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.
