用HDPLD实现多bit任意编码波形发生器

Generator of the program controlled multibit code waveform based on HDPLD

文中给出了一种新型的用高密度可编程逻辑器件 (HDPLD)实现的程控编码波形的研究方案与设计步骤 .系统中巧妙地运用一种控制计数器和便于扩展的PS移位寄存器阵列 ,通过微机或单片机控制 ,可形成多位的任意一种组合的编码脉冲波形 .样机测试结果表明 ,实现了编码脉冲重复周期任意可变 ,编码脉冲码元宽度任意可变 ,编码脉冲个数任意可变 .

This paper makes a study of the program controlled waveform coding based on HDPLD . The HDPLD we have used ingeniously in the scheme employs the controlling counters and PS shift register arrays. By means of the control by the on chip computer, a coded pulse wave with infinite combination of 0～255 bits or even more than 255 bits can be formed at will.
