DM383 DaVinci Digital Media Processors are a highly integrated, cost-effective, low-power, programmable platform that leverages TI’s DaVinci processor technology to meet the processing needs of Car Black Box Digital Video Recorders, Portable Digital Video Recorders, and similar devices in SD and HD resolutions. The Programmable High-Definition Video Image Processor of the device supports 1080p60 of real time H.264BP/MP/HP video encode or decode. The included best-in-class H.264 encoder provides high-quality video encode for the lowest possible bit rate under all conditions, reducing valuable storage space to a minimum. In addition, the device also supports other video codecs such as MJPEG, MPEG-2, and MPEG-4. The device provides a full set of video preprocessing and postprocessing functions to ensure the best video quality. The low power consumption and high performance of the device makes it particularly suitable for portable and automotive applications.
The device enables original-design manufacturers (ODMs) and after-market manufacturers to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance through the maximum flexibility of a fully integrated mixed processor solution. The device also combines programmable video and audio processing with a highly integrated peripheral set.
The device processors include a high-definition video and imaging coprocessor 2 (HDVICP2), to off-load many video and imaging processing tasks for common video and imaging algorithms. Programmability is provided by an ARM Cortex-A8 RISC CPU with NEON extension and high-definition video and imaging coprocessors. The ARM lets developers separate control functions from A/V algorithms programmed on coprocessors, thus reducing the complexity of the system software. The ARM Cortex-A8 32-bit RISC processor with NEON floating-point extension includes: 32KB of instruction cache; 32KB of data cache; 256KB of L2 cache with ECC; 48KB of boot ROM; and 64KB of RAM.
The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each peripheral, see the related sections in this document and the associated peripheral reference guides. The peripheral set includes: HD Video Processing Subsystem; two USB ports with integrated 2.0 PHY; two serializer McASP audio serial ports (with DIT mode); three UARTs with IrDA and CIR support; four SPI serial interfaces; a CSI2 serial connection; three MMC/SD/SDIO serial interfaces; four I2C master and slave interfaces; a parallel camera interface (CAM); up to 125 general-purpose I/Os (GPIOs); eight 32-bit general-purpose timers; system watchdog timer; DDR2/DDR3/DDR3L SDRAM interface; flexible 8- or 16-bit asynchronous memory interface; two Controller Area Network (DCAN) modules; Serial ATA (SATA) 3.0 Gbps controller with integrated PHY; a Spin Lock; and Mailbox.
Additionally, TI provides a complete set of development tools for the ARM which include C compilers and a Microsoft® Windows® debugger interface for visibility into source code execution.
