ABSTRACT:
A method of displaying multi-channel waveforms including the steps of: dividing at least one waveform screen in a video memory which is mapped to a display terminal into a plurality of waveform windows, wherein boundaries of each of the windows are defined by a plurality of values set in at least a set of boundary registers; establishing a waveform parameter table in a system memory; writing waveform data into a logical space in the waveform screen corresponding to a waveform by writing operations from CPU to the video memory; and based on parameters of the waveform windows in the waveform parameter table, performing a display mode defined by the parameter by means of changing the mapping relationship between the video memory and the display terminal, before transmitting the data of each of the waveform windows read out from the video memory to the display terminal.
