摘要： A circuit is described for functioning as a transparent latch, a latch where the data is determined by the state of a data signal at the time a signal changes state, a D-type flip-flop, and a scan path element. The mode of operation of the circuit is determined by the condition of respective ones of a set of control signals (CLK, SCLK, LE, SE).

摘要： The present invention provides an expandable ECL matrix shifter which has very few interconnecting wires. The shifter can perform a multicolumn right shift or a multicolumn left shift in one cycle, and it has independent wrap and fill capabilities. Two 2 to 1 multiplexers are provided for each bit position of the input signals. The input signals provide one of the inputs for both of the multiplexers. The second input of each multiplexer is a signal indicating what type of fill is desired. The shifter has horizontal data input lines, vertical data output lines, and diagonal select lines. A bipolar transistor is located at each intersection of a data input line and a data output line. These transistors selectively connect the data input lines to the data output lines in response to signals on the diagonal select lines. Each horizontal data input line is divided into two parts. The division of the data input lines into parts is along a major diagonal of the matrix. The parts of the data input lines on one side of the major diagonal are activated by the output of one of the multiplexers, and the parts of the data input lines on the other side of the major diagonal are activated by the outputs of the second multiplexer.

摘要翻译： 本发明提供一种可扩展的ECL矩阵移位器，其具有非常少的互连线。 移位器可以在一个周期内执行多列右移或多列左移，并具有独立的换行和填充功能。 为输入信号的每个位位置提供两个2到1个多路复用器。 输入信号为两个复用器提供输入之一。 每个多路复用器的第二输入是指示期望什么类型的填充的信号。 移位器具有水平数据输入线，垂直数据输出线和对角线选择线。 双极晶体管位于数据输入线和数据输出线的每个交叉点。 这些晶体管响应于对角选择线上的信号选择性地将数据输入线连接到数据输出线。 每个水平数据输入线分为两部分。 将数据输入线划分成多个部分沿着矩阵的主要对角线。 主对角线一侧的数据输入线的部分由多路复用器之一的输出激活，主对角线另一侧的数据输入线的部分被第二多路复用器的输出激活 。
