The multi-core system includes a general purpose CPU executing commands in a CPU programming language and a graphic processing unit (GPU) executing commands in a GPU programming language. A command processor is coupled to the CPU and CPU. The command processor sequences jobs from a program for processing by the CPU or the GPU. The command processor creates commands from the jobs in a state free command format. The command processor generates a sequence of commands for execution by either the CPU or the GPU in the command format. A compiler running a meta language converts program data for the commands into a first format readable by the CPU programming language and a second format readable by the GPU programming language. ## Claims ### Claim 1 A system for executing a program, the system comprising: a first processing unit device configured to execute a first sequence of one or more commands in a first programming language;
