Abstract: A system monitors unaligned memory accesses by a processor of a computer system. The processor automatically generates a fault when attempting an unaligned memory access. Unaligned memory access faults are disabled in response to a fault generated by a first faulting instruction. The first faulting instruction is executed. A trap is generated by executing the first faulting instruction. Unaligned memory access faults are enabled in response to the trap.

Abstract: The present invention generally relates to an apparatus and method for efficiently translating virtual addresses utilizing either single address space or multiple address space models in a virtual memory management system. In particular, a Virtual Hash Page Table (VHPT), an extension of the Translation Lookaside Buffer (TLB) hierarchy, is designed to enhance virtual address translation performance. Virtual Hash Page Table (VHPT) efficiently supports two different methods of operating systems use to translate virtual addresses to physical addresses. This directly benefits the highly frequented path of address resolution.

Abstract: A system for rapidly and easily searching large collections of documents using standard web browser programs as the user interface. The present invention parses a collection of text documents to identify symbols therein and builds a database file which identifies the file and line locations of each symbol identified. The database file is constructed to permit rapid searching for symbols to permit interactive use of the present invention as a search tool. A database client process interacts with the web browser via standard CGI techniques to convert browser commands and queries into appropriate server process requests. A server process receives such requests and manipulates the database files in response to the requests. Query results returned to the client process are then reformatted by the client process to return a document with hypertext links in place of search keys located in the database (e.g., an HTML page).
