This invention proposes a high-performance collaborative processing method for ultra-high precision pointing measuring instruments. It consists of a master-slave processor. The master processor ensures periodic update rates through external communication, while the slave processor handles complex algorithms and transmits results to the master to improve its real-time algorithm performance. The master software is designed with a multi-task architecture to ensure real-time performance. A "master-slave interaction task" is periodically initiated, triggering a data reception interrupt on the slave and completing master-slave data interaction. Other tasks handle real-time algorithms and communication. The master-slave interaction task has a timeout exit mechanism, and its execution is determined by the timeout status of other tasks at the timed start. To ensure data transmission reliability, the master-slave communication bus uses unidirectional transmission and reception to avoid transmission conflicts caused by duplex mode. Data transmission uses checksums, and data to be sent in multiple periods is packetized and assigned sequence numbers to avoid duplicate reception or data loss. This invention can be widely applied to embedded platforms using a master-slave dual-processor architecture.
