Description: 采用TI公司的TMS320C6713，通过地址译码和总线隔离，直接将数字图像传感器芯片OV7620接入；利用EDMA独立传送的特点，在不增加DSP软件开销和对总线占用的情况下，实现视频图像的实时采集和处理。经过验证，系统具有实时性好、成本低、开发周期短的特点。通过总线隔离和数据锁存实现了DSP与低速LCD显示模块的接口。针对具体的硬件电路给出了驱动例程。-Using TI s TMS320C6713, through the address decoder and bus isolation, directly to the digital image sensor chip OV7620 access use EDMA transfer characteristics of an independent, not to increase in the DSP software overhead and bus occupancy, the realization of video images Real-time acquisition and processing. After verification, the system has good real-time, low cost, short development cycle characteristics. Through isolation and data bus latches to achieve a low-speed DSP with LCD display module interface. Hardware-specific driver routines given circuit. Platform: |
