A method for initializing processor cores in a multiprocessor system. The method includes a microcontroller initializing a first processor utilizing a common initialization image for all processor cores within the first processor. The first processor detects and executes system firmware. All remaining processors are initialized utilizing the common initialization image. The executing firmware detects a system configuration of the multiprocessor system. A customized processor initialization image for each of the processor cores in the multiprocessor system is generated and stored to a storage device. The processor cores are triggered to enter a power save state in which all initialization settings of the processor cores are lost. In response to all the processor cores entering the power save state, the first processor core of the first processor is re-initialized using a first customized initialization image generated for the first processor core.

A system and a method for simulation using multiple programming languages is provided. The method can include receiving an annotated source having a first plurality of instructions written in a first programming language and receiving an annotation having a second plurality of instructions written in a second programming language and associated with an annotated instruction from the first plurality of instructions. The method can include extracting the second plurality of instructions to create a routine from the annotation. The method can include building a shared library that contains the routine. The method can include building an application object file by assigning an address to each instruction of the first plurality instructions. The method can include creating an annotation table that contains an address for the annotated instruction and an associated symbol.
