Abstract
A processor, including a core; and a cache-coherent memory fabric coupled to the core and having a primary cache agent (PCA) configured to provide a primary access path; and a secondary cache agent (SCA) configured to provide a secondary access path that is redundant to the primary access path, wherein the PCA has a coherency controller configured to maintain data in the secondary access path coherent with data in the main access path.
Claims25
A processor, comprising:
- a core;
- and
- a cache-coherent memory fabric coupled to the core and having:
- a primary cache agent (PCA) configured to provide a primary access path;
- and
- a secondary cache agent (SCA) configured to provide a secondary access path that is redundant to the primary access path,
- wherein the PCA has a coherency controller configured to maintain data in the secondary access path coherent with data in the main access path.
4 more elements
A method of processing, comprising:
- providing, by a primary cache agent (PCA), a primary access path;
- providing, by a secondary cache agent (SCA), a secondary access path that is redundant to the primary access path;
- and
- maintaining, by a coherency controller of the PCA, data in the secondary access path coherent with data in the main access path.
1 more element
A processor, comprising:
- a core;
- and
- a cache-coherent memory fabric coupled to the core and having:
- a primary cache agent (PCA) means for providing a primary access path;
- and
- a secondary cache agent (SCA) means for providing a secondary access path that is redundant to the primary access path,
- wherein the PCA means has a coherency controlling means for maintaining data in the secondary access path coherent with data in the main access path.
