System and method for dynamically moving checksums to different memory locations

A system for dynamically moving checksums, comprising:

• means for storing data values, said storing means including a plurality of memory locations;
• means for indicating a location of a checksum for each of said plurality of memory locations;
• means for executing instructions and for accessing said memory locations in response to execution of said instructions;
• and
• means for dynamically moving said checksum from a checksum source location to a checksum destination location, said checksum associated with at least one of said data values stored in said storing means, said moving means configured to update said indicating means to identify said checksum destination location and to update said moved checksum with a data value retrieved from said checksum source location after said checksum has been moved from said checksum source location to said checksum destination location.

A method for moving checksums, comprising the steps of:

• storing a checksum in a first memory location;
• identifying said first memory location via a checksum indicator;
• moving said checksum from said first memory location to a second memory location;
• updating said checksum indicator to identify said second memory location;
• retrieving a value from said first memory location after said checksum has been moved from said first memory location to said second memory location and after said checksum indicator has been updated to identify said second memory location;
• and
• updating said second memory location with said retrieved value.

A method for dynamically moving checksums, comprising the steps of:

• maintaining a checksum in a first memory location, said checksum correlated with each of a plurality of memory locations;
• identifying said first memory location via a plurality of checksum indicators;
• storing a first plurality of data values in said plurality of memory locations;
• updating said checksum with each of said first plurality of data values based on said checksum indicators;
• moving said checksum from said first memory location to a second memory location;
• updating said checksum indicators such that each of said checksum indicators identifies said second memory location;
• during said updating said checksum indicators step, storing a second plurality of data values in said plurality of memory locations and, for each of said second plurality of data values, updating, said moved checksum or a value in said first memory location depending on which of said checksum indicators have been updated by said updating said checksum indicators step;
• and
• updating said moved checksum with said value in said first memory location.

A system for moving checksums, comprising:

• memory having a checksum source location, checksum destination location, and a plurality of memory locations, said checksum source location storing a checksum;
• checksum indicators identifying said checksum source location;
• and
• logic configured to move said checksum to said checksum destination location and to update said checksum indicators such that each of said checksum indicators identifies said checksum destination location, said logic configured to update said checksum source and destination locations based on values stored to said plurality of memory locations while updating said checksum indicators such that neither the checksum source location nor the checksum destination location is storing a complete checksum representation for each of said plurality of memory locations, said logic further configured to update said checksum destination location with a value retrieved from said checksum source location after each of said checksum indicators has been updated by said logic to identify said checksum destination location thereby forming, in said checksum destination location, a complete checksum representation for each of said plurality of memory locations.
