Multiprocessing in real-time systems: Part 5

Real-time, multiprocessing systems address the need for increased capacity by distributing among processors the computational loading of the software and the data throughput of the system. Concerns over data flow, synchronization, and control escalate with larger multiprocessing systems. The architecture of these systems must support high performance and wide bandwidth for data flow. The processors must have wide dynamic range and typically must be capable of 32- or 64-bit floating-point math. The software usually has sophisticated, high-level tools for ease of use. Finally, the systems typically adhere to some sort of data bus standards, such as VME, VXI, PCI, or compactPCI.
