Method of layering cache and architectural specific functions to promote operation symmetry |
摘要 |
Cache and architectural functions within a cache controller are layered so that architectural operations may be symmetrically treated regardless of whether initiated by a local processor or by a horizontal processor. The same cache controller logic which handles architectural operations initiated by a horizontal device also handles architectural operations initiated by a local processor. Architectural operations initiated by a local processor are passed to the system bus and self-snooped by the controller. If necessary, the architectural controller changes the operation protocol to conform to the system bus architecture.
