Abstract
An asymmetric multiprocessor apparatusis provided in which respective slave diagnostic unitsare associated with corresponding execution mechanisms. A master diagnostic unittracks the migration of thread execution between the different execution mechanismsso that the execution of a given thread can be followed by the diagnostic mechanismsand this information provided to the programmer. The execution mechanismscan be diverse such as a general purpose processor, a DMA unit, a coprocessor, an VLIW processor, a digital signal processorand a hardware accelerator. The asymmetric multiprocessor apparatuswill also typically include an asymmetric memory hierarchy such as including two or more of a global memory, a shared memory, a private memoryand a cache memory.
