Abstract: A method and system for automatically maintaining data consistency across two or more hierarchically arranged databases is disclosed. A master list and an environmental variable file are created for use in maintaining the data consistency of a cell view. A cell view in a selected database is then checked to see if it has been modified by performing date-time stamp shadowing. If the cell view is modified, the cell view is then retrieved by derivative lists created from the master list and the environmental variable file and translated based on criteria from the environmental variable file. Verification is then performed on the translated cell view once again based on criteria from the environmental variable file. This verification creates a signature for the translated cell view. Signatures are then checked for being out of date with respect to any dependency listing contained internally. Any signature found to be out of date triggers an automatic re-verification of the pertinent data file.

Abstract: A method and circuitry are provided for latching information. The information is selectively transferred from a selected one of: a first node (DIN) to a second node (416); and a third node (SIN) to a fourth node (419a-b). The transferred information is selectively latched by coupling the second node (416) to the fourth node (419a-b) in response to a signal (308, 410).

Abstract: A processing system and method of operation are provided. At least one execution unit processes information of a register in response to an instruction specifying the register. Each of multiple control units selectively allocates a respective one of multiple buffers to store the information in response to the instruction.
