High-speed sampling and filtering controller based on FSM

针对单片机采样控制的速度局限,利用有限状态机的方法,设计了基于FSM和FPGA的高速采样滤波控制器,完成了对两路高速A/D转化器TLC5510和高速自适应滤波器的控制,并进行了时序仿真,给出了高速自适应滤波系统的结构框图。结果表明:基于有限状态机和FPGA的设计方法是完成高速器件控制的有效方式。

Aiming at the speed limits in sampling with single chip microcomputer, a new High - speed sampiing and filtering controUer based on definite state machine and FPGA was designed. It could control two high - speed A/D converters, namely TLC5510, and one high - speed adaptive filter. At last, the sketch map of the high - speed adaptive filtering system was given. It indicates that it＇s an effective way to control the high - speed devices based on definite state machine and FPGA.
