Single-Chip, Real-Time HD Video Transcoding Processor with Integrated ARM and DSP Cores
Texas Instruments is offering a DaVinci technology digital media processor for video transcoding in media gateways, multi-point control units, digital media adaptors, video security DVRs and IP set-top boxes. Wrapped with development tools and digital media software, the TMS320DM6467 processor is a DSP-based system-on-chip (SoC) specifically tuned for real-time, multi-format, high-definition (HD) video transcoding. Integrating an ARM926EJ-S core and 600 MHz C64x+ DSP core along with a high-definition video co-processor, conversion engine and targeted video port interfaces, the system performs simultaneous, multi-format HD encode, decode and transcoding up to H.264 HP@L4 (1080p 30fps, 1080i 60fps, 720p 60fps). The DM6467 processor integrates the ARM and DSP core along with High-Definition Video/Imaging Co-Processors (HD-VICP), video data conversion engine and targeted video port interfaces. The HD-VICP offers more than three GHz of DSP processing through dedicated accelerators for HD 1080i H.264 high profile transcoding, while the video data conversion engine manages video processing tasks, including downscaling, chroma sampling and menu overlay functionality. Less than 300 MHz of the DSP core is used to manage the multi-format video transcoding, leaving the rest of the DSP headroom available for additional application performance. While the DM6467 targets markets such as media gateways and MCUs where transcoding is a requirement, the DM6467 is appropriate in video telephony, or video security markets where multiple channels of standard definition encoding is important. The device also includes industry standard PCI bus and gigabit Ethernet among the connectivity peripherals.
