Abstract :
Aiming at the feature of demand on thousand-class large throughput real-time data storage, millisecond storage period and strong real-time multi-task scheduling, introduce a cache structure based on circular queue to avoid problem of low precision of storage data caused by instability of hardware equipments and pose dynamic priority scheduling strategy based on margin function on this basis, thus to increase efficiency of real-time multi-task scheduling of the system. Experiment results show that such calculation method can increase mass high-speed storage and obtain satisfied real-time precision that is efficient and feasible.
