Data-Flow Architecture

Article Abstract:

Research is being conducted around the world in data-flow computers that would operate at extremely high speeds because of their parallel architecture. Parallel computer architectures can be classified as control-flow, reduction or demand-driven, and data- flow machines, with the last most evenly dividing work between the processors. The data-flow program is a graph showing where the data go and the operations performed when they get there. Data-flow hardware must minimize bottlenecks and idleness and also minimize the connecting processor communication network. A machine being developed at the Massachusetts Institute of Technology uses all- identical, multi-function processing elements. A similar machine at the University of Manchester uses processing elements that are structured as rings. Types of programming languages being developed for data-flow machines are graphical, single assignment, and functional. Critics of data-flow designs say they have trouble dealing with large arrays, have high computational overhead, and perform poorly on classes of some nonparallel problems. Some researchers are attempting to create hybrid machines by combining other architectures. Diagrams illustrate several data-flow architectures, and a graph shows data flow improvement versus a number of processors.

Electro '84: Memories and More

Article Abstract:

Electro '84 will combine with the IEEE centennial anniversary and the Mini-Micro Northeast Conference in Boston on May 15-17, 1984. Most of the sessions at Electro '84 will focus on new developments in electronic components. Several sessions will focus on engineering products to help simplify the engineer's job. A table specifies convention information and schedules.
