ABSTRACT POWER-UP AND INITIALIZATION OF A MULTIPROCESSOR SYSTEM Initialization of a multiprocessor system with only one nonvolatile memory element is disclosed. The multi- processor system is made up of a nonvolatile memory for storing a boot program, a master main program and a sub- system main program. Several subprocessors, where each subprocessor is made of: 1) A local processing unit that executes the boot program and the subsystem main program; 2) A local memory that stores the subsystem main program; 3) A dual port memory that has a first and a second port the local processing unit is connected to the second port of the dual port memory; and 4) A local selector that selects whether the local processor unit retrieves pro- gram code from the local memory or the dual port memory. When the local processing unit is executing the boot pro- gram, the local select selects the second port of the dual port memory, in the alternative, when the local processing unit is executing the subsystem main program, the local select selects the local memory. Finally, a master processor is connected to the first port of all of the dual port memories and to the nonvolatile memory. The master processor, under control of the master main pro- gram, transfers the boot program and the subsystem main program to the first port of the dual port memory. Also the master processor controls all the local selectors.
