Method of multiplexed data reading/writing suitable for video-on-demand system |
摘要 |
A method of multiplexed data reading/writing capable of admitting more than n requests simultaneously in a configuration in which m sets of n-fold multiplexed sub-systems are provided in parallel. Each data is divided into a plurality of segment data which are stored in a prescribed order among the memory devices, and m memory control units are connected with mxn input/output channels selectively and sequentially in units of time-slots such that each memory control unit is connected with each of input/output channel at least once within a prescribed period. Then, the reading/writing operations of the segment data stored in the memory devices are carried out by making accesses from m memory control units in parallel at each time-slot such that each segment data read/written by each memory control unit from/into one of the memory devices connected thereto at each time-slot is transmitted to/from one of mxn input/output channels connected thereto at each time-slot.
