摘要： A most recently used bit (25) is used to determine if a data transfer should occur from a fill buffer (20) into a data memory (32) in a cache (15). If the data to be displaced in the data memory (32) has been referenced more recently than the data present in the fill buffer (20), then the transfer should not occur. When a cache miss does occur, a control register (50) is used to determine the conditions for loading the fill buffer (20).

摘要翻译： 最近使用的位（25）用于确定数据传输是否应当从缓冲器（20）到缓存器（15）中的数据存储器（32）中发生。 如果在数据存储器（32）中要移位的数据比填充缓冲器（20）中存在的数据更近被引用，则不应该发生传送。 当发生高速缓存未命中时，使用控制寄存器（50）来确定用于加载填充缓冲器（20）的条件。

摘要： A method for reducing signed load latency in a microprocessor has been developed. The method includes transferring a part of data to an aligner via a bypass, and generating a sign bit from the part of the data. The sign bit is transferred to the aligner along the bypass, and the data is separately transferred to the aligner along a data path.

摘要： Methods and a system to acquire and perform write validation of data generated by one or more networked host nodes to perform secondary storage are disclosed. According to one embodiment, a method to passively acquire and perform write validation of data generated by one or more networked host nodes to perform secondary storage in a SAN-based data storage and recovery network includes generating data to store in primary storage. The method further includes generating metadata describing the data generated to store in primary storage, sending the data and metadata to a primary SAN storage device, acquiring passive access to data traveling a data path between a generating node and the primary SAN storage device, the data mirrored over an access line to a secondary storage server. The method further includes receiving, at the secondary storage server, an exact copy of a data stream that passes a splitter.
