现场可编程门阵列(FPGA)的主要应用在包括数字信号处理,软件定义无线电,专用电路原型化,医学成像,计算机视觉,语音识别,密码加密,生物信息学,计算机硬件仿真,射电天文学、金属检测和一系列其他的领域。直接数字频率合成器(DDS)是一种用于创建任意波形的频率合成器,它具有固定频率的参考时钟。DDS具有锁相环(PLL)的许多优点,包括更好的频率捷变性,提升信噪比,在切换输出相位的精确控制。脉冲宽度调制(PWM),或脉宽调制(PDM),是一种用于编码信息到脉冲信号的技术。这种技术不仅可以用来编码信息传输,还可以作为电力设备的操作端,特别如惯性载荷设备如电动机。
Field Programmable Gate Arrays (FPGAs) are used in a variety of applications including digital signal processing, software defined radios, prototyping of specialized circuits, medical imaging, computer vision, speech recognition, cryptography, bioinformatics, computer hardware simulation, radio astronomy, Detection and a series of other areas. The Direct Digital Synthesis (DDS) is a frequency synthesizer used to create arbitrary waveforms with a fixed frequency reference clock. DDS has many advantages of phase-locked loops (PLLs), including better frequency agility, improved signal-to-noise ratio, and precise control of switching the output phase. Pulse width modulation (PWM), or pulse width modulation (PDM), is a technique used to encode information into a pulsed signal. This technology not only can be used to encode information transmission, but also can be used as the operating end of electrical equipment, especially such as inertial load equipment such as motors.
