what is xmp

xmp has three meanings: 1. It is an encrypted image format. Its essence is BMP without the file header. The two DWORDs at the beginning of the file store the width and height of the image; XMP files are generally used in games. Only by clearing the game can you see the wonderful ending. 2. It is Intel's Extreme Memory Profile certification. It is an optimization technology used by Intel on memory. It is a memory profile that is used to automatically overclock the memory. 3. It is an open platform for metadata tag files that complies with W3C specifications.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

xmp has three meanings, let’s learn about it below.

XMP (image format)

xmp is an encrypted image format launched by Adobe, which can be opened with PS.

xmp files can be opened with PS, but not all of them can be opened. They can only be opened with photoshop7.0 or above!

XMP does not save any image information similar to jpg. is just the metadata of the file.

The essence is that the BMP in the file header is removed, and the two DWORDs at the beginning of the file store the width and height of the image.

xmp facilitates the exchange of metadata between Adobe applications and various publishing workflows. For example, you can store metadata for a file as a template and then import that metadata into other files.

XMP files are generally used in games. Only by clearing the game can you see the wonderful ending.

XMP (Intel's Extreme Memory Profile certification)

XMP is the abbreviation of Extreme Memory Profile, which was proposed by Intel in September 2007 Memory certification standards for DDR3 and DDR4.

xmp is an optimization technology used by Intel to automatically overclock memory. Intel has launched Extreme Memory technology and formulated Intel Extreme Memory Profiles (Intel XMP Specification). Intel will certify the memory. , the chipset will read the SPD in the memory module, perform targeted optimization and automatic overclocking according to the XMP specifications. That is, xmp is the official overclocked memory configuration file. After it is turned on, the frequency is higher and the memory is read and written faster.

The main function of memory XMP is to overclock the memory frequency. However, XMP is overclocking within the range set by the manufacturer. It is a safe overclocking. XMP is equivalent to writing 2 sets of working configuration files to the memory. Turning on XMP mode in the BIOS allows the motherboard to read the memory configuration file. For example, if the nominal frequency of the memory is 3000MHz, then the XMP mode can allow the memory to run at a frequency of 3000MHz, thereby giving full play to the performance the memory should have.

Similarly, Intel has developed a JEDEC SPD extension for DDR3 SDRAMDIMMs. It uses JEDEC unallocated bytes 176-255 to encode higher performance memory timings. Also called "extended memory configuration" in Chinese, the header contains the following data. The most important of these is the "medium time base" value MTB, which is a reasonable nanosecond (common values ​​are 1/8, 1/12, and 1/16 nanosecond). Many subsequent timing values ​​are expressed in integer MTB units.

The header also includes the number of DIMMs per memory channel that the profile is designed to support; more DIMMs may not work properly.

AMD has also developed an SPD extension set called AMP, which has the same function as XMP.

XMP (Extensible Metadata Platform)

In the entire series of products, as an open source technology, it is provided to developers for free, which means that users can conduct global development on this platform. Additionally, XMP is extensible, meaning it can accommodate existing metadata schemas so the system does not need to be rebuilt from scratch. An increasing number of third-party applications already support XMP.

With XMP-enabled applications, information about projects can be captured during the content creation process and embedded in files and in a content management system. Meaningful descriptions and titles, search keywords, and up-to-date author and copyright information can be captured in a format that is easy to understand, as well as application software, hardware devices, and even file formats.

Most importantly, as other members of the workgroup modify files and assets in their daily work, XMP metadata encoding can be edited and updated in real time.
