Apparatus and method for monitoring signals transmitted in bus

Abstract

A signal monitor includes a signal collecting unit, a register, a processing unit, and a Reduced Media Independent Interface (RMII). The signal collecting unit collects real-time signals from a bus, converts the real-time signals into accessible data, and stores the accessible data in the register. The processing unit retrieves the accessible data from the register and determines status of the real-time signals by examining the accessible data. The RMII converts the status of the real-time signals into Ethernet frame packets and transmits the Ethernet frame packets to a control terminal via an Ethernet interface. A method for monitoring signals transmitted in a bus is also provided.
