WAVEFRONT PIPELINE DYNAMIC INTERFACE AND ITS OPERATING PROCESS

摘要

FIELD: data processing systems including bus interfaces. SUBSTANCE: interface has delay devices, pre-selected delay period setting circuit, data comparison logic circuit, and pre-selected delay period varying circuit. Interface operates as follows: data signals received from sending end are delayed by means of programmable delay device corresponding to each signal and then recorded by receiving device; programmable delay is set for each delay device during initialization procedure with the result that each signal is aligned against last arriving signal. In addition phase of input-output clock signal controlling data signal recording is controlled so as to ensure that data function transition were disposed practically in center of data confidence window. EFFECT: provision for data alignment on receiving end of interface. 15 cl, 10 dwg
