摘要： An information handling system includes a processor with a bifurcated unified issue queue that may perform unified issue queue VSU store instruction dependency operations. The bifurcated unified issue queue BUIQ maintains VSU store instructions in the form of internal operations data. The BUIQ includes a unified issue queue UIQ 0 and a unified issue queue UIQ 1. The BUIQ may manage a particular VSU store instruction from one UIQ to determine data dependencies and employ the other UIQ to determine address dependencies of that particular VSU store instruction. The UIQs employ a dependency matrix including a dependency array. The dependency array data maintains both data and address dependency information. The particular VSU store instruction issues to execution units such as VSUs for data dependency information and load store units (LSUs) for address dependency information. A particular VSU store instruction may execute to provide data dependency information independent of address dependency information.

摘要： A method is provided for evaluating two or more instructions in an out of order issue queue during a particular cycle of the queue, to select an instruction for issue during the next following cycle. If an instruction was previously designated to issue during the particular cycle, one or more instructions in the queue are evaluated to determine if any of them are dependent on the designated instruction. For the evaluation, each instruction placed into the queue is accompanied by corresponding logic elements that provide destination to source compares for the instruction. In an embodiment comprising a method, the oldest ready instruction in the queue during a particular cycle is identified. When an instruction was previously designated to issue during the particular cycle, it is determined whether at least a first instruction in the queue complies with each condition in a set of conditions, the set including at least the conditions that the first instruction has a dependency on the designated instruction, and that the first instruction is older than the oldest ready instruction. The first instruction is selected for issue during the next following cycle only if the first instruction complies with each condition in the set.

摘要： A processor including a register file and method for computing flush masks in a multi-threaded processing system provides fast and low-logic-overhead computation of a flush result in response to multiple flush request sources. A flush mask register file is implemented by multiple cells in an array where cells are absent from the diagonal where the column index is equal to the row index. Each cell has a vertical write enable and a horizontal write enable. When a row is written to validate that row's tag value, the column having an index equal to the row selector is automatically reset (excepting the absent cell mentioned above) . On a read of a row, a wired-AND circuit provided at each column provides a bit field corresponding to other rows that have been written since a last reset of the row, which is a flush mask indicating newer tags and the selected tag.

摘要： A data processing system (10) has a processor (11), a display device (15), and a user input arrangement (17) which includes a pointer control device (19) such as a mouse. An edit function input is entered through the user input arrangement (17) and a target to be edited is identified in response to the edit function input. The target comprises some displayed object that is specified by proximity to a system pointer (29) at the time the edit function input is received. The edit function input defines an edit operation to be performed by the data processing system (10) on the identified target. After receiving the edit function input and responding to the input by identifying the target, the method includes determining a state of the target which indicates whether or not the edit operation is currently applied to the target. If the state of the target indicates that the edit operation is not currently applied to the target, the method includes applying the edit operation to the target. In this way, the edit operation is applied to the target without first having to explicitly select the target.

摘要： A processor and method of fetching data within a data processing system are disclosed. According to the method, a first difference between a first load address and a second load address is calculated. In addition, a determination is made whether a second difference between a third load address and the second load address is equal to the first difference. In response to a determination that the first difference and the second difference are equal, a fourth load address, which is generated by adding the third address and the second difference, is transmitted to the memory as a memory fetch address. In an embodiment of the data processing system including a processor having an associated cache, the fourth load address is transmitted to the memory only if the fourth load address is not resident in the cache or the target of an outstanding memory fetch request.

摘要： An information handling system includes a processor with an issue unit (IU) that may perform instruction dependency tracking for successive instruction issue operations. The IU maintains non-shifting issue queue (NSIQ) and shifting issue queue (SIQ) instructions along with relative instruction to instruction dependency information. A mapper maps queue position data for instructions that dispatch to issue queue locations within the IU. The IU may test an issuing producer instruction against consumer instructions in the IU for queue position (QPOS) and register tag (RTAG) matches. A matching consumer instruction may issue in a successive manner in the case of a queue position match or in a next processor cycle in the case of a register tag match.
