摘要： Provided are a microprocessor suitable for constructing a multi-processor system and a method for controlling the reset and processor ID of the microprocessor. The microprocessor includes decoder receiving a reset ID having a predetermined binary value and a reset signal and decoding the reset ID, an ID generator receiving the decoding result of the decoder and generating at least one microprocessor ID and a reset ID of a microprocessor serially connected to the microprocessor, and a reset vector unit selecting a reset vector according to the decoding result of the decoder. The multi-processor system is constructed such that independent microprocessors of the system respectively generate their own reset vectors and processor IDs when a reset signal is input to the multi-processor system to initialize it. Thus, all the microprocessors of the system can be simultaneously started up when the reset signal is disabled. Accordingly, a resetting process in the multi-processor system is simplified, a period of time required for starting up the microprocessor is reduced, and the multi-processor system is easily designed.

摘要： The present invention relates to an efficient snapshot technique based on a mapping for a large logical volume shared in multiple hosts. According to the present invention, problems of time delays in a conventional snapshot technique is solved by employing a FAB and an SSB, which are bits representing whether a COW operation is carried out to a mapping entry. In other words, the present invention solves the problems of delaying a write operation of corresponding volume, which is simultaneously executed when a snapshot is created, until the snapshot creation is completed. Further, in the write operation carried out after the snapshot creation, an operation of determining whether the COW operation is carried out is achieved by reading only an original mapping block by using the FAB and the SSB, without reading out the snapshot mapping block. Therefore, an additional disk access operation is decreased when carrying out a write operation to the volume in which the snapshot exists, thereby improving the performance of operation. Furthermore, in a snapshot destruction operation, the operation of determining whether the COW operation is carried out or not can be achieved without access to the snapshot mapping block, thereby preventing the degradation of performance. In case there is at least one snapshot, the determination operation can be achieved by an access to the original mapping block. Consequently, constant performance is always provided without the number of the snapshots.
摘要翻译： 本发明涉及一种基于多个主机共享的大型逻辑卷映射的高效快照技术。 根据本发明，通过采用FAB和SSB来解决传统快照技术中的时间延迟问题，它们是表示是否对映射条目执行COW操作的位。 换句话说，本发明解决了在创建快照时同时执行的相应卷的写入操作的延迟的问题，直到快照创建完成为止。 此外，在快照创建之后执行的写入操作中，通过仅使用FAB和SSB仅读取原始映射块而不读出快照映射块来实现确定是否执行COW操作的操作。 因此，当对存在快照的卷执行写入操作时，额外的磁盘访问操作减少，从而提高了操作的性能。 此外，在快照销毁操作中，可以在不访问快照映射块的情况下实现确定是否执行COW操作的操作，从而防止性能下降。 在存在至少一个快照的情况下，可以通过访问原始映射块来实现确定操作。 因此，始终提供恒定的性能，而不需要快照的数量。
