现场可编程器件的异步串行配置

Asynchronous Configuration of FPGA

介绍了可编程集成电路的基本知识，着重介绍了大规模现场可编程集成电路ＦＰＧＡ的编程方案，以Ａｌｔｅｒａ公司的ＦＬＥＸ８０００系列芯片为例，给出了使用单片机和微机的两种配置实例。

Field programmable gate array (FPGA) is a new kind of programmable logic device(PLD) used to implement custom logic functions. FPGA can implement any Boolean expression or registered function with built in logic structures. In contrast, off the shelf ICs, such as TTL devices, provide a specific logic function and cannot be modified to meet design requirements of individual circuit. This paper provides the basic knowledge of programmable logic device, gives more information about FPGA and the solution of the configuration of FPGA, illuminates the process of the configuration of FPGA, enumerates two representative configuration examples by using a single chip computer and a microcomputer.
