摘要： Eliminating or reducing an operand line crossing penalty by performing an initial fetch for an operand from a data cache of a processor. The initial fetch is performed by allowing or permitting the initial fetch to occur unaligned with reference to a quadword boundary. A plurality of subsequent fetches for a corresponding plurality of operands from the data cache are performed wherein each of the plurality of subsequent fetches is aligned to any of a plurality of quadword boundaries to prevent each of a plurality of individual fetch requests from spanning a plurality of lines in the data cache. A steady stream of data is maintained by placing an operand buffer at an output of the data cache to store and merge data from the initial fetch and the plurality of subsequent fetches, and to return the stored and merged data to the processor.
摘要翻译：通过从处理器的数据高速缓存中执行对操作数的初始提取来消除或减少操作数线路交叉处罚。初始提取是通过允许或允许以参考四字边界未对齐的方式发生初始提取而执行的。执行用于来自数据高速缓存的相应多个操作数的多个后续提取，其中多个后续提取中的每一个与多个四字边界中的任何一个对齐，以防止多个单独提取请求中的每一个跨越多个数据缓存中的行。通过在数据高速缓存的输出处放置操作数缓冲器来存储和合并来自初始提取和多个后续提取的数据并将存储和合并的数据返回到处理器来维持稳定的数据流。

摘要： A method and system for implementing store buffer allocation for variable length store data operations are provided. The method includes receiving a store address request and at least one store data request and stepping through data operations for each of the store data requests and an address range for the store data requests to determine alignment and data steering information used to select a storage buffer destination for the data in the store data requests. The method further includes determining availability of the storage buffer by maintaining a reservation list for each storage buffer, maintaining a count of the number of available entries for each storage buffer, updating the reservation list to reflect a reservation acceptance for designated available entries, and clearing entries upon completion of the processing of store data operations. The method also includes reserving the selected storage buffer when the number of available entries meets or exceeds the number of entries required for the data.
