With the development of the field of scientific computing, the rapid generation of high-quality random numbers has become a crucial aspect of research. However, traditional methods are often insufficient in meeting the efficiency and quality requirements of random number generation. In this paper, we propose an improved version of the Mersenne Twister algorithm, implemented on the FPGA platform. By optimizing the characteristic polynomial in the Transform module, the randomness and uniformity of the Mersenne Twister (MT) algorithm are enhanced. The core modules of the algorithm are realized through a parallel structure one the FPGA, with the AXI4-Stream data bus utilized as the protocol for data interaction with peripherals. Finally, the quality of the random numbers by the designed generator is tested, and the results demonstrate that it can efficiently produce high-quality, uniformly distributed random numbers. These numbers are well-suited for applications that require the rapid generation of large quantities and high-quality random numbers, such as Monte Carlo simulations.

In order to meet the needs of the visually impaired to learn Braille and improve the efficiency of teachers teaching Braille, this paper uses Internet of Things technology and embedded technology to design a new type of Braille learning machine to optimize the existing Braille teaching. The Braille teaching system is designed through the MQTT protocol to realize the network control of multiple Braille learning machines. A micro motor is used to control the lifting of a single braille bump, and a dual CPU control architecture is used to control the lifting of the braille bump, which improves its reusability compared with traditional braille boards. We tested the accuracy of Braille conversion, and the experimental results were in line with expectations. This research can better serve the visually impaired and bring convenience to their Braille learning.
