用VHDL语言在FPGA上实现了8路温度数据的采样功能。控制THS1408芯片进行AD转换，采样后存入对应的8组寄存器，并产生使能信号通知其他模块进行8路数据的统一采样。-8-channel temperature data sampling function is implemented on FPGA using VHDL language. Control THS1408 chip AD converter, and sampled into the corresponding set of registers, and generate the enable signal to inform other modules for a uniform sampling of the 8-way data.
