Design and implementation of heterogeneous dual core data transmission system based on FSMC bus

FSMC is an interface technology used when STM32 processor needs to expand its functions in some applications. This paper takes the FSMC bus of stm32f767 as an example, introduces the method that STM32 series chips connect FPGA through FSMC bus, opens a section of FIFO space in FPGA, and connects the FIFO memory to the FSMC bus of STM32. FIFO is used as a memory of STM32. The hardware circuit design and software interface design are given. And the data transmission of heterogeneous dual core is simulated and verified in the experiment, which has certain reference significance to realize the data transmission of heterogeneous dual core processor through FSMC bus.
