Embodiment
Below in conjunction with figure and specific embodiment the present invention is further illustrated, but not as limiting to the invention.
Along with the development of semiconductor technology, the area of embedded MASK ROM (i.e. embedded MASK ROM (read-only memory)) is more and more less, capacity is increasing, can be used for storing increasing data, and the reading speed of MASK ROM is faster than NAND Flash (i.e. nand flash memory), therefore can be integrated in EMMC/UFS controller, be used for storing data, thus improve the reading speed of EMMC/UFS card, as shown in Figure 4.
Add the basic structure of the EMMC/UFS card of embedded MASK ROM as shown in Figure 4, the basic structure of EMMC is wherein only shown, both basic structure is identical, storer in addition on UFS card also comprises NOR Flash or SD card (i.e. SD Card), and such EMMC/UFS card comprises two kinds of memory device NAND Flash and embedded MASK ROM and package interface.Therefore a part of data of the user be stored in NAND Flash can be put into embedded MASK ROM (in an embodiment of the present invention by us, the data of subsequent load are divided into master data and the auxiliary data relative to master data, wherein master data comprises identical content or the non-update content of the different operating system/system-level application program of mobile terminal device, all the other contents are auxiliary data), the such as data such as operating system and system-level application program, we divide two aspects so that the application of this method to be described for operating system below, system-level application instance is identical, repeat no more.
For same operating system (here for andriod), we divide following two aspects to illustrate:
Different andriod mobile phone production firms, operating system is substantially different, but certainly there is identical content in them, such as kernel, therefore we can put into embedded MASK ROM these identical parts, like this when performing the operating system of mobile terminal device, can directly load from embedded MASK ROM, and need not load from NAND Flash, and the speed loaded from embedded MASK ROM is faster than the speed loaded from NAND Flash, therefore can improve the toggle speed of system, improve Consumer's Experience.
For the mobile phone production firm of same andriod operating system, during each renewal rewards theory system, some specific part in operating system forever remains unchanged or the most of the time does not upgrade (i.e. non-update), therefore these parts can be put into embedded MASKROM by us, due to these parts, the constant or most of the time does not upgrade forever, the erasable number of times of the storage block at these data places can be caused like this well below other storage blocks, under loss equalizing algorithm, these part place storage blocks need to transfer in the higher storage block of other erasable number of times, cause unnecessary erasable.Be received within embedded MASKROM by the identical content of the different operating system of mobile terminal device/system-level application program or non-update in the present invention, can avoid unnecessary erasable, thus improve the performance of NAND Flash.
For different operating system, such as andriod, IOS, Windows Phone etc., substantially not identical between often kind of operating system, but each operating system has two features above-mentioned, therefore when embedded MASK ROM capacity is enough large, the data content meeting the above two dot characteristics in each operating system can all be put into embedded MASK ROM by us, as shown in Figure 5.Suppose that the data content meeting the above two dot characteristics in andriod system (i.e. the first system in Fig. 5) is A, the data content meeting the above two dot characteristics in IOS system (i.e. second system in Fig. 5) is B, we put into embedded MASK ROM this two parts content of A and B, if when EMMC/UFS card is used for andriod system like this, data content A is activated, other parts are not activated, although there is certain redundancy waste, but improve the toggle speed of andriod system, improve EMMC/UFS and read performance; If when EMMC/UFS card is used for IOS system, data content B is activated, and other parts are not activated, and improves the toggle speed of IOS system, if EMMC/UFS is applied to other operating system, situation is identical, repeats no more.So no matter after, which kind of operating system EMMC/UFS card is applied to, and can improve the toggle speed of system.
If the embedded MASK ROM in EMMC/UFS card is only used for storing the data content meeting above-mentioned two dot characteristics in a kind of operating system (for andriod), so have certain limitation, because when embedded MASK ROM only stores these data in andriod system, these EMMC/UFS cards can only improve the toggle speed of andriod system, can not improve toggle speed for other operating systems, therefore can store to these EMMC/UFS meeting the data of the above two dot characteristics in andriod system has certain warehousing pressure, if and store in several operation systems the data content meeting above-mentioned two dot characteristics in Embedded MASK ROM in EMMC/UFS card, such as andriod, IOS, Windows Phone etc., the toggle speed of andriod system can be improved when so EMMC/UFS is used for the smart machine of andriod system, the toggle speed of IOS system can be improved during smart machine for IOS system, the toggle speed of Windows Phone can be improved during smart machine for Windows Phone system, as long as store the data meeting above two dot characteristics of corresponding operating system in the embedded MASK ROM of therefore EMMC/UFS card, just can improve the toggle speed of corresponding system, and the utilization factor of Embedded MASK ROM also reaches 100%.
Generally, in operating system or the system-level application storage NAND Flash in EMMC/UFS, suppose that operating system or system-level application program are data X, the data meeting the above two characteristic are data Y, specifically as shown in Figure 6, in FTL, in address mapping table, the address of data Y is addr1, corresponding address mapping table as shown in Table 1:
Table one
When the data Y of two dot characteristics more than meeting is put into Embedded MASK ROM, specifically as shown in Figure 7, and the data of address mapping table in FTL also will make corresponding amendment, now in FTL, in address mapping table, the address of data Y is addr2, and corresponding address mapping table as shown in Table 2.
Table two
We illustrate above two kinds of situations respectively for two examples below.For same operating system (for andriod), here we are for MIUI system (i.e. the 3rd system) and Flyme system (i.e. Quaternary system system), for MIUI system and Flyme system, the kernel of these systems is all that the kernel Core_A (i.e. core A) of the standard andriod system issued by Google determines, and for MIUI system or Flyme system, there is the part that some most of the time do not upgrade in these operating systems, suppose that the content that the MIUI system most of the time do not upgrade is MIUI_A (i.e. the 3rd system A), the content that the Flyme system most of the time does not upgrade is Flyme_A (i.e. Quaternary system system A), generally Core_A, these data of MIUI_A and Flyme_A are all stored in NAND Flash, directly read from NAND Flash in time reading these data, in the present invention, we are Core_A, MIUI_A and Flyme_A puts into Embedded MASK ROM, upgrade the address mapping table in FTL, and the Core_A marked in NAND Flash, MIUI_A, Flyme_A is invalid, can directly read from Embedded MASK ROM when these parts will be read like this, thus improve the speed of the startup of system, as shown in Figure 8.
For different operating system (for andriod and IOS), andriod system and IOS system are substantially not identical, but they have two features mentioned above, suppose that the kernel of IOS system is Core_B (i.e. kernel B), the part that most of the time does not upgrade is IOS_B (i.e. second system B), for andriod system, we analyze in the above example, for IOS system, the part IOS_B that the kernel Core_B of IOS and most of the time do not upgrade also can be put into embedded MASKROM by us, upgrade the address mapping table in FTL, corresponding partial invalidity in mark NAND Flash.Like this when EMMC/UFS is applied to MIUI system, Core_A and MIUI_A stored in embedded MASKROM can be activated, and other parts are not activated; When EMMC/UFS is applied to Flyme system, Core_A and Flyme_A stored in embedded MASK ROM can be activated, and other parts are not activated; When EMMC/UFS is applied to IOS system, Core_B and IOS_B stored in embedded MASK ROM can be activated, and other parts are not activated, as shown in Figure 9, identical with andriod/IOS for other operating systems.
Therefore, when the data that operating system or system-level application program meet above two dot characteristics are stored in embedded MASK ROM, for improving the step summary of EMMC/UFS card reading performance be then:
Step S1, there is different operating system (in an embodiment of the present invention by some in advance, this different operating system also comprises the same operating system with part different content except several operation systems) mobile terminal device power on after need load data be divided into master data and the auxiliary data relative to master data, and by primary data store to embedded MASK ROM, auxiliary data is stored in NAND Flash.
Step S2, after arbitrary mobile terminal device powers on, judge that mobile terminal device needs the data loaded whether to be stored in embedded MASK ROM according to address mapping table, if, (from embedded MASK ROM, load operation system/system-level application program is in internal memory then to load data from embedded MASK ROM, to be loaded on sheet in buffer memory again from internal memory, performed by processor), otherwise load data from NAND Flash, as shown in Figure 10.
We mention same operating system some part in each renewal and forever to remain unchanged or the most of the time does not upgrade above, therefore these parts are put into embedded MASKROM by us, if but the part that do not upgrade of these mosts of the time there occurs change (non-update Content Transformation is update content) in operating system when certain operating system update, and embedded MASK ROM is only readable can not write, so again data can not be write inside embedded MASK ROM, so at this moment just need update content to be write (effective content) in NANDFlash, non-update content is still stored in embedded MASK ROM, and the address mapping table again upgraded in FTL, make to be stored in the non-update content invalid in embedded MASK ROM.We give an example explanation below.
We are for IOS system, and suppose that the part that most of the time in IOS system do not upgrade is IOS_B (i.e. second system B), IOS_B is stored in the embedded MASK ROM of EMMC/UFS.Suppose that IOS_B there occurs change when certain operating system update, so can not write because Embedded MASK ROM is only readable, so the content upgraded must be stored in NAND Flash, upgrade the address mapping table in FTL simultaneously, and the IOS_B marked in embedded MASK ROM is invalid, the IOS_B arranged in NAND Flash is effective, directly reads from NAND Flash, specifically as shown in figure 11 when reading IOS_B.
In sum, the invention discloses a kind of EMMC/UFS card and improve the method that performance read by EMMC/UFS card, by adding an embedded MASK ROM (read-only memory) in EMMC/UFS controller chip, and after being powered on by the mobile terminal device with different operating system, need the data loaded to be divided into master data and the auxiliary data relative to master data, data are stored in embedded MASK ROM (read-only memory), auxiliary data is stored in nand flash memory, after arbitrary mobile terminal device powers on, judge that this mobile terminal device needs the data loaded whether to be stored in embedded MASK ROM (read-only memory), if, then load data from embedded MASK ROM (read-only memory), because faster than the speed reading data in nand flash memory from the speed of the reading data embedded MASK ROM (read-only memory), thus improve the OnNow speed of mobile terminal device system.
