The system controls the logic of the data acquisition board by programmablelogicdevice (PLD) with the center of the ARM microcontroller and FIFO memory and provides the simulate waveforms.
With the increasing of the prevalence and application in PLD (programmableLogicDevice) nowadays, the main direction of electronic design has been turned into ASIC and FPGA.
随着近年来可编程逻辑器件的大量普及及应用,电子设计的主流方向早已被asic及FPGA等占据。

In the designed encoder, all of the control circuits are realized with a PLD (ProgrammableLogicDevice). The area of the printed circuit board is reduced obviously.
