Abstract
Methods and apparatus provide for disabling at least some data path processing circuits of a SIMD processing pipeline, in which the processing circuits are organized into a matrix of slices and stages, in response to one or more enable flags during a given cycle.
Claims32
An apparatus, comprising a SIMD processing pipeline having a plurality of data path processing circuits organized into a matrix of slices and stages, wherein at least some of the processing circuits are operable to at least partially disable operation in response to one or more enable flags during a given cycle.
A method, comprising:
- disabling at least some data path processing circuits of a SIMD processing pipeline, in which the processing circuits are organized into a matrix of slices and stages, in response to one or more enable flags during a given cycle.
A storage medium containing an executable program, the executable program being operable to cause a processing system to execute actions including:
- disabling at least some data path processing circuits of a SIMD processing pipeline of the processing system, in which the processing circuits are organized into a matrix of slices and stages, in response to one or more enable flags during a given cycle.
An apparatus, comprising:
- a SIMD processing pipeline having a plurality of data path processing circuits organized into a matrix of slices and stages;
- and
- a forwarding circuit operable to enable or disable the forwarding of results from the processing circuits to the one or more source operands to the pipeline in response to one or more enable flags during a given cycle.
