Method for accelerating storage of multi-path on-satellite load files
The invention provides a method for accelerating storage of multiple paths of on-board load files. The storage of the multiple paths of on-board load files is accelerated by adopting a processing method of two-stage caching and multi-thread line production. And in the load data receiving thread, the...

| description | The invention provides a method for accelerating storage of multiple paths of on-board load files. The storage of the multiple paths of on-board load files is accelerated by adopting a processing method of two-stage caching and multi-thread line production. And in the load data receiving thread, the first-stage cache receives each path of load data packet from an external interface in an undifferentiated manner through the mutual cooperation of a circular queue and counting semaphore and the control of a read-write pointer. And in the load data processing thread, the second-level cache adoptsdouble-cache alternate reading and writing for each path of load data, and is matched with the state machine to control the empty, receiving and storage states of each cache. And in the load data storage thread, writing the load data in the cache in the storage state into a file for storage according to the size of a memory page. The first-level cache quickly receives multiple paths of external load data, the second-level |
