摘要： Some embodiments of the present invention provide a system that schedules read operations for disk drives in a set of disk drives. During operation, the system monitors a write rate for write operations to a given disk drive in the set of disk drives, wherein vibrations generated by the read operations directed to disk drives in the set of disk drives are transmitted to the given disk drive. Then, the read operations for disk drives in the set of disk drives are scheduled based on the write rate for the given disk drive, thereby limiting interference between the write operations and the vibrations generated by the read operations.

摘要： One embodiment of the present invention provides a system that prevents loops from occurring when spanning tree configuration messages are lost while executing a spanning tree protocol on bridges in a network. During operation, the system executes the spanning tree protocol on a bridge. This spanning tree protocol configures each port coupled to the bridge into either a forwarding state, in which messages are forwarded to and from the port, or a backup state, in which messages are not forwarded to or from the port. The system also monitors ports coupled to the bridge to determine when messages are lost by the ports. If one or more messages are lost on a port, the system refrains from forwarding messages to or from the port until no messages are lost by the port for an amount of time.

摘要： A system that characterizes degradation of a component in a system. During operation, the system monitors inferential variables associated with a specimen of the component. Next, the system determines a time for the onset of degradation for the specimen and determines a time for the completion of degradation for the specimen. The system then computes a time interval between the onset of degradation and the completion of degradation, and uses the time interval to look up an entry in a defect library to obtain information which characterizes the degradation of the specimen of the component.

摘要： The invention is directed to a method and apparatus for simulating a digital logic circuit simulator. In particular, a block object, representing a component of the digital logic circuit, is instantiated. An event object having a queue is also instantiated. The queue holds an ordered list of destinations, which are representative of the block objects that the event object initiates an action with. When the event object interacts with the block object, this initiates behavior in the block object indicative of behavior of the component in the digital system. The digital logic circuit simulator components, namely the block object and the event object, can be instantiated in a run-time object oriented language, such as the JAVAnull language promulgated by Sun Microsystems. The block object can initiate a dynamic addition to the destination queue. Additionally the destination can be another event object. When the destination is another event object, another event object is initiated. The new event object may be dynamically created within the instructions of adding to the destination queue, and may based upon test for the existence of a particular condition. The event object can alter a condition of the block object, and vice versa. As such, a system and method for simulating event behavior in a complex digital system is envisioned. Other objects, advantages and novel features of the present invention will be apparent to those skilled in the art from the following detailed description of the invention, the appended claims, and in conjunction with the accompanying drawings.

摘要： A new user-defined object type and method of making the object type. A new object type is an m-file. M-files are files which require very little physical storage space, but appear to active processes to be a predetermined size up to the maximum user supported file size. A rule is associated with a unique file identifier such that any access of the file is also an invocation of the rule transparent to the requesting application. The rule generates code to fill the requested block of the requested file.

摘要： The problem of searching for a low cost path from a source location to a target location through a traversable region partitioned into a plurality of tiles is solved using source and target cost functions. Each tile in the traversable region is defined by boundary segments. The source cost function provides a cost for traversing from the source location to the boundary segment in question. The target cost function provides a cost for traversing from the boundary segment in question to the target location. The target cost function is estimated, and the source cost function is calculated. A path cost function is determined by adding the source and target cost functions. If the target location is a tile, then the target cost may be estimated using a convex hull of the target tile and the boundary segment in question. To facilitate the cost function calculations, multiple forms of cost function propagation between segments are disclosed.

摘要： A system for converting between parallel data and serial data is described. In the system 10, individual bits of the parallel data 12 are latched into individual registers 117. Each register 117 is coupled to a corresponding AND gate 110 which is also connected to receive phased clock signals. The output terminals of the AND gates 110 are connected to an OR gate 115. Using the system, with appropriately phased clocks, the parallel data is converted into serial data.
