Description
Technical field
The present invention relates to a kind of computer architecture of quick startup computer applied algorithm, relate in particular to a kind of computer architecture that utilizes Installed System Memory to reach quick startup computer applied algorithm as getting storage space soon.
Background technology
In a computer system, the quality of system executive efficiency, main key are on the CPU (central processing unit) (CPU).And the performance performance of performance CPU (central processing unit) is except outside the Pass the arithmetic speed with itself has, and the order and the frequency range that also are subjected to carrying out with CPU (central processing unit) data transfer are relevant.This is because in known computer architecture, and CPU (central processing unit) is carried out reading of data to different storage devices in a certain order, and this CPU (central processing unit) is also inequality with the data transfer frequency range between different storage device.Therefore, when a computer system desire was carried out an application program, this central processing unit will be found out from different storage devices in regular turn and carry out the required data of this application program, just can carry out the executive routine of this application program.Therefore, how to promote the execution usefulness of computing machine, except the arithmetic speed that must consider CPU (central processing unit), also must consider the speed of data read between the storage device of CPU (central processing unit) and collocation simultaneously, could effectively improve the execution usefulness of computing machine.
As shown in Figure 1, it illustrates that known a kind of CPU (central processing unit) carries out the process flow diagram of data read.At first, in the step 201, this CPU (central processing unit) desire is carried out an application program and is begun to carry out the program of reading of data.Then, in the step 202, this CPU (central processing unit) is from immediate memory storage, promptly searches the data of carrying out this application program institute palpus in the L1/L2 high-speed cache, if when the data of institute palpus can find from the L1/L2 high-speed cache, then these data are read from this L1/L2 high-speed cache; If can't obtain enough data from the L1/L2 high-speed cache, then this CPU (central processing unit) promptly enters the needed data of the middle search of memory storage (as Installed System Memory) of next stage.Then, in the step 203, this CPU (central processing unit) judges whether to obtain the data that all need from Installed System Memory, if can, then these data are read, if not all right, then enter in the memory storage of next stage needed data read come out (shown in step 204) again.The memory storage of afterbody is a hard disk unit usually, and it is because of having enough capacity, thus can store desire all related datas of executive utility.In other embodiments, the memory storage of afterbody also may be diskette unit, CD-ROM drive or other storage device etc.
Though hard disk unit has bigger storage volume, yet utilize mechanical action (read head reads the magnetic Storage Media) to carry out, thereby its reading speed is confined to the grade of millisecond (1/1000 second) more because read the acts may of hard disk unit data; And the acts may that reads of L1/L2 high-speed cache or Installed System Memory sees through to discharge and recharge and carries out, thereby its data search or only must just can finishing in the grade of microsecond (1/1000000 second) several times of reading.Therefore, when a computer system starting one application program, when if CPU (central processing unit) reads the data of institute's palpus as the data read flow process of Fig. 1 as described above from L1/L2 high-speed cache or Installed System Memory, system must expend many times in search and the access of waiting for hard disk unit execution data, thereby causes the execution usefulness of whole computer system significantly to reduce.
In order to address the above problem, the applicant once proposed " a kind of computing machine fast starting method and device " in the TaiWan, China patent application case 93100271 on January 6th, 1993, it is used as the startup disk driver by a random access memory, storing a large amount of start data, and reach the purpose of quick turn-on.Yet with the operating system of generally using now, for example Windows XP is an example, if want to load the data that a whole set of operating system need store hundreds of megabyte (Mega Bytes) at least in random access memory.Therefore, though above-mentioned method can effectively be reached the purpose of quick turn-on, yet, on cost consideration, just can reach required purpose owing to need in computer system, additionally to buy more a cover " random access memory disk (RAMDISK) ", so said method there is the restriction on its cost.
