圖1係本發明電子設備100一實施方式之模組圖。在本實施方式中，電子設備100可記錄其使用時間，其包括快閃記憶體(Flash memory)200、隨機存取記憶體(Random Access Memory)300、設定模組110、複製模組120、記錄模組130及寫入模組140。其中，隨機存取記憶體300用於儲存當前正在運行之資料。1 is a block diagram of an embodiment of an electronic device 100 of the present invention. In this embodiment, the electronic device 100 can record the usage time thereof, and includes a flash memory 200, a random access memory 300, a setting module 110, a copy module 120, and a record. Module 130 and write module 140. The random access memory 300 is used to store the currently running data.
快閃記憶體200用於儲存表徵使用時間的位元。在本實施方式中，快閃記憶體200從其儲存空間中劃分了一個固定大小的區塊，如64Kbits，用於儲存表徵使用時間的位元。The flash memory 200 is used to store bits characterizing the time of use. In the present embodiment, the flash memory 200 divides a fixed size block, such as 64 Kbits, from its storage space for storing bits characterizing the usage time.
設定模組110用於將快閃記憶體200中表徵使用時間的位元初始化為第一值，以及設定電子設備100於使用期間覆寫快閃記憶體200中表徵使用時間的位元之時間間隔。在本實施方式中，該第一值為1。The setting module 110 is configured to initialize a bit characterizing the usage time in the flash memory 200 to a first value, and set a time interval during which the electronic device 100 overwrites the bit characterizing the usage time in the flash memory 200 during use. . In the present embodiment, the first value is 1.
複製模組120用於在電子設備100每次開機使用時將快閃記憶體200中表徵使用時間的位元複製到隨機存取記憶體300。The copy module 120 is configured to copy the bits representing the usage time in the flash memory 200 to the random access memory 300 each time the electronic device 100 is powered on.
記錄模組130用於在隨機存取記憶體300中表徵使用時間的位元中找尋第一個為第一值的位元並將其索引值記錄於變數n中，其中每當時間間隔到達時記錄模組130將隨機存取記憶體300中變數n對應之位元覆寫為第二值，並將該變數n加1。其中被覆寫為第二值之位元用於表徵新增使用時間。在本實施方式中，第二值為0。The recording module 130 is configured to find the first bit with the first value in the bit characterizing the usage time in the random access memory 300 and record the index value in the variable n, where the time interval arrives. The recording module 130 overwrites the bit corresponding to the variable n in the random access memory 300 to the second value, and increments the variable n by one. The bit that is overwritten with the second value is used to characterize the new usage time. In the present embodiment, the second value is zero.
寫入模組140用於判斷當前隨機存取記憶體300中表徵使用時間的位元是否超過快閃記憶體200所能記錄的最大使用時間，並在當前隨機存取記憶體300中表徵使用時間的位元未超過快閃記憶體200所能記錄的最大使用時間時將隨機存取記憶體300中表徵新增使用時間的位元寫入快閃記憶體200。在本實施方式中，快閃記憶體200從其儲存空間中劃分了一個固定大小的區塊來儲存表徵使用時間的位元。快閃記憶體200所能記錄的最大使用時間等於該固定大小的區塊所能記錄的最大值。The write module 140 is configured to determine whether the bit in the current random access memory 300 characterizing the usage time exceeds the maximum usage time that the flash memory 200 can record, and characterize the use time in the current random access memory 300. The bit characterizing the new usage time in the random access memory 300 is written to the flash memory 200 when the bit does not exceed the maximum usage time that can be recorded by the flash memory 200. In the present embodiment, the flash memory 200 divides a block of a fixed size from its storage space to store bits characterizing the time of use. The maximum usage time that the flash memory 200 can record is equal to the maximum value that can be recorded by the fixed size block.
圖2係本發明電子設備100記錄使用時間一實施方式之示意圖。在本實施方式中，當廠商出售電子設備100至用戶時，可以利用設定模組110將快閃記憶體200中表徵使用時間的位元全部初始化為1。2 is a schematic diagram of an embodiment of the electronic device 100 of the present invention recording usage time. In the present embodiment, when the manufacturer sells the electronic device 100 to the user, the setting module 110 can be used to initialize all the bits in the flash memory 200 that characterize the usage time to 1.
當用戶首次使用電子設備100時，複製模組120將快閃記憶體200中表徵使用時間的位元複製到隨機存取記憶體300，設定模組110設定電子設備100使用期間覆寫快閃記憶體200中表徵使用時間的位元之時間間隔為1分鐘，記錄模組130在隨機存取記憶體300中表徵使用時間的位元中找尋第一個為1的位元並將其索引值記錄於變數n中。由於電子設備100是首次使用，所以隨機存取記憶體300中表徵使用時間的位元中表徵使用時間的位元初始值全部為1，其中第一個為1的位元的索引值即為1，故變數n等於1。When the user first uses the electronic device 100, the copy module 120 copies the bits representing the usage time in the flash memory 200 to the random access memory 300, and the setting module 110 sets the flash memory to be overwritten during use of the electronic device 100. The time interval of the bit characterization time of the body 200 is 1 minute, and the recording module 130 finds the first bit of 1 in the bit characterizing the use time in the random access memory 300 and records the index value thereof. In the variable n. Since the electronic device 100 is used for the first time, the initial values of the bits characterizing the usage time in the bits characterizing the usage time in the random access memory 300 are all 1, wherein the index value of the first bit of 1 is 1 Therefore, the variable n is equal to 1.
當1分鐘的時間間隔到達時(即使用1分鐘後)，記錄模組130將隨機存取記憶體300中變數n為1所對應之位元覆寫為0，並將該變數n加1。換言之，記錄模組130將隨機存取記憶體300中第一個為1的位元覆寫為0，並將變數n加1成為2。其中被覆寫為0之位元用於表徵新增使用時間。When the 1-minute time interval is reached (i.e., after 1 minute of use), the recording module 130 overwrites the bit corresponding to the variable n of 1 in the random access memory 300 to 0, and increments the variable n by one. In other words, the recording module 130 overwrites the first bit of the random access memory 300 with 1 as 0, and increments the variable n by 1. The bit that is overwritten with 0 is used to characterize the new usage time.
此時，寫入模組140判斷當前隨機存取記憶體300中表徵使用時間的位元是否超過快閃記憶體200所能記錄的最大使用時間。若當前隨機存取記憶體300中表徵使用時間的位元未超過快閃記憶體200所能記錄的最大使用時間時，則寫入模組140僅將隨機存取記憶體300中表徵新增使用時間的位元寫入快閃記憶體200。換言之，寫入模組140僅將隨機存取記憶體300中被覆寫為0的位元寫入快閃記憶體200。如圖2所示，此時快閃記憶體200中表徵使用時間的位元中第一個位元為0，其他位元均為1。At this time, the writing module 140 determines whether the bit characterizing the usage time in the current random access memory 300 exceeds the maximum usage time that the flash memory 200 can record. If the bit characterizing the usage time in the current random access memory 300 does not exceed the maximum usage time that the flash memory 200 can record, the write module 140 only adds the representation in the random access memory 300. The bits of time are written to the flash memory 200. In other words, the write module 140 writes only the bits of the random access memory 300 that are written as 0 to the flash memory 200. As shown in FIG. 2, at this time, the first bit in the bit characterizing the usage time in the flash memory 200 is 0, and the other bits are all 1.
當1分鐘的時間間隔再次到達時(即使用2分鐘後)，記錄模組130將隨機存取記憶體300中變數n為2所對應之位元覆寫為0，並將該變數n加1。在本實施例中，記錄模組130將隨機存取記憶體300中第二個為1的位元覆寫為0，並將變數n加1成為3。其中被覆寫為0之位元亦用於表徵新增使用時間。When the time interval of 1 minute arrives again (that is, after 2 minutes of use), the recording module 130 overwrites the bit corresponding to the variable n of 2 in the random access memory 300 to 0, and adds 1 to the variable n. . In the present embodiment, the recording module 130 overwrites the second bit of the random access memory 300 with 1 as 0, and increments the variable n by 1. The bit that is written as 0 is also used to characterize the new usage time.
此時，寫入模組140判斷當前隨機存取記憶體300中表徵使用時間的位元是否超過快閃記憶體200所能記錄的最大使用時間。若當前隨機存取記憶體300中表徵使用時間的位元未超過快閃記憶體200所能記錄的最大使用時間時，則寫入模組140僅將隨機存取記憶體300中表徵新增使用時間的位元寫入快閃記憶體200。換言之，寫入模組140僅將隨機存取記憶體300中被覆寫為0的位元寫入快閃記憶體。如圖2所示，此時快閃記憶體200中表徵使用時間的位元中第一個與第二個位元為0，其他位元均為1。At this time, the writing module 140 determines whether the bit characterizing the usage time in the current random access memory 300 exceeds the maximum usage time that the flash memory 200 can record. If the bit characterizing the usage time in the current random access memory 300 does not exceed the maximum usage time that the flash memory 200 can record, the write module 140 only adds the representation in the random access memory 300. The bits of time are written to the flash memory 200. In other words, the write module 140 writes only the bits in the random access memory 300 that are written as 0 to the flash memory. As shown in FIG. 2, at this time, the first and second bits in the bits representing the usage time in the flash memory 200 are 0, and the other bits are all 1.
以此類推，當使用n分鐘後，快閃記憶體200中表徵使用時間的位元中第一個至第n個位元為0，其他位元均為1。By analogy, after n minutes of use, the first to nth bits in the bits characterizing the usage time in the flash memory 200 are 0, and all other bits are 1.
因此，快閃記憶體200中表徵使用時間的位元可靠地記錄了電子設備100之使用時間，避免電子設備100的廠商與用戶之間的消費糾紛。Therefore, the bits characterizing the usage time in the flash memory 200 reliably record the usage time of the electronic device 100, avoiding consumption disputes between the manufacturer and the user of the electronic device 100.
圖3係本發明電子設備100記錄使用時間之方法一實施方式之流程圖。在本實施方式中，電子設備100記錄使用時間之方法藉由圖1中的功能模組來實施。FIG. 3 is a flow chart of an embodiment of a method for recording usage time of the electronic device 100 of the present invention. In the present embodiment, the method of recording the usage time of the electronic device 100 is implemented by the function module in FIG. 1.
在步驟S300，設定模組110將快閃記憶體200中表徵使用時間的位元初始化為第一值。在本實施方式中，第一值為1。In step S300, the setting module 110 initializes the bit characterizing the usage time in the flash memory 200 to the first value. In the present embodiment, the first value is 1.
在步驟S302，複製模組120在電子設備100開機使用時將快閃記憶體200中表徵使用時間的位元複製到隨機存取記憶體300。In step S302, the copy module 120 copies the bits representing the usage time in the flash memory 200 to the random access memory 300 when the electronic device 100 is powered on.
在步驟S304，記錄模組130在隨機存取記憶體300中表徵使用時間的位元中找尋第一個為第一值的位元並將其索引值記錄於變數n中。In step S304, the recording module 130 finds the first bit in the random access memory 300 that is the first value in the bit time of use and records its index value in the variable n.
在步驟S306，設定模組110設定電子設備100使用期間覆寫快閃記憶體200中表徵使用時間的位元之時間間隔。In step S306, the setting module 110 sets a time interval during which the electronic device 100 overwrites the bit in the flash memory 200 that characterizes the usage time.
在步驟S308，每當時間間隔到達時記錄模組130將隨機存取記憶體300中變數n對應之位元覆寫為第二值，並將該變數n加1。其中被覆寫為第二值之位元用於表徵新增使用時間。在本實施方式中，第二值為0。In step S308, the recording module 130 overwrites the bit corresponding to the variable n in the random access memory 300 to the second value every time the time interval arrives, and increments the variable n by one. The bit that is overwritten with the second value is used to characterize the new usage time. In the present embodiment, the second value is zero.
在步驟S310，寫入模組140判斷當前隨機存取記憶體300中表徵使用時間的位元是否超過快閃記憶體200所能記錄的最大使用時間。在本實施方式中，快閃記憶體200從其儲存空間中劃分了一個固定大小的區塊來儲存表徵使用時間的位元，快閃記憶體200所能記錄的最大使用時間等於該固定大小的區塊所能記錄的最大值。In step S310, the writing module 140 determines whether the bit in the current random access memory 300 characterizing the usage time exceeds the maximum usage time that the flash memory 200 can record. In this embodiment, the flash memory 200 divides a fixed-size block from its storage space to store a bit characterizing the usage time, and the maximum usage time that the flash memory 200 can record is equal to the fixed size. The maximum value that can be recorded by the block.
若當前隨機存取記憶體300中表徵使用時間的位元未超過快閃記憶體200所能記錄的最大使用時間，則在步驟S312，寫入模組140將隨機存取記憶體300中表徵新增使用時間的位元寫入快閃記憶體200。If the bit characterizing the usage time in the current random access memory 300 does not exceed the maximum usage time that the flash memory 200 can record, then in step S312, the write module 140 will characterize the new in the random access memory 300. The bits of the increased usage time are written to the flash memory 200.
上述步驟S308-S312在電子設備100使用期間循環執行，直到電子設備100關機或當前隨機存取記憶體300中表徵使用時間的位元超過快閃記憶體200所能記錄的最大使用時間為止。The above steps S308-S312 are cyclically executed during use of the electronic device 100 until the electronic device 100 is turned off or the bit in the current random access memory 300 characterizing the usage time exceeds the maximum usage time that the flash memory 200 can record.
在本發明實施方式中，由於寫入模組140僅將隨機存取記憶體300中表徵新增使用時間的位元寫入快閃記憶體200，亦即，僅對快閃記憶體200做寫入的動作，不做抹除，從而可以避免在抹除時電子設備100斷電造成資料錯誤。另外，複製模組120與寫入模組140皆是以位元為單位對快閃記憶體200進行複製與寫入，從而節省快閃記憶體200的使用空間。In the embodiment of the present invention, since the write module 140 only writes the bit in the random access memory 300 that represents the newly used time to the flash memory 200, that is, only writes to the flash memory 200. The incoming action is not erased, so that the electronic device 100 can be prevented from being powered off due to data loss during erasing. In addition, both the copy module 120 and the write module 140 copy and write the flash memory 200 in units of bits, thereby saving the use space of the flash memory 200.
綜上所述，本發明符合發明專利要件，爰依法提出專利申請。惟，以上所述者僅為本發明之較佳實施例，舉凡熟悉本案技藝之人士，在爰依本案發明精神所作之等效修飾或變化，皆應包含於以下之申請專利範圍內。In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
