General Purpose Digital Data Processor, Systems and Methods

A digital data processor or processing system comprising

• A. one or more nodes that are communicatively coupled to one another, at least one of which nodes a processing module,
• B. one or more memory elements (“physical memory”) communicatively coupled to at least one of the nodes,
• C. at least one of the nodes includes a cache memory that stores at least one of data and instructions any of accessed and expected to be accessed by the respective node,
• D. wherein at least the cache memory stores tags (“extension tags”) specifies a system address and a physical address for each of at least one datum or instruction that is stored in physical memory.

A digital data processor or processing system comprising

• A. one or more nodes that are communicatively coupled to one another, at least one of which nodes a processing module,
• B. one or more memory elements (“physical memory”) communicatively coupled to at least one of the nodes, where one or more of those memory elements includes any of flash memory or other mounted drive,
• C. at least one of the nodes includes a cache memory that stores at least one of data and instructions any of accessed and expected to be accessed by the respective node,
• D. the physical memory and cache memory of the nodes together comprising system memory,
• E. the cache memory of each node storing at least one of data and instructions any of accessed and expected to be accessed by the respective node and, additionally, storing tags specifying addresses for at least one respective datum or instructions in physical memory, wherein at least one of those tags (“extension tag”) a system address and a physical address for each of at least one datum or instruction that is stored in physical memory.
