    • System and method of a pace engine for governing the different transmission rates tailored for different connections by rate pacing a plurality of queues are described. Roughly described, the pace engine includes a binning controller for receiving queues from a transmit DMA queue manager and determines the earliest allowed time for a particular queue that is stored and paced in a Work Bin, a Fast Bin, or a Slow Bin. A pace table stores information about the minimum inter-packet-gap for each connection that is coupled to the transmit DMA queue manager. A timer is coupled to the binning controller with a multi-bit continuous counter that increments at a predetermined time unit and wraps around after a predetermined amount of time.
    • 描述了用于通过速率起搏多个队列来为不同连接量身定制的不同传输速率的步调引擎的系统和方法。 粗略地描述,速度引擎包括用于从发送DMA队列管理器接收队列的分档控制器,并且确定在工作仓,快速仓或慢速仓中存储和起搏的特定队列的最早允许时间。 步速表存储关于耦合到发送DMA队列管理器的每个连接的最小间隔间隔的信息。 定时器与具有多位连续计数器的分箱控制器耦合,该计数器以预定时间单位递增并在预定时间量之后卷绕。

    • This invention pertains to a process for preparing diacetylenics, to diacetylenic compounds and to reduced diacetylenic compounds. The process includes the steps of reacting coupling an acetylenic acid in presence of cupric chloride in Ethylamine and hydroxylamine hydrochloride to form a diacetylenic diacid; reacting the diacetylenic diacid with a lithium compound, trimethylsilyl chloride and hydrochloric acid to form a diacetylenic compound; and reducing the diacetylenic compound to a reduced diacetylenic compound. The diacetylenic compounds have the formula COOH—(CH2)m—C≡C—C≡C—(CH2)m—C(═O)—R or R—C(═O)—(CH2)m—C≡C—C≡C—(CH2)m—C(═O)—R and the reduced cyclic diacetylenic compounds have the formula COOH—(CH2)m—C≡C—C≡C—(CH2)m—CH2—R or R—CH2—(CH2)m—C≡C—C≡C—(CH2)m—CH2—R, where m is 1-18 and R is selected from alkyl groups of 1-10 and cyclic groups containing 6-35 carbon atoms and aryl moieties
    • 本发明涉及制备二乙炔基化合物,二乙炔化合物和还原二炔化合物的方法。 该方法包括使乙酸氯化物在乙胺和盐酸羟胺存在下偶联乙酸以形成二乙炔二酸的步骤; 使二乙炔二酸与锂化合物,三甲基甲硅烷基氯和盐酸反应,形成二乙炔化合物; 并将二乙炔化合物还原成还原的二乙炔化合物。 二乙炔化合物具有式COOH-(CH2)mC = CC = C-(CH2)mC(= O)-R或RC(= O) - (CH2)mC = CC = C-(CH2)mC(= O )-R并且还原的环状二炔化合物具有式COOH-(CH 2)m C = CC = C-(CH 2)m -CH 2 -R或R-CH 2 - (CH 2)m C = CC = C-(CH 2)m - CH2-R,其中m为1-18,R选自1-10的烷基和含有6-35个碳原子的环状基团和芳基部分
