CPLD Implementation of Data Demultiplexing
Yao Zhong, Ming Cui, Wei Pan, Wei Hua Luo · 2024
Modern communication technology focuses on the development of digitalization, and digital multiplexing and demultiplexing technology is an important technology in communication technology. By combining multiple low-speed signals into one high-speed signal, it can improve bandwidth utilization and data transmission efficiency. The paper presents an eight channel tap of a complete 512KHz frame data. By setting up a frame synchronization module, a data counting module, a serial to parallel caching module, a parallel to serial caching module, and an output module, the eight low-speed signals are merged into one high-speed signal. Finally, the code is written using Quartus_II software, and the results are verified through Modelsim simulation and hardware download verification.
