基于FPGA的高速A/D转换控制模块的设计

A Design of High-speed A/D Convertion Control Module Based on FPGA

采用FPGA器件EPF 10K 10LC 84-4实现了对高速A/D转换芯片TLC 5540的实时采样控制,并利用片内嵌入式阵列块-EAB作为F IFO缓冲器进行高速采样数据存储,完成数据的缓冲、处理、传输等功能.该模块可广泛应用于通信、打印机、数字电视等设备中.

By using FPGA device EPF10K10LC84-4 as the controller of the A/D converter TLC5540,an A/D convertion control module is accomplished to memorize the data in a FIFO buffer storage made up of the EAB blocks within the FPGA device. This module achieves the functions of amortization, transfer and processing the digitals. It can be widely used in communications and many types of equipment such as printers and digital televisions.
