Abstract: With the improvement of satellite computer integration and computing capacity, the satellite integrated electronic computer has the ability to realize satellite management function and GNC function. The scale and complexity of satellite integrated electronic application software become larger and more complex，which puts forward high requirements for its architecture design. The problem existing in the realization method of tele command function is analyzed. And the method based on Hash table +linked list is proposed to realize the mechanism and decoupling, which improves the performance, expansibility and maintainability of the software. Good results are achieved through simulation and practical application in models.

Key words: sate integrated electronic, decoupling tele-command, Hash table, linked list
