FPGA in the development of precision instruments

Abstract: Precision is the instrumentation disciplines important part of it is to study the length, thermal, electromagnetic, optical, radio, time and frequency of physical quantities used in instruments and meters, and its development in the important technical indicator that is accurate, and FPGA technology modern digital circuit design as a important means of widely used, its design and development of precision instruments used in the hardware part, to improve the accuracy of precision instrument has important practical significance, so that precision instrument development to a new high-tech platform. FPGA technology in the development of precision instruments of the modern information society the mainstream of development.
     The main purpose of this paper is to study the FPGA in the development of precision instruments. From the subject for parsing, this article mainly divided into three sections. First, to introduce the basic structure FPGA and basic characteristics and the design process, the scope of application and its development trend and set everyone to have a preliminary understanding of FPGA. Secondly, high precision instruments of knowledge, including the concept of precision instruments, precision instruments of development, the emphasis on instruments of the design of the development process. Finally, through FPGA on the high resolution induction logging instrument the application and FPGA in the intelligent measuring appliance the application two examples, has analyzed FPGA thoroughly in the precision instrument development application process.
