Abstract: A signal selection system has input thereto a plurality of redundant input signals (A, B, C, D) having varying values along with signals indicative of the validity of the plurality of input signals, comparison logic (42-52) compares all possible pairwise combinations of the input signals to determine which input signal in each of the input signal pairs has the greater value or to determine if the input signals in each pair have equal values. Selection logic (80) determines which one or more of the values of the input signals from the plurality of valid input signals are to be used to determine the output signal according to a predetermined criterion. The selection logic (80) has a plurality of combinational logic elements arranged to execute predetermined Boolean logic equations in determining which one or more of the values of the input signals from the plurality of valid inputs are to be used to determine the output signal (MID) according to the predetermined selection criterion.

Abstract: A state machine has specific states to boot a microprocessor and retrieve data from the microprocessor's memories while the microprocessor is running, but with operation temporarily suspended under control of the state machine. The state machine is programmed after it is installed on a circuit board with the microprocessor. The state machine is connected to a standard bus and through its specific states provides an interface to the microprocessor as well as the instructions for booting the microprocessor when the microprocessor is powered up.
