DM3730, DM3725 Digital Media Processors The DM37x generation of high-performance, applications processors are based on the enhanced device architecture and are integrated on TI’s advanced 45-nm process technology. This architecture is designed to provide best in class ARM and Graphics performance while delivering low power consumption. This balance of performance and power allow the device to support the following example applications: Portable Data Terminals Navigation Auto Infotainment Gaming Medical Imaging Home Automation Human Interface Industrial Control Test and Measurement Single board Computers The device can support numerous HLOS and RTOS solutions including Linux and Windows Embedded CE which are available directly from TI. DM37x主要特性: DM3730, DM3725 Digital Media Processors: Compatible with OMAP™ 3 Architecture ARM® microprocessor (MPU) Subsystem Up to 1-GHz ARM® Cortex™-A8 Core, Also supports 300, 600, and 800-MHz NEON SIMD Coprocessor High Performance Image, Video, Audio (IVA2.2™) Accelerator Subsystem Up to 800-MHz TMS320C64x+™ DSP Core Enhanced Direct Memory Access (EDMA) Controller (128 Independent Channels) Video Hardware Accelerators POWER SGX™ Graphics Accelerator (DM3730 only) Tile Based Acrchitecture Delivering up to 20 MPoly/sec Universal Scalable Shader Engine: Multi-threaded Engine Incorporating Pixel and Vertex Shader Functionality Industry Standard API Support: OpenGLES 1.1 and 2.0, OpenVG1.0 Fine Grained Task Switching, Load Balancing, and Power Management Programmable High Quality Image Anti-Aliasing Advanced Very-Long-Instruction-Word (VLIW) TMS320C64x+™ DSP Core Eight Highly Independent Functional Units Six ALUs (32-/40-Bit); Each Supports Single 32- bit, Dual 16-bit, or Quad 8-bit, Arithmetic per Clock Cycle Two Multipliers Support Four 16 × 16-Bit Multiplies (32-Bit Results) per Clock Cycle or Eight 8 × 8-bit Multiplies (16-Bit Results) per Clock Cycle Load-Store Architecture With Non-Aligned Support  图1.DM3730/25功能方框图 AM/DM37x评估模块(EVM) Developed with Mistral, the AM/DM37x Evaluation Module (EVM) enables developers to immediately start evaluating AM37x or DM37x processors (DM3730, DM3725, AM3715, AM3703) and begin building solutions, including portable multimedia, portable data terminals, portable medical equipment, portable communications, home and building automation, navigation systems, test and measurement, smart displays and human machine interaction (HMI) industrial interfaces amongst many others. The AM37x EVM is based on TI’s AM3715 applications processor. The Hynix memory is interfaced to the AM3715 processor via Package-On-Package technology. The Hynix PoP memory supports 2Gbit NAND flash and 2 Gbit Mobile DDR SDRAM. The DDR memory and NAND Flash are connected to SDRAM controller (SDRC) and General Purpose memory Controller (GPMC) interfaces of processor respectively. It is also equipped with a 3.7” TFT LCD module. This LCD Module is interfaced to the Display subsystem (DSS) interface of the processor. Analog Video outputs of EVM support both Composite TV (CVBS) output and Svideo output on the main board. The CVBS or S-Video Outputs are available on respective connector by default. AM37x EVM supports multiple video input options through AM3715’s camera port. Any one of the below interface shall be active at a given point of time. 1. S-Video Input, digitized through Video decoder (TVP5146PFP) 2. Composite Video Input through Video decoder (TVP5146PFP) 3. Component Video Input through Video decoder (TVP5146PFP) 4. Camera Interface – 26-Pin camera connector to support Micron Camera Module 5. Camera Interface – Provision for LI-3M02CM camera module The EVM has a SD/MMC slot using SD/MMC1 interface on the main board. And the SD/MMC2 interface is routed to the expansion connector. The EVM has a 10/100 Mbps Ethernet interface using an external MAC/PHY controller LAN 9220 which is interfaced to the AM3715 via the GPMC interface. The EVM supports three UART (UART 1, 2 and 3) interfaces via two serial ports on the main board. High Speed USB OTG interface is supported on the EVM Main Board via an onboard external USB transceiver. High Speed USB HOST (USB2) interface is supported on the EVM Main Board via an onboard external USB transceiver. One Stereo Line IN and Stereo Headset OUT audio interface is supported through the audio codec on the TPS65950 device. The audio codec on the power module is controlled by internal registers that can be accessed through high-speed I2C interface. The EVM includes 11 status LEDs, 2 user DIP switches and 16 push button switches.It supports the standard 14-pin JTAG and ETM debug interfaces. The EVM is designed to work with TI’s Code Composer Studio development, or standard GDB tool environments. For more details refer Getting Start Guide. The EVM is powered by a +5V external power supply. The TPS65950 power anagement device provides the required CPU core voltages and IO voltages. The EVM can also be powered using an external Lithium Ion/Polymer battery. (Battery not supplied with EVM). RTC is supported through a coin cell.  图2.AM/DM37x评估模块(EVM)外形图 AM/DM37x评估模块(EVM)主要特性: AM/DM37x EVM includes Hardware DM3730 Processor Module 1-GHz ARM Cortex-A8 Processor 800-MHz DSP processor with IVA video accelerators 256MB MDDR/512MB NAND TPS65950 Power Management Module WL1271 Daughter Card: WL1271-based module by LS Research which adds Wireless LAN (IEEE 802.11 b/g/n) and Bluetooth® 2.1+EDR connectivity to the system On board chip antenna 3.7” LCD Touchscreen EVM Base Board Ethernet, SD/MMC, UARTs, USB Host and OTG, Audio and Video Output, JTAG, Keypad, and expansion USB, Serial, and Power cables Universal power supply with regional adapter Stylus and USB SD Card Reader Software AM37x and DM37x Software Development kits provided via included 4GB SD Card Linux Android  图3.AM/DM37x评估模块(EVM)系统框图  图4.AM/DM37x评估模块(EVM)功能框图  图5.AM/DM37x处理器模块电路图(1)  图6.AM/DM37x处理器模块电路图(2)  图7.AM/DM37x处理器模块电路图(3)  图8.AM/DM37x处理器模块电路图(4)  图9.AM/DM37x处理器模块电路图(5)  图10.AM/DM37x电源模块电路图(1)  图11.AM/DM37x电源模块电路图(2)  图12.AM/DM37x电源模块电路图(3)  图13.AM/DM37x评估模块(EVM)主板电路图(1)  图14.AM/DM37x评估模块(EVM)主板电路图(2)  图15.AM/DM37x评估模块(EVM)主板电路图(3)  图16.AM/DM37x评估模块(EVM)主板电路图(4)  图17.AM/DM37x评估模块(EVM)主板电路图(5)  图18.AM/DM37x评估模块(EVM)主板电路图(6)  图19.AM/DM37x评估模块(EVM)主板电路图(7)  图20.AM/DM37x评估模块(EVM)主板电路图(8)  图21.AM/DM37x评估模块(EVM)主板电路图(9)  图22.AM/DM37x评估模块(EVM)主板电路图(10)  图23.AM/DM37x评估模块(EVM)主板电路图(11)  图24.AM/DM37x评估模块(EVM)主板电路图(12)  图25.AM/DM37x评估模块(EVM)主板电路图(13)  图26.AM/DM37x评估模块(EVM)主板电路图(14) 图27.AM/DM37x评估模块(EVM)主板电路图(15)  图28.AM/DM37x评估模块(EVM)主板电路图(16)  图29.AM/DM37x评估模块(EVM)主板电路图(17)  图30.AM/DM37x评估模块(EVM)主板电路图(18)  图31.AM/DM37x评估模块(EVM)主板电路图(19)  图32.AM/DM37x评估模块(EVM)主板元件布局图(顶层)  图33.AM/DM37x评估模块(EVM)主板元件布局图(底层) DM37x处理器模块材料清单见:  DM37x处理器模块材料清单.xlsDM37x电源模块材料清单见: DM37x电源模块材料清单.xlsDM37x EVM主板材料清单见: DM37x EVM主板材料清单.xls详情请见: http://www.ti.com/lit/ds/symlink/dm3730.pdf 和 http://www.mistralsolutions.com/pes-support/support-downloads/amdm37x-evm-documentation-a-software.html |
