Implementation of SPI Protocol with Adaptive Baud Rate and Configurable NBit Transmission

The Serial Peripheral Interface (SPI) protocol is a widely used synchronous communication protocol that enables high-speed data exchange between microcontrollers and peripheral devices. This project focuses on the implementation of the SPI protocol with an adaptive baud rate using Verilog Hardware Description Language (HDL). The adaptive baud rate functionality ensures flexibility by dynamically adjusting the communication speed based on the requirements of the connected devices, enhancing performance and compatibility.

The Verilog-based SPI implementation includes modules for Master-Slave configuration, clock generation, data transmission, and reception, as well as an adaptive baud rate controller. The adaptive baud rate module dynamically adjusts the SPI clock frequency using programmable settings, ensuring seamless communication across devices with different speed requirements.
