Low-power DSP certified for USB 2.0
The TMS320C5509 DSP from Texas Instruments has achieved Universal Serial Bus (USB) 2.0 full-speed certification from the USB Implementers Forum (USB-IF) compliance programme.
Free software puts imaging functions on DSPs
Texas Instruments has released a software library of 21 imaging functions for its TMS320C5510 and TMS320C5509 DSPs.
TI's C5509 DSP incorporates functions that would otherwise need to be enabled by external devices, reducing board space, parts count, and overall product cost.
This integration combined with the inherent power efficiency of the TMS320C55x DSP improves battery life up to 70% and allows the end product to offer more features in a smaller footprint.
Peripheral features include: a USB 1.1 port for direct connection to a PC; a 10bit ADC to enable battery monitoring and button interfaces; an I2C interface to microcontrollers and codecs for interchip communication; three multichannel buffered serial ports for full-duplex communication; interfaces for the most popular removable data storage formats - Sony Memory Stick and MMC/SD; accommodation of intellectual property protection; and 64bit device ID, secure ROM and disconnect options for JTAG access.

DSPs take charge of the last (wireless) mile
Soma Networks is using TI's DSPs in Somaport 300 wireless broadband gateway modems and Soma Macro basestations to bring its last-mile technology to customers around the world.
Other features of the C5509 DSP include 32Kword of dual-access SRAM; 96Kword of single-access SRAM; 32Kword of ROM; a six-channel DMA; an enhanced 16bit host port interface; a watchdog timer; real-time clock with 32kHz crystal input and separate power supply; and two 20bit general-purpose timers.
The C5509 device is supported by eXpressDSP real-time software technology.
This extensive suite of tools features the Code Composer Studio integrated development environment; the DSP/BIOS real-time kernel; the TMS320 DSP Algorithm Standard and a large and growing range of application software from TI's 400-member third-party network of developers.
Samples of the TMS320C5509 DSP are available today in 144-pin LQFP and 179-pin MicroStar BGA packages.
Full production begins in the first quarter of 2002 at a price of $18 (10,000 qty).
The C5509 DSP evaluation module (EVM) is available from Spectrum Digital (www.spectrumdigital.com), a TI third party, for a limited time at $995.
