摘要
针对声波测井采集数据量较大给实时传输造成较大困难的现状,本文提出了一种基于LZW的无损压缩算法的PFGA实现方案。根据声波测井数据采集电路的特点,本文设计了声波测井的LZW硬件压缩系统框图和控制器的控制时序,采用Verilog HDL对核心控制单元进行了模块化描述和详细设计。并在QUARTUSⅡ平台上用EP2C5Q208C8N进行了时序仿真验证,结果表明:该控制器设计是有效的,并具有较好的移植性和可扩展性。
According to the present situation that acoustic logging with large data acquisition brings great difficulties, the paper puts forward the FPGA implementation scheme of lossless compression algorithm based on LZW. According to the characteristics of data acquisition circuit in acoustic logging, it designs the system charLof LZW hardware compression and the controlling sequence of controllers in acoustic logging and makes a modularized description and a detailed design on the core control units with verilog HDL. It also carries out the timing simulation in the platform of QUARTUS II, and the results show the design of the controller is effective and it has good portability and scalability.
