    摘要： The present invention provides a method and apparatus for efficiently loading values into scan and non-scan memory elements. First, the network used to distribute control signals to the memory elements is cleared. Second, the desired values are loaded into the scan memory elements. Third, the values from the scan memory elements are propagated to the non-scan memory elements.

    摘要： A suspension for a gyroscopic float assembly in a floating gyroscope system comprises a pair of flexures that each have an outer rim and a plurality of flexure beams extending from the outer rim. A plurality of flexure tabs extend outward from outer perimeter portions of the rims for mounting the flexure assembly to a pair of end caps. A plurality of strain relief passages formed in the rims is arranged to provide relief from thermally induced stresses. A plurality of angular stops formed in inner perimeter portions of the rims is arranged to constrain the flexure against rotation about a selected axis.

    摘要： In a relational database management system (RDBMS), a method of issuing input/output tasks (I/Os) which store record information from a buffer to an after image journal (AIJ) file of a durable disk (the AIJ device) where a group commit size is dynamically adapted to the workload of the AIJ device and to the character and volume of data written to the AIJ file. Record information contains data records (including roll back records) and/or commit records that together form database transactions. A commit record written to the AIJ file indicates that data modifications and/or additions embodied in data records associated with the commit record are durable in the RDBMS in that they are stored in a durable media and are recoverable. Rather than issuing I/Os to the disk based on a fixed timer or a fixed record count, the system writes to the AIJ file based on three workload characteristics: 1) the character of the record information received (data or commit record); 2) the AIJ file throughput, measured based on the buffer contents; and 3) the workload of the I/O device (busy or idle). The present invention avoids making a data dependent server process wait unnecessarily if the AIJ device is not busy, thereby improving response time without overloading the AIJ, and minimizes AIJ I/O in heavy workload situations by making the group commit size as large as possible without idling the AIJ device. The system adapts to a changing workload to provide improved response time and throughput.

    摘要： An addressing method and computer system for sharing a large memory address space using address space within an operating system's virtual address space. The system provides sharing the SSB over many processes without the disadvantages associated with process based global sections. For instance, the novel system does not require that each process maintain its own dedicated page table entries (PTEs) in order to access the SSB thereby requiring less operating system virtual memory to maintain the PTE data structures. The system uses a process to switch to kernel mode, then identifies those sections of the operating system virtual memory space that are not being used; in some cases the unused address space can be 1.5-1.8 gigabytes in size. The unused address space is linked together to form the SSB. The system alters the privileges of the PTEs corresponding to the SSB so that user mode processes can access this usually protected operating system virtual memory space. The result is a statically mapped large memory address buffer (SSB) that can be immediately shared by all processes within the computer system while consuming only a single statically mapped PTE which all processes can use. In one example, 500 processes mapping to a 2 gigabyte SSB requires only 2 megabytes of memory storage for the corresponding PTEs, assuming conventional memory page sizes. In one example, the SSBs are allocated from a system space virtual memory map which is 2 gigabytes in size in a 32-bit VMS operating system.
