Abstract: Short traces of consecutive CPU references to storage are accumulated and processed to ascertain hi. ratio as a function of cache size. From this determination, an allocation of cache can be made. Because this determination requires minimal processing time, LRU-referenceable memory space among concurrently executing sequential processes is used dynamically by CPU cache manager.

Abstract: A METHOD FOR ACCESSING DATA FROM A SELF-SERVICE POINT-OF-SALE TERMINAL of the Invention A new use of relational database management at a host CPU interacting with selection requests from remote POS terminals is described. The new use includes (1) dynamic database generation of textual screens from the CPU relational data manager together with information for accessing a video picture source local to the POS terminal for generating selected picture screens, and (2) the textual searching of a virtual menu tree (part of a text screen) whose starting node is dependent upon the user's choice of picture or text information. The changed content of the text and picture screens is solely a function of the relationally accessed data designated by the user's menu selection.
