A system where a frontend CPU deals with all I/O and system tasks and the others do the number crunching. Contrast NUMA and SymmetricMultiProcessing.

Most modern computers use AsymmetricMultiProcessing, with processors to handle graphics, network or disk access logic. These processors may have special operations to achieve these tasks or may be generic processors tasked with the function. This seperation of function removes constriants from the CPU (or CPUs) to run the application logic with fewer scheduling and "house keeping" operations to run. --StuartYeates

This does not fall under AsymmetricMultiProcessing. These other chips are coprocessors at best, or as little as DSPs. If you count this as AMP, then even the board chipset would count as CPUs, which is obviously absurd. --AristotlePagaltzis
