The invention relates to a heterogeneous real-time information processing system design method, a distributed embedded system is formed by a plurality of heterogeneous embedded systems, namely a plurality of nodes, each node executes a subtask, and all the subtasks form a currently deployed task. When the subtask of any node changes, program updating needs to be carried out on at least one chip in the corresponding node so as to meet the subtask requirement. The method comprises the steps of firstly comparing a new program with an existing program of a to-be-updated chip to obtain an initial updating part and an initial updating area; then, according to the initial updating area and the coverage degree of the Flash, the updating granularity is adaptively and dynamically adjusted according to the principle of shortest updating time, an optimized updating part and a corresponding optimized updating area are determined, and the superior control equipment of the corresponding node sends a new program to the to-be
