A configuration request comprising a security option selected for a particular data stream is received. So inputs of jk flip flop are connected to the inverted q q. This is similar to an up counter but is should decrease its count. The direction of counting is determined by which count input is pulsed while the other count. Like all sequential circuits, a finitestate machine determines its outputs and its next state from its current inputs and current state. The ls160a161a162a163a are highspeed 4bit synchronous counters. Us20140006883a1 system and method for aligning data bits. Synchronous parallel counters synchronous parallel counters.
Systems and methods are disclosed for aligning multiple data bits by adjusting the timing of input lines for those data bits. The least significant four bytes of this counter would be zero, which would place the roll counter at the same point on the table it would be if it had a count of zero.
