CPLD在水下冲击波记录仪中的应用

Application of CPLD in recorder of underwater shock wave

XCR3256是Xilinx公司推出的CoolRunner系列CPLD器件,在数字系统设计中的应用非常广泛。本文详细分析了Cool-Runner系列CPLD的特点、结构及功能,使用VHDL语言编程实现数字逻辑,实现了水下冲击波记录仪电路的数字电路部分。由于采用该器件,简化了电路设计,减小了设备体积,同时也使设备的可靠性和设计的灵活性大大提高。

XCR3256 is used in the design of digital system widely, and it is a CoolRunner series CPLD which are produced by Xilinx corporation. In this paper, the characterizations, architectures and functions of CoolRunner series CPLD are introduced. Then, the digital unit of recorder of underwater shock wave is realized with CPLD, which digital logic is programmed with VHDL language. Finally, the circuit design is simplified and the equipment size is downsized. Additionally the equipment reliability and design flexibility are improved greatly.
