Hybrid SPI Circuit Timing Control for Wireless LAN

The patent divides the control system into two segments: software for high-level configuration and hardware (finite state machine) for precise timing control. This segmentation allows software to handle adaptability while hardware ensures precision, resolving the contradiction between ease of manufacture and manufacturing precision.

The finite state machine acts as an intermediary between software control and the SPI interface hardware. It translates software commands into precisely timed hardware signals, enabling both ease of software programming and accurate critical timing adjustment.

The control functionality is segmented into software (providing adaptability) and hardware finite state machine (providing reliable timing). This division allows the system to maintain adaptability while achieving the reliability needed for high-performance wireless LAN communication.

The patent replaces software-based timing control (prone to errors) with hardware-based finite state machine control for critical timing functions. This substitution maintains adaptability through software while achieving reliable, error-free timing control through hardware.

The system is segmented so that the complex timing control logic resides in a dedicated finite state machine hardware module, while the main software remains simple and high-level. This segmentation concentrates complexity in a specialized component rather than distributing it throughout the entire system.

The finite state machine serves as an intermediary that handles complex timing logic, shielding the main software from complexity. The software interacts with the FSM through simple commands, while the FSM manages the complex state transitions and timing sequences internally.
