Defect repair for a reconfigurable data processor for homogeneous subarrays

A device architecture includes a spatially reconfigurable array of processors, such as configurable units of a CGRA, having spare homogenous subarrays, and a parameter store on the device which stores parameters that tag one or more elements as unusable. Configuration data is distributed using a sta...

Zusammenfassung:A device architecture includes a spatially reconfigurable array of processors, such as configurable units of a CGRA, having spare homogenous subarrays, and a parameter store on the device which stores parameters that tag one or more elements as unusable. Configuration data is distributed using a statically reconfigurable bus system, to implement the pattern of placement of configuration data, in dependence on the tagged elements. As a result, a spatially reconfigurable array having unusable elements can be repaired.
