ABSTRACT:
A system includes a first processor coupled to a second processor. The first and second processors are coupled to memory. The first processor fetches and executes supported instructions until an unsupported instruction is detected. The second processor executes the unsupported instruction. If there are less than a threshold number of consecutive supported instructions before the next unsupported instruction, the second processor loads the instructions in the first processor for execution so that the first processor does not fetch the instructions. If there are more than a threshold number of consecutive supported instructions before the next unsupported instruction, the first processor fetches and executes those instructions.
