Texas Instruments Inc. offers its lowest-cost digital media processor to date, the MS320DM335, for applications driven by advanced image capture and display requirements. Powered by an ARM926EJ-STM core up to 270MHz, the DM335 digital media processor integrates a video processing subsystem (VPSS) so developers can easily add high-definition video display at 720p on their new class of portable applications, says TI.

The company adds that the DM335 processor provides the benefits of greater than 25 percent cost reduction than its predecessor, the TMS320DM355 processor. The new digital media processor is completely scalable with the DM355 processor and Digital Video Evaluation Board (DVEVM), allowing customers to re-use both hardware and software designs for their new DM335 processor focused projects. The DM335 processor also offers a compelling solution for customers creating advanced user interface display applications that do not require video compression and decompression for a fraction of the cost.

TI notes that the device delivers a sophisticated suite of capabilities allowing for flexible image capture and display. Through its user interface technology, such as a four-level on-screen display, developers are able to create picture-within-picture and video-within-video as well as innovative GUIs. This is especially important for portable products that require the use of button or touchscreen, such as portable karaoke, universal remote controls, video doorbells and electronic gaming applications.

For crisp and vibrant display images, the DM335 processor supports CCD/CMOS image sensors, resize capability and video analytics. The 1280 x 960 pixel digital LCD connection runs on a 75MHz pixel clock and supports TV composite output for increased expandability.

In addition to being pin-to-pin compatible with the DM355, the new DM335 device is also software compatible with all of TI's digital media processor devices.

For developers already creating applications based on the DM355 device, they can jump start their DM335 processor-based design by utilizing the same development kit and even use the same code for applications that do not require MPEG-4 or JPEG codec. The DM355 Digital DVEVM integrates an optimized MontaVista Linux board support package (BSP), drivers and display capture support for the VPSS to help developers easily build low-cost portable products. The DVEVM also support Windows Embedded CE 6.0.

The TMS320DM335 digital media processor is now available for $10.48 in 100 units from TI at The highly integrated device is packaged in a 13mm x 13mm, 329-pin, 0.65mm pitch BGA package. The TMDSEVM355 Digital Video Evaluation Module is now available for $495.
