Abstract

High-speed and dependable data transfer systems are required by the increasing need for effective embedded system communication. A commonly used synchronous protocol enabling smooth communication among microcontrollers, memory devices, and peripheral components, the Serial Peripheral Interface (SPI) allows for great interaction. The design and execution of an SPI-based embedded system using the MicroBlaze soft processor on a ZedBoard 7000 FPGA platform are given here. Custom Verilog-designed SPI Master and Slave modules combined with an AXI interface for effective FPGA-based design produce the system. First building a Vivado block design including the MicroBlaze processor, AXI interconnect, and SPI module, followed by HDL wrapper creation, simulation, and bitstream deployment on hardware is part of the implementation. S25FL256SAGMFB003 SPI Flash Memory confirms the functionality of the system, with UART communication used for verification. The experimental results validate effective FPGA-based SPI read/write operations, therefore showing the dependability and effectiveness of such implementation with MicroBlaze. Real-time hardware testing and Vivado simulations offer performance validation. The study emphasizes the benefits of FPGA-based SPI controllers over conventional microcontroller-based solutions in terms of speed, adaptability, and reliability. Future research might concentrate on maximizing SPI communication speed, adding more peripherals, and enlarging the system for real-time industrial uses.
