Embodiment Construction
[0051] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0052] In the prior art, in order to solve the compatibility problem of the new instruction set, a software version may be compiled for each type of hardware device according to the CPU type of the hardware device. The hardware device may be a device with an embedded system, such as a set-top box. Then, when the hardware device is turned on, a certain version of the application software needs to be started. The implementation process of selecting the software version can be to identify the model of the hardware device through a script when the hardware device is turned on, and select the software version corresponding to the model. However, this method is only applicable to limited hardw...

The invention discloses a method for realizing software version selection, which is used for providing a general method for selecting a software version compatible with a CPU. The method comprises thefollowing steps of selecting a current software package from a software package collection, and respectively compiling and obtaining each software package in the software package collection from different number of instruction sets; determining whether the instruction set supported by the CPU is compatible with the instruction set used for compiling the current software package; if the instruction set supported by the CPU is compatible with the instruction set used for compiling the current software package, running the current software package; if the instruction set supported by the CPU isincompatible with the instruction set used to compile the current package, removing the current package from the package set and determining the current package and subsequent steps in the package setuntil the current package is run or the package set is empty. The present application also discloses an apparatus for realizing software version selection, a storage medium and a computer program product.
Description
technical field [0001] The present application relates to the field of embedded technology, in particular to a method, device, storage medium, and program product for realizing software version selection. Background technique [0002] With the updating of the central processing unit (Central Processing Unit, CPU), new instruction sets are continuously introduced into new CPU architectures. The instruction set is a hard program stored inside the CPU to guide and optimize CPU operations. With these instruction sets, the CPU can run more efficiently. While the faster computing speed brought by the new instruction set, it also brings some compatibility problems: software programs compiled with the new instruction set often cannot run on the old central processing unit. [0003] In order to solve the compatibility problem of the new instruction set, in the prior art, a software version can be compiled for each type of hardware device according to the CPU type of the hardware dev...
