This is an MCU and Host CPU Communication Block Diagram Template. It details the modular architecture of how a Host CPU (running Linux applications and drivers) interacts with an MCU (featuring user applications, various drivers like GPIO, I2C, UART, and APIs), leveraging shared memory and IPC channels for communication. Ideal for embedded engineers, hardware developers, or system architects, this template visualizes the block-level interaction to aid in embedded system design and inter-processor communication optimization.
