In order to solve the problem high-performance real-time, high-speed the image data storage generated by the detector. In this thesis, it choose an suitable portable image storage hard disk of SATA interface, it is relative to the existing storage media. It has a large capacity, high transfer rate, inexpensive, power-down data which is not lost, and many other advantages. This paper focuses on the link layer of the protocol, analysis the implementation process of SATA2.0 protocol, and build state machines. Then analyzes the characteristics resources of Kintex-7 FPGA family, builds state machines according to the agreement, write Verilog implement link layer modules, and run the simulation test. Finally, the test is on the Kintex-7 development board platform. It meets the requirements SATA2.0 protocol basically.
In order to alarm the fire and analyze the material burned, the high efficiency imaging system is designed to monitor the fire. The system selects the high performance CMOS image sensor, utilizing real-time DSP with higher computing power, it is designed based on DSP C6748 by IIC serial port flame detectors video camera’s registers, and the generated image data sent to DSP by VPIF interface, the image algorithm is transplanted to DSP, at last, the system will alarm the fire and output spectral characteristics of the burning material via Ethernet interface. This system completes algorithm hardware realization, and the algorithm can detect image in real-time and extract the effect of spectral characteristics of burning material, so that the algorithm processing can speed up from minute level on the PC to the sub-second level.
