The TMS320DM6446 (also referenced as DM6446) leverages TI's DaVinci™ technology to meet the networked media encode and decode application processing needs of next-generation embedded devices.

The DM6446 enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution.

The dual-core architecture of the DM6446 provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C64x+™ DSP core and an ARM926EJ-S core.

The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously.

The ARM core incorporates: A coprocessor 15 (CP15) and protection module Data and program Memory Management Units (MMUs) with table look-aside buffers. Separate 16K-byte instruction and 8K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT).

The TMS320C64x+™ DSPs are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. It is based on an enhanced version of the second-generation high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSP cores an excellent choice for digital media applications. The C64x is a code-compatible member of the C6000™ DSP platform. The TMS320C64x+ DSP is an enhancement of the C64x+™ DSP with added functionality and an expanded instruction set.

Any reference to the C64x™ DSP or C64x™ CPU also applies, unless otherwise noted, to the C64x+™ DSP and C64x+™ CPU, respectively.

With performance of up to 6480 million instructions per second (MIPS) at a clock rate of 810 MHz, the C64x+ core offers solutions to high-performance DSP programming challenges. The DSP core possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional units--two multipliers for a 32-bit result and six arithmetic logic units (ALUs). The eight functional units include instructions to accelerate the performance in video and imaging applications. The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 3240 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 6480 MMACS. For more details on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide (literature number SPRU732).

The DM6446 also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices. The DM6446 core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 256K-bit direct mapped cache and the Level 1 data cache (L1D) is a 640K-bit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 512K-bit memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two.

The peripheral set includes: 2 configurable video ports; a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module; an inter-integrated circuit (I2C) Bus interface; one audio serial port (ASP); 2 64-bit general-purpose timers each configurable as 2 independent 32-bit timers; 1 64-bit watchdog timer; up to 71-pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 UARTs with hardware handshaking support on 1 UART; 3 pulse width modulator (PWM) peripherals; and 2 external memory interfaces: an asynchronous external memory interface (EMIFA) for slower memories/peripherals, and a higher speed synchronous memory interface for DDR2.

The DM6446 device includes a Video Processing Subsystem (VPSS) with two configurable video/imaging peripherals: 1 Video Processing Front-End (VPFE) input used for video capture, 1 Video Processing Back-End (VPBE) output with imaging co-processor (VICP) used for display.

The Video Processing Front-End (VPFE) is comprised of a CCD Controller (CCDC), a Preview Engine (Previewer), Histogram Module, Auto-Exposure/White Balance/Focus Module (H3A), and Resizer. The CCDC is capable of interfacing to common video decoders, CMOS sensors, and Charge Coupled Devices (CCDs). The Previewer is a real-time image processing engine that takes raw imager data from a CMOS sensor or CCD and converts from an RGB Bayer Pattern to YUV4:2:2. The Histogram and H3A modules provide statistical information on the raw color data for use by the DM6446. The Resizer accepts image data for separate horizontal and vertical resizing from 1/4x to 4x in increments of 256/N, where N is between 64 and 1024.

The Video Processing Back-End (VPBE) is comprised of an On-Screen Display Engine (OSD) and a Video Encoder (VENC). The OSD engine is capable of handling 2 separate video windows and 2 separate OSD windows. Other configurations include 2 video windows, 1 OSD window, and 1 attribute window allowing up to 8 levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz, providing a means for composite NTSC/PAL video, S-Video, and/or Component video output. The VENC also provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of 8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs.

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM644x and the network. The DM6446 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS) support.

The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system. Once a PHY candidate has been selected by the ARM, the MDIO module transparently monitors its link state by reading the PHY status register. Link change events are stored in the MDIO module and can optionally interrupt the ARM, allowing the ARM to poll the link status of the device without continuously performing costly MDIO accesses.

The HPI, I2C, SPI, USB2.0, and VLYNQ ports allow DM6446 to easily control peripheral devices and/or communicate with host processors. The DM6446 also provides multimedia card support, MMC/SD, with SDIO support.

The DM6446 also includes a Video/Imaging Co-processor (VICP) to offload many video and imaging processing tasks from the DSP core, making more DSP MIPS available for common video and imaging algorithms. For more information on the VICP enhanced codecs, such as H.264 and MPEG4, please contact your nearest TI sales representative.

The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides listed in Section 2.8.3.1, Related Documentation From Texas Instruments.

The DM6446 has a complete set of development tools for both the ARM and DSP. These include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into source code execution.

SPRC831 — 视频影像协处理器 (VICP) 信号处理库

德州仪器 (TI) VICP 信号处理库是高度优化的软件算法的集合,它在 VICP 硬件加速器上运行。该库使应用开发人员能够有效地利用 VICP 性能,而无需将宝贵时间花在开发用于加速器的软件上。具有成熟的可用性和性能优化算法,VICP 信号处理库能够显著降低应用开发时间。DSP 上的自由 MIPS 使应用开发人员能够将更多差异化功能包含在最终应用中。

VICP 硬件加速器是一个并行 MAC 引擎。通过执行各种计算密集型任务,该加速器能够非常有效地提高 DSP 的性能,这完全归功于它的灵活架构。

VICP 支持各种算法以便能提供其它 DSP 资源
  • 矩阵运算/阵列运算:
    • 示例:矩阵乘法/转置。块加法/平均值/方差
    • 示例:阵列乘法/加法/Fillmem。阵列标量操作
    • 示例:查找表
  • 数字信号处理操作:
    • 示例:1D、2D FIR 滤波
    • 示例:卷积、关联性
  • 数字图像和视频处理功能
    • 示例:α 混成、颜色空间变换
    • 示例:图像旋转、图像压缩/解压
    • 示例:媒体滤波

VICP 信号处理库还为系统提供了用于在应用中简化 VICP 硬件加速器功能的集成的功能。这些功能包括:
  • 在同步或异步模式中执行 API 的能力 在同步模式中,系统会阻止对库 API 的所有调用,直到 VICP 的处理时间结束。在异步模式中,将立即返回对库 API 的调用。通过使用中断,DSP 将在处理结束后收到通知。
  • VICP 信号处理库可与系统 DMA 管理器进行内部连接,以便为 VICP DMA 提供所需服务。这将降低系统集成的复杂性。
  • 该库还可以处理片上高速缓存和外部存储同步以确保数据准确性。

VICP 信号处理器包括所有受支持的 API 的 C 等效实施。应用开发人员可以使用 C 等效实施来更好地了解每个 API 所实现的信号处理功能。它为每个 API 提供了一个参考测试台。该测试台使用户能够了解这些 API 的正确使用方法。该测试台基于领先的 DSP-BIOS 实时操作系统进行构建。因此,任何测试台甚至都可以作为使用 VICP 进行应用开发的起点使用。

在 v3.0 中,通过以下途径提供附加功能和定制:
  • 访问 VICP 计算单元和 VICP 调度单元(以前无法在 v2.0 中访问)
  • VICP 计算单元库,它提供了 30 多个函数,客户可以将这些函数链接在一起以生成更多定制算法
  • VICP 单元库,它提供了将多个函数链接在一起所需的基础设施,无需添加 DMA 带宽,并且最大程度地简化了设置
