The design of the logical analysis apparatus of one-chip microcomputer and the EDA's technology baseding on
【Abstract】This design uses the one-chip microcomputer to be controlled gathering of logical signal levels of 8 tunnels, Use CPLD's chip of EDA's technical design to the logic signal processing and Control scanning to the lattice signal and The result of display analysis on the oscillograph , Use the interrupt mode exchange data between one-chip microcomputer and CPLD. this design has 1 and 3 grade of method of activation , trigger word seat display and time to be marked thread display etc. merit ability,As well as friendly operation interface and waveform stabilization what shows etc. characteristic , And widen the oscillograph use merit ability .
