Abstract: An embodiment of the present invention is a technique for recording relevant information in a graphical user interface (GUI) window. Relevant information on an analysis window is saved in a summary report array using one of an automatic recording mode and a selective recording mode. The analysis window is part of the GUI to analyze state information from a panel dump file retrieved from a computer system. The saved relevant information is displayed on a report window.

Abstract: An embodiment of the present invention is a technique to provide a graphical user interface (GUI) to analyze memory operations in a computer system. A job summary window shows state information of jobs in at least a unit panel. The unit panel represents at least a functional unit in the computer system. A memory job window shows state information of memory jobs in a functional unit selected from the unit panel to provide diagnostic information to the user. The state information being obtained from a panel dump file retrieved from the computer system.

Abstract: An embodiment of the present invention is a technique for providing a graphical user interface (GUI) to view system state of a computer system. An error window displays an error condition of a failed unit in a plurality of functional units in a computer system based on a panel dump file. A warning window shows a warning condition that potentially causes a problem in analyzing system state of the computer system or the error condition.

Abstract: An enhanced computer system architecture provides a processor supported by a general cache and a mini-cache wherein the mini-cache will supply requested data words not available in the general cache thus eliminating the extra clock periods necessary to access main memory. The mini-cache stores frequently used data words and is refilled concurrently during processor command execution and is settable for handling data words or code words or both. A data queue storage stores a block of words which duplicate words in main memory. If the requested address matches an address register block in the mini-cache, the data queue store will make the words in the data queue available to requests from the processor. The mini-cache also monitors the system bus for any "write" operations which might change the validity of the data in the address register block of the mini-cache. In this case, the data stored in the mini-cache is invalidated and cannot be used by the processor.
