A digital system includes one or more design entities containing a functional portion of the digital system. Within a configuration database, one or more configuration entities are instantiated. The configuration entities including an Error checking Dial (EDial) having a plurality of input latches within the digital design and a plurality of output latches within the digital design. The EDial has an associated function defining a relationship between values of the input latches and values of the output latches. An instance of the EDial in the configuration database is accessed to access the values of the output latches in the digital design.

A cache coherent data processing system includes at least first and second coherency domains each including at least one processing unit. The first coherency domain includes a first cache memory and a second cache memory, and the second coherency domain includes a remote coherent cache memory. The first cache memory includes a cache controller, a data array including a data storage location for caching a memory block, and a cache directory. The cache directory includes a tag field for storing an address tag in association with the memory block and a coherency state field associated with the tag field and the data storage location. The coherency state field has a plurality of possible states including a state that indicates that the memory block is possibly shared with the second cache memory in the first coherency domain and cached only within the first coherency domain.

A cache coherent data processing system includes at least a first cache memory supporting a first processing unit and a second cache memory supporting a second processing unit. The first cache memory includes a cache array and a cache directory of contents of the cache array. In response to the first cache memory detecting on an interconnect a broadcast operation that specifies a request address, the first cache memory determines from the operation a type of the operation and a coherency state associated with the request address. In response to determining the type and the coherency state, the first cache memory filters out the broadcast operation without accessing the cache directory.

According to a one method of simulation processing, a file is utilized to describing a hardware description language (HDL) simulation model of a design. The file includes one or more statements describing a count event and identifying the count event as an outlying count event. From the file, a count event counter for the outlying count event is created within HDL instrumentation of the simulation model. The design is then simulated utilizing the HDL simulation model, and occurrences of the outlying count event are counted within the count event counter to obtain a count event value. In response to receiving the count event value of the outlying count event, the count event value is recorded within a data storage subsystem based on whether the count event value of the outlying count event exceeds a previously recorded count event value.

A processing unit for a multiprocessor data processing system includes a processor core including a store-through upper level cache, an instruction sequencing unit that fetches instructions for execution, a data register, and at least one instruction execution unit. The instruction execution unit, responsive to receipt of a load-reserve instruction from the instruction sequencing unit, executes the load-reserve instruction to determine a load target address. The processor core, responsive to the execution of the load-reserve instruction, performs a corresponding load-reserve operation by accessing the store-through upper level cache utilizing the load target address to cause data associated with the load target address to be loaded from the store-through upper level cache into the data register and by establishing a reservation for a reservation granule including the load target address.

A nasal tube retaining system having a flexible member with a magnet attached to the first end for insertion into the first nostril of the patient, a tape portion attached to an end of the flexible member, a guide for guiding the tape portion through a portion or all of the flexible member, a rod, and a retrieving member with a magnetic distal end for insertion into the second nostril of the patient to retrieve the flexible member. The system further includes a fastening means to secure the nasal tube to the tape portion.

A method is disclosed of associating a mapping function with a configuration construct of a digital design defined by one or more hardware description language (HDL) files. According to the method, in the HDL files, a configuration latch is specified within a design entity forming at least a portion of the digital design. In addition, a Dial is specified that defines a relationship between each of a plurality of input values and a respective one of a plurality of different output values. The HDL files also include a statement that instantiates an instance of the Dial in association with the configuration latch such that a one-to-one correspondence exists between a value contained within the configuration latch and an input value of the instance of the Dial. The HDL files further include a statement associating the Dial with a mapping function that applies a selected transformation to values read from or written to the instance of the Dial.

A liquid fuel injection pumping apparatus comprises a reciprocable pump plunger operable by a tappet assembly and a rotary cam. The tappet assembly includes a cylindrical body slidable within a bore, the body carrying a cross pin which supports a roller engageable with the cam. The cross pin has reclined ends so that if it moves axially while exposed beyond the end of the bore it will engage the bore and move axially to its correct position. With cams designed to give maximum plunger movement the pin is exposed for an appreciable time and heavy wear of the pin and bore can occur. The cam is therefore designed to allow outward movement of the plunger but then to hold the plunger until just before inward movement of the plunger is required to take place. Whilst the plunger is held the filling port of the pump is at least partly uncovered. The cam has a trailing flank which comprises a first part during which the plunger can move outwardly, a second part during which the plunger is held against outward movement and a third part which allows the full outward movement.

A method is provided for transmitting an electronic mail (e-mail) message from a sender having a non-ASCII e-mail address to a recipient. The method comprising following steps. An e-mail directory associated with a requested primary e-mail address, having a non-ASCII form, and a corresponding alternate e-mail address having an ASCII form, is established. The alternate e-mail is generated from the primary e-mail address using a reversible encoding scheme having a one-to-one relationship. The e-mail message and the primary e-mail address are transmitted to the recipient via a plurality of mail delivery elements. The alternate e-mail address is transmitted to a mail delivery element incapable of processing non-ASCII characters. The alternate e-mail address is for use by the mail delivery element to identify the sender and deliver the e-mail message to the recipient for display. A transmission e-mail server for implementing the method is also provided.
