特徴とするバスモニタ装置。[Claim for Utility Model Registration] A bus monitor device that monitors signals on a system bus of a computer system includes a RAM for temporarily storing signals on the system bus sampled in bus clock units, and a RAM for temporarily storing signals on the system bus that are sampled in bus clock units. The main body of the bus monitor device, which has a control circuit and a control circuit configured on one board, is connected to the system bus, and the above signals are sequentially and cyclically sent in the order of the bus clock, in the order of the addresses of the RAM, and from the last address to the first address. R
AM, and if a trigger condition occurs, the storage of subsequent signals will be stopped, and the above RAM will be stored by then.
A bus monitor device that edits signal states on a system bus stored in a computer system by an SVP (service processor) attached to the computer system and displays the edited signals on a CRT.
