Texas Instruments has introduced two digital signal processors based on its DaVinci multimedia platform for multi-channel video security, machine vision systems and imaging applications.
The company has aimed for design cost reduction with the TMS320DM647 and TMS320DM648 DSPs which it claimed includes functionality leading to a $40 reduction in video system bill of materials (BOM).
The enhanced C64x core, called the C64x+, according 
to the supplier provides 20 per cent better cycle performance, 20 to 30 per cent higher code density, twice as many 16-bit MMACs per cycle, four times the EDMA bandwidth and is 100 percent code compatible with the C64x core.
“Two extra video ports remove the need for a $7 video multiplexer, the integrated SGMII port with switch interconnects up to four devices to provide the functionality of an $8 PCI bridge, and an approximately $25 FPGA required for video preprocessing 
like colour space conversion, resizing and de-interlacing is eliminated by an on-chip VICP,” said the company.
The DM648 also offers 512kbyte of L2 cache and two Ethernet MACs with a switch while the DM647 has 256kbyte of L2 cache and one Ethernet MAC port.
These are the first DaVinci processors enabled by XDS560 Trace module, a non-intrusive, hardware-based trace tool offering improved design visibility and debug capabilities.
