Abstract
Control signals of an I/O or peripheral bus are sensed during cycles of the bus and information describing bus phases of the signals is derived by sensing the control signals and is stored in a register. During a sampling time period, a processor reads the bus phase information from the register and computes bus activity information by using the bus phase information. The computed bus information is continuously updated and displayed to reflect actual communication activity on the bus occurring substantially in real-time.
