This paper gives a high-speed data buffer interface circuit based on field programmable gate array ( FPGA). Under the control of this circuit unit, the data can be reliably transformed from outer instrument to hi-speed serial color display. 提出了一种以FPGA为控制核心的高速数据缓冲接口电路,在其控制下低速外设输入的数据能可靠地与高速串行彩色显示器进行数据传输。
Combine with the direct digital synthesizer ( DDS) technology, use field programmable gate array ( FPGA) chip as control unit, directly generate the sine pulse width modulation ( SPWM). 本文主要描述利用FPGA现场可编程门阵列器件作为控制核心,结合DDS数字频率合成技术直接形成SPWM脉宽调制波。
