Read module 14 is used for after system 100 starts, receiving the preparatory reading order from main frame 10, and in the free time of said solid state hard disc 10 log-on data in the Flash medium 11 being sent to DRAM buffer memory 12 in advance.Preamble is explained; After system 100 started, main frame 10 began DRAM buffer memory 12 reading of data from hard disk 20, and solid state hard disc 10 section of having free time after initialization is accomplished; This moment, read module 14 received preparatory reading order in advance; According to the sequencing of system's 100 log-on datas, promptly sequential query is write down logical page address LPA, in advance from Flash medium 11 reading section data to DRAM buffer memory 12.In conjunction with Fig. 4 B; Further; Main frame 20 from DRAM buffer memory 12 reading of data to once more from time of DRAM buffer memory 12 reading of data also be the free time of solid state hard disc 10; This section is in the period, and aforesaid operations is carried out in read module 14 circulations in advance, that is: will be from Flash medium 11 reading section log-on datas to DRAM buffer memory 12.When system 100 started, main frame 20 read log-on data from the DRAM buffer memory, and read module 14 circulations read DRAM buffer memory 12 with the log-on data that stores on the Flash medium 11 in advance, improve data read rates whereby, reduce the system start-up time.
Be more preferably, among the embodiment of the utility model, log-on data processing module 13 comprises that also one arranges submodule 132, is used for said log-on data is arranged in each passage of said Flash medium 11 by boot sequence uniformly.The channel data that need to prove the Flash medium of prior art is arranged irregular, shown in Fig. 5 A, can influence preparatory reading speed greatly like this.It is evenly distributed as much as possible in each passage of Flash medium 11 that the utility model is pressed boot sequence with log-on data, and then improve the efficient that reads in advance, further reduces the start-up time of system whereby.
Fig. 6 is the system start method process flow diagram based on solid state hard disc of the utility model one embodiment, and it is through realizing that like Fig. 2 or system 100 shown in Figure 3 this method comprises:
Step S601, when system 100 starts for the first time, the log-on data that log-on data processing module 13 record main frames 20 read from solid state hard disc 10.The log-on data of system 100 is stored in the Flash medium 11 of solid state hard disc 10; And each data has a LPA; It is corresponding to the physical address of Flash medium 11; When system 100 started, also work the simultaneously LPA of opening entry log-on data of record sub module 131 read end until log-on data.
Step S602, after system 100 started, read module 14 received preparatory reading order in advance, and in the free time of solid state hard disc 10 log-on data in the Flash medium 11 is sent to DRAM buffer memory 12.Among the embodiment of the utility model, the free time of solid state hard disc 10 comprises: the free time behind solid state hard disc 10 power-up initializings, and main frame 20 from DRAM buffer memory 12 reading of data to main frame 20 once more from time of DRAM buffer memory 12 reading of data.
Fig. 7 is the process flow diagram that the log-on data of the utility model one embodiment is handled, and it comprises:
Step S701, system's 100 electrifying startups, solid state hard disc 10 beginning initialization.After solid state hard disc 10 was accomplished initialization, because BIOS does not also scan solid state hard disc 10, it was in idle condition.
Step S702, system 100 starts the entering hard disk vectoring phase, begins to prepare visit solid state hard disc 10.
Step S703; Solid state hard disc 10 receives the log-on data of being sent by main frame 20 and handles sign on; Record sub module 131 record is from main frame 20 visit solid state hard discs 10 needed log-on datas this moment; Just write down the logical page address LPA of solid state hard disc 10, this logical page address is corresponding one by one with Flash medium physical page address.
Step S704, system 100 starts completion, and solid state hard disc 10 receives the log-on data of being sent by main frame 20 and handles halt instruction, and record sub module stops to write down logical page address LPA.
Step S705, arrangement submodule 132 will write down log-on data and be arranged in uniformly on each passage of Flash medium 11 by boot sequence.
Fig. 8 is the process flow diagram that reads in advance of the utility model one embodiment, and it comprises:
Step S801, system's 100 electrifying startups, solid state hard disc 10 beginning initialization.After solid state hard disc 10 was accomplished initialization, because BIOS does not also scan solid state hard disc 10, it was in idle condition.
Step S802, read module 14 receives preparatory reading command in advance, and the log-on data in the Flash medium 11 is read in the DRAM buffer memory 12.
Step S803, system 100 gets into the hard disk vectoring phase, and main frame 20 reads log-on data from DRAM buffer memory 12.
Step S804, when main frame 20 began to read the data of DRAM buffer memory 12, in advance read module 14, read until log-on data and to finish to the DRAM buffer memory from Flash medium 11 reading section system start-up data.
In sum; Record needed the hard disc data of startup when the utility model started in the solid state hard disc system through the log-on data processing module is set for the first time; Preparatory read module is set simultaneously; Make solid state hard disc when starting, can receive preparatory reading order next time, the log-on data in its Flash medium is sent to the DRAM buffer memory in the free time of solid state hard disc in system.The free time that makes full use of solid state hard disc is whereby improved data read rates.Better, solid state hard disc can also be evenly distributed on each passage of its Flash medium with log-on data in advance, and the efficient that further whereby raising is read in advance reduces the system start-up time.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
