摘要： A cache coherent data processing system includes at least first and second coherency domains. The first coherency domain contains a memory controller, an associated system memory having a target memory block identified by a target address, and a domain indicator indicating whether the target memory block is cached outside the first coherency domain. During operation, the first coherency domain receives a flush operation broadcast to the first and second coherency domains, where the flush operation specifies the target address of the target memory block. The first coherency domain also receives a combined response for the flush operation representing a system-wide response to the flush operation. In response to receipt in the first coherency domain of the combined response, a determination is made if the combined response indicates that a cached copy of the target memory block may remain within the data processing system. In response to a determination that the combined response indicates that a cached copy of the target memory block may remain in the data processing system, the domain indicator is updated to indicate that the target memory block is cached outside of the first coherency domain.

A scope of broadcast of a subsequent operation is predictively selected by reference to the predictor.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method and processor system that substantially enhances the store gathering capabilities of a store queue entry to enable gathering of a maximum number of proximate-in-time store operations before the entry is selected for dispatch. A counter is provided for each entry to track a time since a last gather to the entry. When a new gather does not occur before the counter reaches a threshold saturation point, the entry is signaled ready for dispatch. By defining an optimum threshold saturation point before the counter expires, sufficient time is provided for the entry to gather a proximate-in-time store operation. The entry may be deemed eligible for selection when certain conditions occur, including the entry becoming full, issuance of a barrier operation, and saturation of the counter. The use of the counter increases the ability of a store queue entry to complete gathering of enough store operations to update an entire cache line before that entry is dispatched to an RC machine.

摘要： 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.

摘要翻译： 液体燃料喷射泵送装置包括由挺杆组件和旋转凸轮可操作的可往复运动的泵柱塞。 挺杆组件包括可在孔内滑动的圆柱形主体，该主体承载支撑可与凸轮啮合的滚子的十字销。 十字销具有倾斜的端部，使得如果其在暴露于孔的端部之前轴向移动，则其将接合孔并且轴向移动到其正确位置。 通过设计用于提供最大柱塞移动的凸轮，销被暴露出可观的时间，并且可能发生销和孔的严重磨损。 因此，凸轮被设计成允许柱塞的向外运动，然后保持柱塞，直到需要进行柱塞的向内运动之前。 当柱塞保持时，泵的填充口至少部分地不被覆盖。 凸轮具有后缘，其包括第一部分，在该第一部分期间柱塞可以向外移动;第二部分，其中柱塞被保持抵抗向外的运动;第三部分允许完全向外运动。

摘要： 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.
