Abstract

In order to solve the problem of low speed of the equal precision digital frequency meter based on MCU and FGPA, this paper proposed a new communication protocol between MCU and FPGA, in which a 16-bit data bus was applied for data parallel transmission and the FSM was used to realize 32-bit data transmission within the FPGA; and meanwhile, in order to ensure the stability of the system and prevent the frequency measuring error arising from the protocol problems, the program used asynchronous FIFO as an alternate communication channel and defined the FIFO data transmission cycle, which ensured no data loss caused by FIFO overflow during the data transmission. The results show that all the functions can meet the requirement, which proves the effectiveness of the proposed program.
