Description
本發明有關於電腦之技術領域,特別有關於一種快速開機之電腦系統及方法、電腦可讀取之記錄媒體及電腦程式產品。 The invention relates to the technical field of computers, in particular to a computer system and method for quickly starting up, a computer readable recording medium and a computer program product.
當電腦的電源開啟,中央處理單元(CPU)執行主機板上的快閃記憶體(flash memory)中之基本輸入輸出系統(Basic Input Output System,BIOS),並將晶片組和記憶體子系統初始化。CPU會將BIOS從快閃記憶體中解壓縮到系統的主記憶體,並且開始執行系統初始化及系統診斷等功能。 When the power of the computer is turned on, the central processing unit (CPU) executes the basic input output system (BIOS) in the flash memory on the motherboard, and initializes the chipset and the memory subsystem. . The CPU will decompress the BIOS from the flash memory to the main memory of the system and start performing functions such as system initialization and system diagnostics.
BIOS與硬體系統係整合在一起(將BIOS程式指令燒錄在IC中),早期BIOS是儲存在ROM(唯讀記憶體)中而無法被修改。因為BIOS的大小和複雜程度隨時間不斷增加,而且硬體的更新速度加快,令BIOS也必須不斷更新以支援新硬體,於是BIOS就改為儲存在EEPROM,讓使用者可以輕易更新BIOS。 The BIOS is integrated with the hardware system (burning BIOS program instructions in the IC), and the early BIOS is stored in ROM (read-only memory) and cannot be modified. Because the size and complexity of the BIOS increase over time, and the hardware update speed is accelerated, the BIOS must be constantly updated to support the new hardware, so the BIOS is stored in the EEPROM, so that users can easily update the BIOS.
然而在開機時,CPU存取在EEPROM中的BIOS之速度會比較慢,造成開機時間變長,而且EEPROM的容量較小及價格較高,因此增加硬體設備的成本。 However, at boot time, the CPU accesses the BIOS in the EEPROM at a slower rate, resulting in longer boot times, and a smaller EEPROM capacity and higher price, thus increasing the cost of the hardware device.

為使熟習本發明所屬技術領域之一般技藝者能更進一步了解本發明,下文特列舉本發明之較佳實施例,並配合所附圖式,詳細說明本發明的構成內容及所欲達成之功效。 The present invention will be further understood by those of ordinary skill in the art to which the present invention pertains. .
圖1為本發明第一實施例之電腦系統之示意方塊圖。在第一實施例中,電腦系統10包括一CPU(中央處理單元)12及一系統記憶體14。系統記憶體14之一區塊存放有一BIOS 16,其中,系統記憶體14存放BIOS 16之區塊為一非揮發性記憶體。 1 is a schematic block diagram of a computer system according to a first embodiment of the present invention. In the first embodiment, computer system 10 includes a CPU (Central Processing Unit) 12 and a system memory 14. One block of the system memory 14 stores a BIOS 16, wherein the system memory 14 stores the block of the BIOS 16 as a non-volatile memory.
當電腦系統10執行開機程序時,透由硬體初始化系統記憶體14,在初始化系統記憶體14後,CPU 12可存取在系統記憶體中14之BIOS 16的程式碼,並由CPU 12執行BIOS 16的程式碼以進行電腦系統10之開機程序。 When the computer system 10 executes the booting process, the system memory 14 is initialized by the hardware. After the system memory 14 is initialized, the CPU 12 can access the BIOS 16 code in the system memory 14 and is executed by the CPU 12. The BIOS 16 code is used to boot the computer system 10.
圖2為本發明第二實施例之電腦系統之示意方塊圖。在第二實施例中,電腦系統10除了包括CPU 12及系統記憶體14之外,還包括一獨立電池18。可為隨機存取記憶體(RAM)之系統記憶體14之一區塊存放有一BIOS 16,而獨立電池18供應電源給系統記憶體14。 2 is a schematic block diagram of a computer system in accordance with a second embodiment of the present invention. In the second embodiment, computer system 10 includes a separate battery 18 in addition to CPU 12 and system memory 14. A BIOS 16 can be stored in one of the system memory 14 of the random access memory (RAM) and the independent battery 18 supplies power to the system memory 14.
電腦系統10在關機狀態時,獨立電池18供電給系統記 憶體14,因此存放在系統記憶體14中之BIOS 16之程式碼並不會因電腦系統10關機而遺失。當電腦系統10執行開機程序時,透由硬體初始化系統記憶體14,在初始化系統記憶體14後,CPU 12可存取在系統記憶體中14之BIOS 16的程式碼,並由CPU 12執行BIOS 16的程式碼以進行電腦系統10之開機程序。 When the computer system 10 is in the off state, the independent battery 18 supplies power to the system. The memory 14 is stored, so that the BIOS 16 code stored in the system memory 14 is not lost due to the shutdown of the computer system 10. When the computer system 10 executes the booting process, the system memory 14 is initialized by the hardware. After the system memory 14 is initialized, the CPU 12 can access the BIOS 16 code in the system memory 14 and is executed by the CPU 12. The BIOS 16 code is used to boot the computer system 10.
圖3為本發明第三實施例之電腦系統之示意方塊圖。在第三實施例中,電腦系統10除了包括CPU 12及系統記憶體14之外,還包括一電源管理模組20。可為RAM之系統記憶體14之一區塊存放有一BIOS 16,而電源管理模組20在電腦系統10關機狀態後可供應電源給系統記憶體14。 3 is a schematic block diagram of a computer system in accordance with a third embodiment of the present invention. In the third embodiment, the computer system 10 includes a power management module 20 in addition to the CPU 12 and the system memory 14. A BIOS 16 can be stored in a block of the system memory 14 of the RAM, and the power management module 20 can supply power to the system memory 14 after the computer system 10 is powered off.
電腦系統10在關機狀態時,電源管理模組20執行一記憶體喚醒(Suspend to RAM)之程序,因此存放在系統記憶體14中之BIOS 16之程式碼並不會因電腦系統10關機而遺失。當電腦系統10執行開機程序時,透由硬體初始化系統記憶體14,在初始化系統記憶體14後,CPU 12可存取在系統記憶體中14之BIOS 16的程式碼,並由CPU 12執行BIOS 16的程式碼以進行電腦系統10之開機程序。 When the computer system 10 is in the off state, the power management module 20 executes a program of Suspend to RAM, so the code of the BIOS 16 stored in the system memory 14 is not lost due to the shutdown of the computer system 10. . When the computer system 10 executes the booting process, the system memory 14 is initialized by the hardware. After the system memory 14 is initialized, the CPU 12 can access the BIOS 16 code in the system memory 14 and is executed by the CPU 12. The BIOS 16 code is used to boot the computer system 10.
Suspend to RAM(記憶體喚醒)狀態簡稱STR。顧名思義,STR就是把電腦系統進入STR前的工作狀態資料都存放到系統記憶體中。在STR狀態下,電源仍然繼續為系統記憶體等最必要的設備供電,以確保資料不遺失,而其他設備均處於關閉狀態,電腦系統的耗電量極低。一旦按下Power按鈕(主機電源開關),電腦系統就被喚醒,馬上從系統記憶體中讀取資料並恢復到STR之前的工作狀態。系統記憶體的讀寫速度極快,因此進入和離開STR狀態所花費的時間不過是幾秒鐘而已。 The Suspend to RAM status is referred to as STR. As the name suggests, STR is to store the working state data of the computer system before entering the STR into the system memory. In the STR state, the power supply continues to supply power to the most necessary devices such as system memory to ensure that data is not lost, while other devices are turned off, and the power consumption of the computer system is extremely low. Once the Power button (host power switch) is pressed, the computer system is woken up and immediately reads data from the system memory and resumes the working state before the STR. System memory reads and writes very fast, so the time it takes to enter and leave the STR state is only a few seconds.
圖4為本發明第一實施例之電腦系統之快速開機方法之流程圖。在第一實施例中,電腦系統10處在關機狀態時,獨立電池18供電給系統記憶體14(步驟S22)。當按下Power按鈕時,電腦系統10開始執行開機程序,並透由硬體初始化系統記憶體14(步驟S30)。接著,由CPU 12存取在系統記憶體14中之BOOS 16的程式碼(步驟S32)。然後,由CPU 12執行BIOS 16的程式碼,以進行電腦系統10之開機程序(步驟S34)。 4 is a flow chart of a method for quickly booting a computer system according to a first embodiment of the present invention. In the first embodiment, when the computer system 10 is in the off state, the independent battery 18 supplies power to the system memory 14 (step S22). When the Power button is pressed, the computer system 10 starts the booting process and initializes the system memory 14 by hardware (step S30). Next, the CPU 12 accesses the code of the BOOS 16 in the system memory 14 (step S32). Then, the program code of the BIOS 16 is executed by the CPU 12 to perform the booting process of the computer system 10 (step S34).
由於電腦系統10在關機狀態時,電腦系統10之獨立電池18會供電給系統記憶體12,如此在電腦系統10關機時在系統記憶體14中之BIOS 16不會遺失,如圖2所示。 Since the computer system 10 is in the off state, the independent battery 18 of the computer system 10 will supply power to the system memory 12, so that the BIOS 16 in the system memory 14 will not be lost when the computer system 10 is turned off, as shown in FIG.
圖5為本發明第二實施例之電腦系統之快速開機方法之流程圖。在第二實施例中,預存BIOS 16於系統記憶體14為一非揮發性記憶體之區塊中(步驟S24)。在第二實施例中之其餘步驟與第一實施例中之步驟S30、S32、S34相同,在此省略說明。 FIG. 5 is a flowchart of a method for quickly starting up a computer system according to a second embodiment of the present invention. In the second embodiment, the pre-stored BIOS 16 is in the block of the non-volatile memory in the system memory 14 (step S24). The remaining steps in the second embodiment are the same as steps S30, S32, and S34 in the first embodiment, and the description thereof is omitted here.
由於系統記憶體14存放BIOS 16之區塊為非揮發性記憶體,如此在電腦系統10關機時在系統記憶體14中之BIOS 16不會遺失,如圖1所示。 Since the system memory 14 stores the blocks of the BIOS 16 as non-volatile memory, the BIOS 16 in the system memory 14 will not be lost when the computer system 10 is turned off, as shown in FIG.
圖6為本發明第三實施例之電腦系統之快速開機方法之流程圖。在第三實施例中,系統記憶體10在關機狀態時,由電腦系統10之一電源管理模組20供電給系統記憶體14(步驟S26)。在第三實施例中之其餘步驟與第一實施例中之步驟S30、S32、S34相同,在此省略說明。 FIG. 6 is a flowchart of a method for quickly starting up a computer system according to a third embodiment of the present invention. In the third embodiment, when the system memory 10 is in the off state, power is supplied from the power management module 20 of the computer system 10 to the system memory 14 (step S26). The remaining steps in the third embodiment are the same as steps S30, S32, and S34 in the first embodiment, and the description is omitted here.
由於在電腦系統10關機時電源管理模組20執行記憶體喚醒之程序,電源管理模組20供電給系統記憶體14,如此在電腦系統 10關機狀態時在系統記憶體14中之BIOS 16不會遺失,如圖3所示。 Since the power management module 20 executes the memory wake-up procedure when the computer system 10 is powered off, the power management module 20 supplies power to the system memory 14, thus in the computer system. When the BIOS is turned off, the BIOS 16 in the system memory 14 is not lost, as shown in FIG.
