The Texas Instruments DaVinci is a family of system on a chip processors that are primarily used in embedded video and vision applications.〔(Overview - DaVinci Processors )〕〔(Wiki - DaVinci Overview )〕 Many of the processors in the family combine a DSP core based on the TMS320 C6000 VLIW DSP family and an ARM CPU core into a single system on chip. By using both a general-purpose processor and a DSP, the control and media portions can both be executed by processors that excel at their respective tasks. Later chips in the family included DSP only and ARM only processors. All the later chips integrate several accelerators to offload commodity application specific processing from the processor cores to dedicated accelerators. Most notable among these are HDVICP, an H.264, SVC and MPEG-4 compression and decompression engine, ISP, an accelerator engine with sophisticated methods for enhancing video, primarily input from camera sensors and an OSD engine for display acceleration. Some of the newest processors also integrate a vision coprocessor in the SoC. == History == DaVinci processors were introduced at a time when embedded processors with homogeneous processor cores were widely used. These processors were based either on cores that could do signal processing optimally, like DSPs or GPUs or based on cores that could do general purpose processing optimally, like, powerPC, ARM, StrongARM and so on. By using both a general-purpose processor and a DSP on a single chip, the control and media portions can both be executed by processors that excel at their respective tasks. By providing a bundled offering with system and application software, evaluation modules and debug tools based on Code Composer Studio, TI DaVinci processors were intended to win over a broader set of customers looking to add video feature to their electronic products. TI announced its first DaVinci branded video processors, the DM6443 and DM6446, on 5 December 2005.〔(EDN: TI Unveils DaVinci Development Kit for Video, DSPs )〕〔(Linuxgizmos: Linux drives next-gen video gadget chip )〕〔(Embedded.com: Single-chip systems make digital video easy )〕〔(BDTI: TI Launches First “DaVinci” Video Processors )〕〔(EETimes: December Newsletter: TI Launches First "DaVinci" Video Processors )〕 A year later, TI followed up with DSP only versions of the chips in the family, called DM643x (DM6431, DM6433, DM6435, DM6437).〔(EDN: Digital video processor breaks $10 )〕〔(Texas Instruments Announces DaVinci Family Extensions )〕 On January 15, 2007, TI announced DM6441 that is pin-pin compatible with DM6446, but a lower end version〔(TI's Latest DaVinci Processor Drives Growth of Portable Digital Video Applications )〕 With increased investment and significant focus on the DaVinci product line, following products were announced: * May 21, 2007 — TMS320DM648 — Processor offering $40 reduction in BOM for security applications〔(Texas Instruments DaVinci(TM) Technology Doubles System Performance with a $40 System BOM Reduction for Video Security and Surveillance Applications )〕 * Sep 4, 2007 — TMS320DM355 — Sub $10 ARM+co-processor chip for MPEG-4 encode/decode〔(Texas Instruments Launches New Low-Cost DaVinci™ Processor to Spur Growth of Portable, HD Video Applications )〕 * Dec 30, 2007 — TMS320DM6467 — 10x performance improvement over DM6446〔(TI Delivers First Single-Chip, Real-Time HD Video Transcoding Solution with DaVinci™ Technology )〕 * Jul 18, 2008 — TMS320DM335 — ISP only version of DM355〔(Design costs for portable display electronics drop with TI's lowest cost digital media processor )〕 * Nov 18, 2008 — TMS320DM357 — Low cost realtime D1 H.264 video encode〔(New digital media processor from Texas Instruments provides H.264 at D1 resolution for professional quality video on low-cost consumer video products )〕 * March 3, 2009 — TMS320DM365 — Sub $10 ARM+co-processor chip for 720p30 and 1080p H.264 encode/decode〔(New TMS320DM365 processor from Texas Instruments provides pixel-perfect 1080p H.264 video flexibility without the design complexity )〕 * March 18, 2010 — TMS320DM8168 — 36x channels of realtime D-1 H.264 encode/decode or 6x channels of realtime HD H.264 encode/decode〔(New DM8168 DaVinci™ video SoC from Texas Instruments offers best-in-class embedded video performance for video surveillance and video communications )〕 * April 14, 2010 — TMS320DM368 — Pin-pin compatible processor with DM365 that can do 1080p30 H.264 encode/decode〔(New TMS320DM368 DaVinci™ video processor from Texas Instruments offers full HD video with a boost in ARM® performance for advanced video applications )〕 * May 10, 2010 — DMVA2 — Pin-pin compatible processor with DM365 and DM368 that can do analytics in addition to H.264 compression〔(Texas Instruments launches DaVinci™ DMVA2 video processor, the first megapixel IP camera SoC with smart analytics )〕 * Mar 1, 2011 — TMS320DM8148 — 12x channels of D-1 H.264 encode performance with DSP for analytics〔(Can you see us now?
