9.5   ALTERNATIVE PARALLEL PROCESSING APPROACHES

Entire books have been devoted to particular alternative and advanced architectures. Although we cannot discuss all of them in this brief section, we can introduce you to a few of the more notable systems that diverge from the traditional von Neumann architecture. These systems implement new ways of thinking about computers and computation. They include dataflow computing, neural networks, and systolic processing.

9.5.1   Dataflow Computing

von Neumann machines exhibit sequential control flow. A program counter determines the next instruction to execute. Data and instructions are segregated. The only way in which data may alter the execution sequence is if the value in the program counter ...
