Module brings multiple DSPs to bear on video

The SigDM642 is a novel multiprocessor/multichannel video module based on the Texas Instruments TMS320DM642 digital media processor.

The SigDM642 is a novel multiprocessor/multichannel video module based on the Texas Instruments TMS320DM642 digital media processor.

The module provides a multiprocessor, highly integrated, low-power-consumption DSP solution.

The modular approach to multiple digital signal processing offers a very small form factor, high channel density and performance, low cost and several other advantages for OEM products.

The SigDM642 module includes up to three DM642s, one C6711/C6713 DSP, 2, 4 or 8M x 32bit SDRAM per processor, two fully independent video ADCs and video DACs and an Ethernet PHY interface at 10/100Mbit/s.

The module has a very small form factor, approximately 60 x 80mm, and fits into a 72-pin SODIMM socket.

It works with a range of PCI and PC/104 motherboards also available from Kane Computing.

Applications for the SigDM642-SODIMM module include video digitisation, DVDs, surveillance and security, PC video, HDTV, videoconferencing, VCRs, LCD screens, projectors and flat panel displays.

The modular approach is particularly well suited to providing a scalable solution for various markets including high-end consumer electronics, public sector and defence electronics, telecomms and video-over-Internet equipment applications that require a high number of channels and/or image processing such as popular compression algorithms.

The DM642 has three on-chip video ports, which provide a glueless interface to common video decoder and encoder devices, and support multiple resolutions and video format standards.

The DM642 on-chip video ports include a VCXO interpolated control port (VIC) and support for audio/video synchronisation.
