This paper discusses a continuous time sigma-delta modulator architecture that uses efficient time-domain quantizer and corresponding feedback element. The time-domain quantizer takes advantage of all quantization time slots to realize multi-bit quantization. Thus, the performance is enhanced while the power consumption of the quantizer is reduced. The feedback element generates feedback pulse, and...
Benefiting from the development of network technology, applications based on distributed system become more and more popular. In these applications, different copies of data are always stored in different databases, so the data synchronization becomes very important. Firstly, this paper analyzes existing data synchronization technology. And then it describes the architecture and the major advantages...
The remote file synchronization problem is how to update an outdated version of a file located on one machine to the current version located on another machine with a minimal amount of network communication. It arises in many scenarios including Web site mirroring, file system backup and replication, or web access over slow links. A widely used open-source tool called rsync uses a single round of...
