MICROPROCESSOR WITH AUTOMATIC SELECTION OF SIMD PARALLELISM.

摘要

A method for controlling the parallelism of operations in a parallel data processor, comprising: monitoring one or more conditions in relation to the processing performed by the parallel data processor; when the one or more monitored conditions correspond to a first state, execute one or more instructions in parallel in two parallel processing elements of the parallel data processor, providing a data path with a first width: and when the one or more monitored conditions correspond to a second state, execute one or more instructions in parallel in the first of the two parallel processing elements, so that the data of a second bandwidth less than the first is processed, while the second of the two parallel processing elements is inactive; in which the monitoring comprises: monitoring the temperature of the data processor in parallel, in which the first state is associated with a temperature monitored at, or below, a temperature threshold and the second state is associated with a temperature by above the threshold; and monitor a task carried out by executing the one or more instructions, in which in the first state the task requests the processing of data of the first width at a frequency greater than a set frequency threshold.
