HIGH SPEED PIPELINE DEVICE AND METHOD FOR GENERATING CONTROL SIGNAL OF THE DEVICE

摘要

PURPOSE: A pipeline device and a method for generating a controlling signal of the device are provided to make high speed an output point of the first data by minimizing the margin with multi phase clock signals. CONSTITUTION: The pipeline device includes n data passing portions, n pipe registers and a control signal generating portion. The n data passing portions have at least one or more each other different transmission time(T1,T2,...Tn≤P : P is one period of a reference clock signal) and is subordinately connected between an input terminal and an output terminal. The n pipe registers are disposed to the input terminal of each of the data passing portions and is to latch the passed data from the fore-end. The control signal generating portion subordinately generates n-1 pipeline controlling signals with a method generating the nth pipeline controlling signal of the n pipeline registers in response to the reference clock signal and generating a pipeline controlling signal of the n-1th pipeline register in response to the nth pipeline controlling signal and then supplies the generated n pipeline controlling signals to the n pipeline registers respectively.
