NDLI: Design considerations for a heterogeneous tightly-coupled multiprocessor system

Abstract	In a multiprocessor system, processors share main memory and a single copy of the operating system in shared main memory controls the entire system. Basically each processor can execute, any of the programs in the system. (This type of multiprocessor system is sometimes called a tightly-coupled multiprocessor system to distinguish from another type of multiprocessor system in which each processor has its own main memory and operating system. In this paper a "multiprocessor system" means a "tightly-coupled multiprocessor system" unless otherwise noted.) A multiprocessor system usually consists of identical processors, which have same computing speeds as well as the same functional characteristics. In this paper a more general type of multiprocessor system which consists of processors of different computing speeds are discussed. The component processors are equivalent in the hardware functions but have different performance characteristics. This type of multiprocessor system, a heterogeneous multiprocessor system, has the following merits as compared with a homogeneous multiprocessor.
