costs typically associated with fixed point processors.des greater performance for automotive radar applications.

Many solar inverter manufacturers use TI DSCs and they maximize their systems to peak efficiency through Maximum Power Point Tracking (MPPT) algorithms and dynamic algorithm adjustments during various load conditions, including cloudy and low light days.mputer numerical control (CNC) machines using AC induction motors can also achieve finer control and increased dynamic range. Systems designers using AC servo motors can now specify smaller, more energy-efficient motors.
Overall system bandwidth is also increased with the addition of a six-channel direct memory access (DMA) controller that offloads the central processing unit (CPU) from servicing the ultra-fast, on-chip analog-to-digital converter (ADC) along with user-configurable 16- or 32-bit external memory interface and high-speed serial ports. All F2833x controllers are said to offer exceptional system integration for single-chip control applications from signal input to high-resolution control output. The on-chip 12-bit, 16-channel ADC operates at 12.5 mega-samples per second.
The F2833x controller series features up to 18 pulse width modulation (PWM) channels, six of which include TI’s unique high-resolution PWM (HRPWM) technology with 150 pico-seconds (ps) resolution. Communication interfaces include CAN, I2C, UART, SPI and TI’s Multi-channel Buffered Serial Ports (McBSP).
F2833x controllers are fully software compatible with all previous TMS320C28x controllers. Samples of the F28335, F28334, and F28332 devices will be available in September 2007 and will be fully AEC Q-100 qualified for automotive applications. The F2833x devices will also be supported by TI’s TMS320C2000 Digital Motor Control and Digital Power Supply software libraries . This free, fully documented software aides developers in quickly prototyping a motor control or digital power system using C2000 controllers.
