Description
Technical field
The present invention relates to the embedded system technology field, the particularly configuration store method technical field in the embedded system specifically is meant and realizes in a kind of embedded system that system configuration simplifies the method for preservation.
Background technology
In embedded system, generally all can there be some system configuration to preserve.These configurations mostly are kept at the storer that is difficult for mistake, in the FLASH flash memory.Common way is to be kept at a certain position of FLASH after the configuration compression in the existing embedded system.Though present compression algorithm is all relatively good, the configuration information big or small such as 1M possibly need the FLASH of 128K to preserve.But concerning embedded system, required shelf space is still bigger, in addition the space that can further optimize.
In the prior art, can in FLASH, mark a zone (configuration conservation zone) and be used for compressing the configuration that preservation is being used.For the resuming default setting, embedded system has been preserved a default setting a default configuration conservation zone toward contact.As, in FLASH, mark a configuration conservation zone and compress the preservation file system, in file system, preserve a default configuration again.System all uses the configuration information in the memory configurations district in operational process, and the configuration information in the memory configurations district is the copy of data in the configuration conservation zone.When preserving, the data compression in memory configurations district is saved in the configuration conservation zone.Resuming default setting if desired is just the data in the configuration conservation zone of the covering of the default configuration in file system FLASH.
The shortcoming of such store method is that the space requirement of the configuration conservation zone among the FLASH is bigger, and the content of configuration in the conservation zone largely with the default configuration conservation zone in content repeat, cause the waste of storage space.
Summary of the invention
The objective of the invention is to have overcome above-mentioned shortcoming of the prior art; Provide a kind of avoid in storer for system configuration repeat preserve; Thereby effectively reduce system configuration and preserve needed space; Reduce the requirement of the storage space of embedded system application device; And realize with low cost; Application mode is easy, and range of application realizes that comparatively widely system configuration simplifies the method for preservation in the embedded system.
The realization system configuration is simplified in the method for preservation in embedded system of the present invention; Has application apparatus in the described embedded system; Comprise storer in this application apparatus; Described storer comprises sets configuration conservation zone, default configuration conservation zone and memory configurations district, and the default system configuration store that described embedded system had is in described default configuration conservation zone.
In embedded system commonly used, the place that is modified in the configuration is often fewer, and the overwhelming majority can not be modified to.That is to say that need be saved in the data of setting in the configuration conservation zone has only a part seldom different with the default configuration conservation zone.Like this, just can be when preserving the configuration conservation zone, only that this part is different configurations is saved in the setting configuration conservation zone just passable.In system start-up, earlier the data in the default configuration conservation zone are copied to the memory configurations district, the data of setting the correspondence in the data division covering memory configuring area different in the configuration conservation zone, just obtained the current configuration that will use again.Like this, set the configuration conservation zone and just can use very little space.Thereby reach the purpose of practicing thrift system memory space.
In order to realize above-mentioned purpose, this system configuration is simplified store method and is comprised configuration read operation and configuration preservation operation.Wherein, described configuration read operation may further comprise the steps:
(11) user starts embedding system application device;
(12) embedded system reads to described memory configurations district with the described default system configuration that is stored in the default configuration conservation zone;
(13) embedded system judges whether described setting configuration conservation zone is empty, if, then get into step (15), if not, then get into step (14);
(14) embedded system reads to described memory configurations district with the described system configuration of setting the configuration conservation zone that is stored in, and covers the corresponding information in original default system configuration;
(15) the described embedding system application device of configuration operation in the described embedded system application memory configuring area;
Described configuration is preserved operation and may further comprise the steps:
(31) content in embedded system more described memory configurations district and the described default configuration conservation zone deposits wherein different contents in described setting configuration conservation zone.
The realization system configuration is simplified in the method for preservation in this embedded system, and described configuration is preserved in the operation further comprising the steps of before in described step (31):
(30) embedded system receives according to user's operation and preserves configuration-direct or shutdown command.
The realization system configuration is simplified in the method for preservation in this embedded system, and described method also comprises the configuration read operation and dispose the configuration settings of preserving between the operation and operate that described configuration settings operation may further comprise the steps:
(21) user carries out the embedded system configuration modification through described application apparatus;
(22) embedded system deposits the configuration of being revised in described memory configurations district, and covers the corresponding information in original configuration.
Adopted and realized in the embedded system of this invention that system configuration simplifies the method for preservation; Owing to comprise in the storer of its application apparatus and set configuration conservation zone and default configuration conservation zone; And configuration modification information stores that only will be different with default configuration information is in described default configuration conservation zone; Thereby avoided the preservation that repeats fully for system configuration; Require lessly for the storage space of the application apparatus of embedded system, overcome the problem of waste of storage space in the prior art.When being written into configuration, only need read default configuration earlier, read again and set configuration, can accomplish.Therefore, realize in the embedded system of the present invention that system configuration simplifies the method for preservation and realize with low costly, application mode is easy, and range of application is comparatively extensive.
