MDBM (Multidomain-based multiprocessing) is a taxonomy category that encompasses applications that span multiple software domains, such as cell phones, automobiles, and many consumer products. This type of multiprocessing has been the bread and butter of embedded-multicore designs for decades. The multiprocessing implementation in many MDBM applications is less about meeting high-end processing performance – rather it is more about: partitioning design, build, and test complexity into semi-independent and manageable chunks; providing more independence in the time domain for resources that would otherwise be in complex contention in a shared capacity such as in a single processor implementation; and providing an optimized processing platform for each type of task that needs to be performed, such as using a microcontroller, DSP, and general-purpose microprocessor in the same system.
