Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
Digital cameras designed with the new platform will allow consumers to capture high-resolution still images and enjoy real-time PC video from the same device.
The new TMS320DSC25 programmable DSP solution extends the performance and functionality of TI's successful TMS320DSC21 platform, providing system designers with the means to improve and differentiate their digital camera products.
The new device supports the capture of still images at up to 3Mpixel in less than a second, and it encodes and decodes CIF resolution (352 x 288) MPEG-4 I+P frame video at 20frame/s.

TI's support features serve to make system development easier and speed time to market.
Software modules will be available for all major video-imaging compression standards, including JPEG, motion-JPEG, MPEG, MPEG-4, H.263, as well as audio standards such as MP3 and Advanced Audio Coding (AAC), as well as datacommunications standards such as USB and RS-232.
In addition, the DSC25 is supported by TI's eXpressDSP real-time software technology, which includes the Code Composer Studio integrated development environment, the DSP/BIOS real-time kernel, the TMS320 DSP algorithm standard for interoperability and reuse and the industry's largest base of third-party software modules.
Samples of TI's DSC25 DSP solution are available now, with volume production currently scheduled for Spring 2002.
Evaluation modules are expected to be available in the first quarter of 2002 to help camera OEMs begin development on new systems.
The DSC25 solution in quantities of 100 thousand units or more is expected to be less than $20 each.
