Abstract: In order to improve the efficiency of the instrument and help the instrument operator to analyze the
data accurately, the module uses the FPGA ( Field Programmable Gate Array), the 1553B Bus and PCI
( Peripheral Component Interconnect) Bus to complete the module design. This paper first analyzes the
application of 1553B bus in LWD(Logging While Drilling) instrument, completes the design of the module
hardware and the preparation of application software, and completes the modular design of FPGA with the Verilog
HDL( Hardware Description Language). The communication module is used to realize the communication
between the LWD instrument and the host computer. The communication module and the corresponding
application program can be used together to help the operator to make an intuitive judgment on the condition or
the problems of the LWD instrument.
