Abstract: A method, an apparatus, and a programmable apparatus for incremental update are provided. The method for incremental update includes: according to data structures of a first program object and a second program object, comparing a basic element of the first and second program objects to determine differential information of the basic element between the first and second program objects, where a data structure describes a manner of the basic element for constructing a corresponding program object from the first and second program objects; generating incremental information according to the differential information of the basic element, where the incremental information at least includes update information for the basic element of the first program object; and releasing the incremental information to an update terminal, such that the update terminal updates the first program object to the second program object according to the incremental information.
