数字信号处理器和控制器 - DSP, DSC DaVinci Digital Media Processor

TMS320DM814x DaVinci video processors are highly integrated, programmable platforms that leverage the DaVinci processor technology to meet the processing needs of the following applications to name a few: HD Video Conferencing - Skype endpoints Video Surveillance DVRs IP Netcam Digital Signage Media Players and Adapters Mobile Medical Imaging Network Projectors Home Audio and Video Equipment

The device enables Original-Equipment Manufacturers OEMs and Original-Design Manufacturers ODMs 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 TMS320DM814x DaVinci video processors also present OEMs and ODMs with new levels of processor scalability and software reuse. An OEM or ODM that used the AM387x processors in a design and can make a similar product with added features could scale up to the pin-compatible and software-compatible TMS320DM814x processors from . The TMS320DM814x DaVinci video processors add a powerful C674x DSP core along with a video encoder and decoder to the hardware on the AM38x. Additionally, OEMs or ODMs that have used the AM387x or DM814x processors and find a need for a faster ARM and DSP core performance could scale up to the software-compatible AM389x or TMS320DM816x devices with higher core speeds.

Programmability is provided by an ARM Cortex-A8 RISC CPU with Neon extension, TI C674x VLIW floating-point DSP core, and high-definition video and imaging coprocessors. The ARM lets developers keep control functions separate from A/V algorithms programmed on the DSP and coprocessors, thus reducing the complexity of the system software. The ARM Cortex-A8 32-Bit RISC Core with Neon floating-point extension includes: 32KB of Instruction cache; 32KB of Data cache; 512KB of L2 Cache; 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 of the peripherals, see the related sections in this document and the associated peripheral reference guides. The peripheral set includes: HD Video Processing Subsystem Dual Port Gigabit Ethernet MACs 10/100/1000 Mbps [Ethernet Switch] with MII/RMII/GMII/RGMII and MDIO interface supporting IEEE 1588 Time-Stamping and Industrial Ethernet ProtocolsTwo USB ports with integrated 2.0 PHY PCIe x1 GEN2 Compliant interfaceTwo 10-serializer McASP audio serial ports with DIT modeFour quad-serilaizer McASP audio serial ports with DIT modeOne McBSP multichannel buffered serial portSix UARTs with IrDA and CIR supportFour SPI serial interfacesThree MMC/SD/SDIO serial interfacesFour I2C master and slave interfaces Parallel Camera Interface CAMUp to 128 General-Purpose I/Os GPIOsEight 32-bit general-purpose timers System watchdog timer Dual DDR2, and DDR3 SDRAM interfacesFlexible 8- or 16-bit asynchronous memory interfaceTwo Controller Area Network DCAN modulesSpin LockMailboxSerial Hard Disk Drive Interface SATA 300

The TMS320DM814x DaVinci video processors also include a high-definition video and imaging coprocessor 2 HDVICP2, and an SGX530 3D graphics engine to off-load many video and imaging processing tasks from the DSP core, making more DSP MIPS available for common video and imaging algorithms. Additionally, it has a complete set of development tools for both the ARM and DSP, which include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Microsoft® Windows® debugger interface for visibility into source code execution.

The C674x DSP core is the high-performance floating-point DSP generation in the TMS320C6000 DSP platform and is code-compatible with previous generation C64x Fixed-Point and C67x Floating-Point DSP generation. The C674x Floating-Point DSP processor uses 32KB of L1 program memory with EDC and 32KB of L1 data memory. Up to 32KB of L1P can be configured as program cache. The remaining memory is noncacheable no-wait-state program memory. Up to 32KB of L1D can be configured as data cache. The remaining memory is noncacheable no-wait-state data memory. The DSP has 256KB of L2 RAM with ECC, which can be defined as SRAM, L2 cache, or a combination of both. All C674x L3 and off-chip memory accesses are routed through an MMU.
