Abstract
In present paper, a DSP-based image capturing and transmitting system is described. As a shortage of peripherals on DSP, external image capturing and data transmitting components are needed in this case. A CMOS image sensor was used to capture images, and an Ethernet MAC controller with PHY was used to transmit image data. In addition, a CPLD was used as the co-controller for timing control. ARP, IP and UDP were functioning during data transmitting through Ethernet. The Driving Mechanism of two main chips and implementing of the protocols were described in detail. Images displayed on the PC show that the system provids good performance. The system is low-cost, simple and low-power.
