摘要： In the methods and devices of the present disclosure, a dummy compensation word is added to the data packet such that the UDP checksum value need not be modified from any previous value, regardless of changes to the UDP payload. Because the UDP checksum value is not modified in embodiments of the present disclosure, there is no delay waiting for a UDP checksum value to be calculated and no need for additional buffers to store the data packet contents because of UDP checksum calculations. The dummy compensation word is calculated so that the unmodified value maintained in the checksum is the checksum for the data packet including the dummy compensation word. By placing the compensation word in the data packet after the last word in the UDP payload, there is no, or very minimal, processing delay and data packet buffering hardware is significantly reduced.
摘要翻译：在本公开的方法和装置中，将虚拟补偿字添加到数据分组，使得不需要从任何先前的值修改UDP校验和值，而不管对UDP有效载荷的改变。由于在本公开的实施例中UDP校验和值未被修改，所以不需要等待UDP校验和值的延迟，并且由于UDP校验和计算，不需要额外的缓冲器来存储数据分组内容。计算虚拟补偿字，使得维持在校验和中的未修改值是包括虚拟补偿字的数据包的校验和。通过将补偿字放置在UDP有效载荷中的最后一个字之后的数据包中，没有或非常小的处理延迟，并且数据包缓冲硬件显着减少。

摘要： A laser driver for generating drive waveforms that are suitable for driving a single VCSEL or an array of VCSELs. A digital controller is integrated into the laser driver and is utilized to initially program and selectively adjust during the operation of the driver one or more of the following VCSEL drive waveform parameters: (1) bias current, (2) modulation current, (3) negative peaking depth, and (4) negative peaking duration. The laser driver has an aging compensation mechanism for monitoring the age of the laser and for selectively adjusting the dc and ac parameters of the VCSEL drive waveform to compensate for the aging of the laser. The laser driver also has a temperature compensation mechanism for monitoring the temperature of the driver IC and selectively adjusting the dc and ac parameters of the VCSEL drive waveform to compensate for the changes in temperature.
