Monitoring Device for Monitoring a Circuit

摘要

A monitoring device for monitoring a circuit is provided. The circuit has a main functional unit to perform a main calculation. The monitoring device includes a calculation unit to perform a test calculation in parallel with the performance of the main calculation and to provide a result of the test calculation. The calculation unit is disposed on the circuit. The monitoring device also includes a checking unit to check the result of the test calculation in order to detect a malfunction of the test calculation, and a signal generation unit to generate a signal in response to the result of the check, and to forward the signal to the main functional unit.

1. A monitoring device for monitoring a circuit, wherein the circuit comprises a main functional unit to perform a main calculation, the monitoring device comprising:
a calculation unit configured to:
perform a separate test calculation in parallel with the performance of the main calculation; andprovide a result of the separate test calculation, wherein the calculation unit is disposed on the circuit and is configured as functionally simpler than the main functional unit; a checking unit configured to check the result of the separate test calculation in order to detect a malfunction of the separate test calculation; and a signal generation unit configured to:
generate a signal in response to the result of the check; andforward the signal to the main functional unit.
