    Abstract: Methods and apparatuses that enable memory devices to inform graphical processing systems about the results of WRITE de-skew training. A WRITE-TRAINING mode is added to a memory device. When the WRITE-TRAINING mode is asserted the memory data mask (DM) pin is converted to an output port. Incoming WRITE data is strobed-into the memory device and the resulting data pattern is compared to a desired pattern. If the incoming WRITE data and strobed-in data match, that result is sent to the graphical processing system by setting the DM pin HIGH. If the incoming WRITE data and the strobed-in data do not match, that result is sent to the graphical processing system by setting the DM pin LOW. Beneficially, the incoming data and the desired pattern are derived from pseudo random bit sequence (PRBS) sources.

    Abstract translation: 使存储器件能够通知图形处理系统有关WRITE去偏移训练结果的方法和装置。 将WRITE-TRAINING模式添加到存储设备中。 当WRITE-TRAINING模式被置位时，存储器数据掩码（DM）引脚被转换为输出端口。 进入的写入数据被选通到存储器件中，并将所得到的数据模式与期望的模式进行比较。 如果输入的WRITE数据和选通数据匹配，则通过将DM引脚设置为高电平将该结果发送到图形处理系统。 如果输入的写入数据和选通数据不匹配，则通过将DM引脚设置为低电平将该结果发送到图形处理系统。 有利地，从伪随机位序列（PRBS）源导出输入数据和期望模式。

    Abstract: A process to produce a purified dimethyl-furan-2,5-dicarboxylate (DMFD) by feeding furan dicarboxylic acid and methanol to an esterification zone to generate a crude diester composition, and purifying the crude diester composition with a physical separation process followed by crystallization, solid liquid separation, and optionally drying to produce a purified DMFD composition. A portion of the stream generated by solid liquid separation can be dissolved and subjected to crystallization and solid liquid separation repeatedly. The process is useful to produce a purified DMFD composition having a low b*, at least 98 wt. % DAFD solids, and a low concentration of 5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) and methyl 5-formylfuran-2-carboxylate (MFFC).

    Abstract: Disclosed is a process to produce a purified vapor comprising dialkyl-furan-2,5-dicarboxylate (DAFD). Furan-2,5-dicarboxylic acid (FDCA) and an alcohol in an esterification zone to generate a crude diester stream containing dialkyl furan dicarboxylate (DAFD), unreacted alcohol, 5-(alkoxycarbonyl)furan-2-carboxylic acid (ACFC), and alkyl furan-2-carboxylate (AFC). The crude diester stream is fed to a flash evaporation zone to produce a vapor alcohol composition and a first liquid DAFD rich composition. At least a portion of the remaining alcohol can be separated from the first liquid DAFD rich composition to produce a second alcohol vapor and a second liquid DAFD rich composition, followed by separating AFC from the second liquid DAFD rich composition to product an AFC vapor and a partially purified DAFD rich composition, followed by separating a portion of the DAFD from the partially purified DAFD rich composition to produce a purified DAFD vapor.
