  • Step 101 Obtain the CPU frequency information, and initially obtain the video level.
  • static detection It is first determined whether static detection can be performed before acquiring the main frequency information. Whether static detection is possible is determined by the operating system of this machine. For example: Windows 98 and previous operating systems do not support static detection, but the operating system after Windows 98 supports static detection. If the operating system supports static detection, the CPU's frequency information is written in the registry. In the embodiment of the present invention, the frequency information of the CPU is read from the registry. The CPU's frequency information usually has a fixed location in the registry. The application interface provided by Windows can directly open the registry and determine whether there is relevant information in this location. If there is information, it supports static detection. If no information exists, static detection is not supported.

  • the CPU's main frequency directly reflects the data processing capability of the CPU. Therefore, after acquiring the main frequency information, the video level of the local machine can be divided according to the main frequency information.
  • the division method is as follows: First, the video level is divided into n levels, respectively, S1 Level, S2 level...Sn level, then divide the range of the main frequency value into n segments in descending order, each segment contains several possible main frequency values. Corresponding to the n-level of the video level and the n-segment of the main frequency division, the highest level of the video level corresponds to the main frequency band with the highest frequency value, and so on, and then the detected main frequency of the CPU is used to match the corresponding main frequency band. According to the main frequency band, the corresponding video level is the video level initially obtained by the local machine.
  • Step 102 Detect the Cache information and adjust the video level.
  • LI Cache size is an important indicator of CPU processing power. For example: Detect LI Cache and L2 Cache separately.
  • LI Cache is a cache that is encapsulated inside the CPU, access speed and CPU
  • the main frequency is the same, and its capacity has a greater impact on the performance of the CPU. The larger the capacity, the higher the performance of the CPU.
  • L2 Cache is a cache integrated outside the CPU.
  • the access speed is the same as the CPU frequency or the motherboard frequency.
  • the main function is to store the backup data and instructions. Its capacity has a great impact on the performance of the CPU, because the video The amount of data that needs to be processed is large. If the L2 Cache has a large capacity, the number of data access exchanges can be reduced, and the video processing speed can be optimized.
  • the capacity of the LI Cache and the L2 Cache is detected by a built-in CPU instruction, and the video level of the local device is adjusted according to their capacity.
  • L2 Cache Take L2 Cache as an example to illustrate the adjustment method as follows:
  • the L2 Cache is divided into n levels according to capacity. Each level corresponds to a video level correction value (this correction range is from -X to +Y, X and Y are positive numbers), and then the detected L2 Cache capacity is used. Match the corresponding level and read the correction value to adjust the video level.
  • the size of the LI Cache is the same as the video level adjustment method and L2 Cache. Therefore, the larger the capacity of LI Cache and L2 Cache, the higher the video level of this unit.
  • Cache is only used as a post-fix. If the Cache failure is detected by the built-in CPU detection command, the level determined by the original frequency is taken as the standard.
  • Step 103 Detect other video level auxiliary information and adjust the video level.
  • Other video level auxiliary information mainly includes:
  • MMX, SSE, SSE2 and 3DNow! are all extended instruction sets of the CPU. Supporting the instruction set is an important basis for reflecting the multimedia processing capability of the terminal.
  • the built-in CPU command detects whether the terminal supports the multimedia instruction set. If it is supported, the video level is higher. This adjustment method is consistent with the above-mentioned dual-core adjustment method.
  • Hyper-Threading Technology can reduce CPU idle time and improve CPU operating efficiency.
  • the built-in CPU command detects whether the terminal supports Hyper-Threading Technology.
  • the video level will be improved. This adjustment method is consistent with the above-mentioned dual-core adjustment method.
  • Step 104 After obtaining the local video level, determine the highest frame rate of the local encoding, and encode the video data of the instant communication by the highest frame rate, as follows:
