Embodiment Construction

[0024] The method for processing disk array commands according to a preferred embodiment of the present invention will be described below with reference to related figures, wherein the same elements will be described with the same reference symbols.

[0025] Please refer to figure 1 As shown, it should first be explained that a system 1 used in conjunction with the disk array command processing method of the preferred embodiment of the present invention has a central processing unit 11 , a memory module 12 and a controller 13 . In this embodiment, when the system 1 is in a system loading period (OSloading period) or a power management period (power management period), the memory module 12 has an available memory 121 .

[0026] When the system 1 is running at the system loading stage, the available memory 121 may be a part of the ROM, and the capacity of the ROM is 640K bytes. Please refer again figure 2 As shown, when the system 1 is in the power management stage, the avail...

Abstract

The method is executed when capacity of an available memory in a system is less than size of an instruction. The method includes following steps: first, the instruction is cut into multiple pieces of cutting instruction; then, multiple pieces of cutting instruction are transferred to memory according to sequence; finally, a controller executes multiple pieces of cutting instruction according to sequence.

Description

technical field [0001] The invention relates to a command processing method, in particular to a disk array command processing method. Background technique [0002] Hard disks are one of the most commonly used storage devices since the advent of personal computers. However, in the entire computer system architecture, compared with the central processing unit (CPU) and random access memory (RAM), the access speed of the hard disk is one of the slowest key points in the computer. Moreover, due to the extensive use of servers and the demand for large-capacity, high-speed storage devices for professional audio-visual, in order to speed up the overall data flow of the computer and improve processing performance, the Disk Array (RedundantArrays of Inexpensive Disks, RAID) system has recently become a popular choice for users. The best choice for storage devices. [0003] A disk array simulates a logical hard disk in the system by more than two hard disks, and uses the disk array ...
