Fig. 2 is the operating process of the data update apparatus shown in Fig. 1.
Embodiment
Refer to shown in Fig. 1, the data update apparatus 100 that an embodiment of the invention relate to, it includes initial buffer memory 110, control module 120 and storer 130.Wherein initial buffer memory 110 is for storing initial data.Control module 120 also includes data-interface 121, decoder module 123 and read-write interface 125.Storer 130 is for the target data of storage update.Be directed to the target data of the renewal be stored in storer 130, define more new data and primary data.Wherein primary data refers to the data needing to be stored in storer and then wait for local updating.If its local has been capped more new data, then can obtain the target data upgraded.And more new data is normally sent out by a data sending terminal 150, then covered by control module in the part primary data be stored in storer, and then the target data of renewal can be obtained.
When carrying out Data Update, the operating process 200 of the data update apparatus shown in Fig. 1 refers to shown in Fig. 2.It includes following steps, primary data is stored in initial buffer memory 210, the primary data stored is stored in storer 220 in initial buffer memory, data sending terminal carries out coding 230 to more new data and the more new data of coded format sends to storer to carry out Data Update 240 by control module by data sending terminal.
In step 220, the primary data stored in initial buffer memory 110 is stored in the designated memory space of target memory 130 by the read-write interface 125 of control module 120.The address of the storage space of wherein specifying in storer and the address of initial memory are one to one, and read-write interface 125 is high-speed interfaces, and storage speed can be relatively quick.
In step 230, more new data is sent out by a data sending terminal 200.Wherein data sending terminal 200 can be encoded to more new data, then will more send out by new data with coded format, further can save the data transmitting time of transmitting terminal like this, to avoid because its data transmission speed is relatively slow as far as possible, and cause the renewal frequency affecting target data.
Because target data obtains the local updating of primary data.The content of different address according to the difference of memory address, can be compiled as different coded datas by these data upgraded.And for address continuous print update content, can be organized among a coded data.Further, the bit wide of coded data can adjust according to practical application.Cataloged procedure can have been come by the known software approach of industry or hardware approach.Further, each coded data comprises initial address message (IAM), address size information and data content information.Address size information is shown to be carries out content update to single address, or upgrades continuation address content.Such as, if it is 1, then single address update content is indicated as.
In step 240, the coding including update content is first input in decoder module 123 by the data-interface 121 of control module 120.Decoder module 123 is decoded to coding, parse address information wherein and corresponding content thereof, then be sent in storer 130 by read-write interface 125, storer 130 is according to address information, its content is written on this address, completes the renewal to the initial digital content that this address stores.If the address size information in coded data is not 1, then it is the renewal to content on multiple address continuous after this start address.After all coded datas have been performed, are then exactly complete the renewal to the primary data stored in target memory 130 designated memory space, and then have also just obtained the target data of renewal.
In the present invention, because data sending terminal just sends more new data, but not real data; And, or adopt the form of coding to send, thus greatly reduce volume of transmitted data, thus saved data transmitting time, and that cause Data Update frequency low problem slow due to himself data transmission speed can be effectively reduced like this.And then decrease the time of each refresh memory.
The present invention, the data being specially adapted to more new memory internal memory storage only need partial content more news.In the data stored, the content that upgrades is fewer, then more can show the efficiency that the inventive method carries out Data Update to it higher.
