Abstract:
1. A waveform data display device comprising: a microprocessor configured to receive collected parameter information and to generate information on a position, a length and a color value with the maximum brightness of each vertical line for drawing a waveform corresponding to the received parameter information; a logic processing apparatus configured to use the generated information on the length and the color value with the maximum brightness of each vertical line to calculate the color values gradually changing along the length of the vertical line at different positions of each vertical line based on a midpoint algorithm using integer operations, and to combine waveform information of the waveform based on a display time sequence, the generated information on the position of each vertical line and the calculated color values gradually changing along the length of the vertical line at different positions of each vertical line; and a display unit for displaying the waveform based on the combined waveform information, wherein the logic processing apparatus comprises a sloping line midpoint processing unit configured to use the information on the length and the color value with the maximum brightness of each vertical line to calculate the color values gradually changing along the length of the vertical line at different positions of each vertical line based on the midpoint algorithm using integer operations, wherein the sloping line midpoint processing unit ( the first comparator ( the output terminals of the first register (
