Abstract: A data storing method includes providing a storage space, receiving a data stream, establishing a cluster link when the data stream is stored into the storage space, and before the data stream is completely stored in the storage space, storing a cluster number of a specific node in the cluster link and information about a cluster following the specific node, and setting the content of the specific node as an EOF. A data storage system thereof can access a real-time data stream stored in the storage space, or release the occupied space in the storage space through deleting the file of the real-time data stream, even if the real-time data stream is interrupted abnormally during storage.

Abstract: This invention discloses a reduced-width, low-error multiplier that can be used in Digital Signal Processing (DSP). Specifically, this invention relates to a reduced-width, low-error multiplier capable of processing digital signals of communication systems such as a timing recovery circuit, a carrier recovery circuit, and a FIR filter, etc. This invention derives a binary compensation vector to compensate for the error caused by the reduction of area without any hardware overhead, and implements the compensation structure of an Array and a Booth multiplier to reduce hardware complexity.

Abstract: This invention purposes a reduced-width low-error multiplier that can be used in the DSP (Digital Signal Processing) approach of digital communication system. We derive a binary compensation vector to compensate the error caused by the reduction of area without any hardware overhead. We also implement the compensation structure in Array and Booth multiplier to reduce hardware complexity.
