The arm is a hierarchical structure. The movement of data from memory to CPU can only be completed through the L/s command, that is, the LDR/STR command.For example, to read data from somewhere in the memory to a register, you can only use LDRFor example:LDR r0, 0x12345678Store the value in 0x12345678 to R0.But mov cannot do this job. mov can only move data between registers, or move the immediate number to

Reprinted http://student.csdn.net/space.php? Uid = 111047 Do = Blog id = 14341 In the arm instruction set, LDR is usually used as the loading command, but it can also be used as a pseudo command.Beginners generally do not notice their differences. In fact, these two commands are very common during embedded development! We should understand their differences. The form of the LDR pseudo command is "ldr rn, = expr ". It is installed in a 32bit constant and an address to the Register.The followin

Memory card backup may be due to the computer power off, the display can not read to unplug the display needs to be formatted, after self-use on-line data recovery software to try to reply, most of the pictures have been restored, but the video can not play, telephoto video for MP4 format non-mov before the bar also asked, said the need to do debris level repair, Is that so?With the development of science and technology, more and more friends are enco

ARM is a RISC structure, the movement of data from memory to CPU can only be done by l/s instruction, that is, ldr/str instruction.For example, if you want to read data from somewhere in memory to a register, you can only use LDRLike what:Ldr R0, 0x12345678is to store the value of the 0x12345678 address in the r0.And MOV can not do this job, MOV can only move data between registers, or to move the number of

Typical Pentium software delay loops can be written using mov and loop instructions.For example, the following instruction sequence can be used for a delay loop: mov CX, countdelay: loop delayThe initial loop counter value of "Count" can be calculated using the cycles required to execute the following Pentium instructions: mov REG/Imm (1 cycle) loop label (5/6 cy

I was fooled and thought that Lea and mov commands are similar. Today I knoW it. By the way, I tested the efficiency of C inline assembly. Discussion on mov (command group) and Lea commands Quotes from kanxue:Lea eax, [EBX + 4] is equivalent to: eax = EBX + 4. The LEA command allows you to complete computation within a clock, which is fast.Add EBX, 4; equivalent to EBX = EBX + 4DifferentMoV eax and EBX +

MoV PC, R4 @ call kernel is definitely redirected to R4: 40008000 to start execution Start to enter the image. The image is generated by vmlinux. Therefore, read and understand the image from vmlinux. ARCH/Unicore/kernel directory. According to its link script, start from head. S: _ Lookup_processor_type: Compare proc_info_list with processor by using relative fetch address (because an image supports one processor, the processor information is retriev

The idea is to first obtain the file type and select different webpage player codes according to the type .. 3, 5, go, 2 ..... at the same time, in order to reuse the code in the future, a general call function is written. facilitate future calls in other systems .. The source code is as follows: Copy codeThe Code is as follows: Sub SelPlay (strUrl, strWidth, StrHeight) Dim Exts, isExt If strUrl IsExt = LCase (Mid (strUrl, limit Rev (strUrl, ".") + 1 )) Else IsExt = "" End If Exts = "avi, wmv, a

interpret theatom's data. use the atom's size field to skip this atom and all of its contents. this allows adegree of forward compatability with extensions to the QuickTime file format. 3. Extended size If the size field of an atom is set to 1, the Type field is followed by a 64-bit extended size Field, which contains the actual size of the atom as a 64-bit unsigned integer. This is used whenthe size of a media data atom exceeds 2 ^ 32 bytes. 4. Version All version fields must be set to0, u

, and the result overwrites the order in reverse order. This function returns the result of the target range. The first element to be overwritten is displayed in sequence (that is, the first element to be overwritten rather than the first element to be overwritten) (See the following example ). The behavior is similar: templateA simple example: #include Run: Note that the returned result is an iterator pointing to the 99 element in the result, instead of the first element in the last range!

Lin Yu also no guest atmosphere, will dan all income ring space, hand only left on behalf of He Jiace Qing's token, this token with Longchamp leather folder before also went out of the same, the token there is a word, but the color is different, it is estimated that this is the region.Brother, let's go, the channel is open.

In the past few days, the SQL server data compression function has been tested. By enabling compression for Data Warehouse tables, the disk space is greatly reduced, and query performance and backup speed are improved. However, the data compression function of SQL Server is available only for the Enterprise Edition. The Standard Edition cannot be used. After checking through the Internet, Rea hat provides a similar tool, SQL storage compress, and cla

Cold Compress Therapy Cold Compress can reduce the subcutaneous capillary contraction and blood flow, reduce local congestion, inhibit the sensory function of nerve cells, reduce the pain, with cooling, damage control, pain relief, prevent secondary infection and increase of hematoma and so on. There are two common cold compress treatments: (1) ice bag p

SyntaxCompress [-dfvcV] [-B maxbits] [file...]Parameters: C output result to standard output device (usually screen) F. Write the file forcibly. If the target file already exists, it will be overwritten (force) V prints program execution messages on the screen (verbose) B sets the upper limit of the number of common strings. It is calculated in bits and can be set to 9 to 16 bits. Because the larger the value, the more common strings can be used and the larger the compression ratio,

Rea Hat provides a similar tool, SQL Storage Compress, and claims to be able to achieve a compression ratio of 90%. SQL Storage Compress provides a 14-day version. After being downloaded, The HyperBac Control Service is started. This service is used with Windows I/O Manager to compress or decompress SQL Server read/write requests, without affecting SQL Server use

When I was bored, I wrote When viewstate is not stored to the database When storing data to a database, you can compare the performance. As for the page size, we all know that viewstate will be quite large when using some components such as the gridview control. There are two key values in Web. config, which can be set to decide whether to store them in the database or to compress them. Sharpziplib is used for compression. bzip is used at the begin
