Embodiment 1
[0037] See figure 1 , the pseudo-random number seed generation device in this example includes an original pseudo-random number seed generation module, a processor and a storage module connected in sequence, wherein:
[0038] The original pseudo-random number seed generation module is used to generate the original pseudo-random number seed;
[0039] The storage module is used to store the pseudo-random number seed generated last time;
[0040] The processor is used to read a set of original pseudo-random number seeds from the original pseudo-random number seeds currently generated by the original pseudo-random number seed generation module, and read the pseudo-random number seeds generated last time from the storage module, and perform a combination of the two Compare and process to determine whether the two are the same, if they are the same, then re-read a set of original pseudo-random number seeds from the original pseudo-random number seed generation module for comparison...
Embodiment 2
[0058] The original pseudo-random number seed generation module in this example can be a readable and writable temporary memory. This type of memory has an indeterminate state after power-on and before reset, such as instruction registers, program counters, and SRAM memories. The following uses SRAM memories as Example for further detailed description: Due to the RAM structure, the data stored in the SRAM after power-on is related to the power-on speed, temperature and process deviation, and has an indeterminate state. Therefore, the SRAM memory can be used as the original pseudo-random data in this example. The number seed generation module can also use other memories with the same characteristics as the RAM structure as the original pseudo-random number seed generation module in this example. In this example, it is called the original pseudo-random number seed generation module, and the storage module used to store the pseudo-random number seed generated last time in the firs...
