Accompanying drawing explanation
Fig. 1 is the utility model electrical structure block diagram.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figure 1, the peripheral circuit that the utility model embedded data processing unit comprises processor and is connected with processor, wherein peripheral circuit comprises power module, memory module and Peripheral Interface, power module input DC power, the multiple electric pressures changing into processor need through power supply chip are connected to the working power end of processor; Memory module is connected by data line with processor; Processor main board is provided with various interface, is connected respectively from different Peripheral Interfaces.
In the present embodiment, have circuit in the embedded data processing unit of four core processors and be made up of single circuit board and casing, plate carries TMS320DM8168 and its main peripheral hardware; After 12V power supply enters from power input interface, be converted into 3.3V, 1.8V and 1.0V by DCDC power supply chip.
Based on the embedded data processing unit composition block schematic illustration of four core processors.Four core processor mainboards has kilomega network interface, USB interface, SATA hard disc interface, RS232 interface, RS485 interface and the special interface that tests the speed.
Four core process TMS320DM8168 have an ARM core and a DSP core and two stones, adopt TMS320DM8168 tetra-core processor of TI (Texas Instruments), this processor mainly comprises two processor cores: 1.35GHz ARM Cortex-A8RISC MPU and 1.2GHz C674x DSP; Peripheral circuit adopts 512M NAND FLASH, 2G DDR3, the peripheral circuits such as gigabit network interface; Wherein ARM core mainly completes the management of each peripheral hardware, receives H.264 code stream and the data of automatic network by gigabit network interface, and the H.264 video flowing gimmick realizing automatic network stores.USB port connects the USB port equipment such as mouse, keyboard or USB flash disk; SATA mouth connects hard disk and is used for view data storage; SD card interface is used for inserting SD card, realizes the storage of code stream and picture; RS232 and RS485 interface is used for serial communication and debugging; The triple coil that the interface that tests the speed shows three lanes for the I/O cause for gossip connecting vehicle checker tests the speed.
