Embodiment Construction

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Download and run the code that can be run directly, which has the characteristics of less code amount and high operation efficiency. By analyzing the existing technology, taking the game as an example, some codes of the game can be compiled and linked into target codes that can be run directly. The core of the present invention is to enable the predetermined program to directly obtain the driver function address of each underlying device, and no longer need to directly call the driver function address during the device initialization process, so that the dow...

Abstract

The invention relates to a non-interpretation type dynamic downloading-running method. The method comprises the steps of defining a function pointer as a task entry function of a preset program, setting an initial value of a driving function pointer in the preset program as an address corresponding to a driving function, and the like. The method enables the preset program to directly obtain the driving-function address of each bottom-layer device and no longer needs a device initialization process to directly call the driving-function addresses so as to directly run the downloaded preset program as a component or a process of the prior program.

Description

technical field [0001] The present invention relates to program operation, more specifically, relates to a non-interpretation dynamic downloading operation method. Background technique [0002] In many cases, programs need to be dynamically downloaded and run, for example, a game program is downloaded from a TS stream or from the Internet to a set-top box for running. This requirement can be realized by independently developing the game into an executable file on an operating system that supports multi-process scheduling, and downloading it to the device as a new process for scheduling and execution. However, for a considerable number of embedded operating systems that do not support multi-process scheduling, generally only an interpreter is used to interpret and run, such as a Java virtual machine or a JavaScript interpreter. However, this method has the disadvantages of high cost and low efficiency. [0003] Embedded systems generally do not support multi-process schedul...
