Abstract:
A method for executing multiple computational primitives is provided in accordance with exemplary embodiments. A first computational unit and at least a second computational unit cooperate to execute multiple computational primitives. The first computational unit independently computes other computational primitives. By virtue of arbitration for shared source operand buses or shared result buses, availability of the first and second computational units needed to execute cooperatively the multiple computational primitives is assured by a process of reservation as used for a computational primitive executed on a dedicated computational unit.
