US 7,613,592 B2 · Two-channel method for continuously determining at least one output signal from changing input signals

Abstract

There is described a two-channel method for determining at least one output signal from variable input signals sent by a transmitter, using two independent channels and consisting in alternately guiding the input signals to said channels, wherein a multiplexer is used for switching said channels. A microprocessor contained in said channels delivers input test signals transmitted to the channel not currently receiving any variable input signal. Said channel transmits output signals compared with an expected value in order to verify the channel correct operation. Simultaneously, the other channel produces an output signal. Afterwards, the multiplexer switches a control signal.

Dependent claims

A method for continuously determining at least one output signal based on changing input signals, comprising:

providing a chip with a first channel and a second channel, the first channel having a first microprocessor and the second channel having a second microprocessor;
feeding the input signals to the first channel, the input signals being provided by a transmitter;
producing an output signal based on the input signals and taking the output signal from the first channel;
feeding test input signals to the second channel, an expected value being known for a test output signal, the test input signals being generated by the first microprocessor;
determining the test output signal based on the test input signals;
and
comparing the test output signal with the expected value to check whether the second channel is operating correctly.
