APPARATUS AND METHOD FOR MONITORING SIGNALS TRANSMITTED IN BUS

摘要

A signal monitor includes a signal collecting unit, two registers, a processing unit, and a Universal Asynchronous Receiver/Transmitter (UART). 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 two registers. The processing unit reads the accessible data from the two registers and determines status of the real-time signals by examining the accessible data in the reading. The UART asynchronously transmits the status of the real-time signals to a control terminal. A method for monitoring signals transmitted in a bus is also provided.

1. A signal monitor, comprising:
a signal collecting unit adapted to collect real-time signals from a bus, to convert the real-time signals into accessible data; a first register and a second register adapted to store the accessible data; a processing unit adapted to retrieve the accessible data from the first register and the second register, to determine status of the real-time signals by examining the accessible data; and a Universal Asynchronous Receiver/Transmitter (UART) adapted to asynchronously transmit the status of the real-time signals to a control terminal.
