  • System and method for scheduling data transfers among a plurality of data processing units to avoid conflicting data requests
    Patent number: 5070453
    Abstract: A method for allocating resource use to a process having a plurality of tasks in which a set of signals identifying the interferences in resource use among the plurality of tasks is generated and a signal representing an initial non-interfering allocation is produced. The allocation signal is iteratively improved by 1) determining the correlations among the identified interferences, 2) comparing the determined correlations to prescribed criteria, 3) modifying the allocation signal in accordance with the determined correlations, and 4) reforming the interference signal set responsive to the determined correlations. When the determined correlations meet the prescribed criteria in the correlation determination, the corresponding allocation signal is selected as the optimum non-interfering allocation.
