Reconfigurable Logic Fabric With Circular Buffers for Runtime Switching

The patent implements dynamic reconfiguration by allowing the logic fabric to change its connectivity and logical functions during runtime without requiring full reprogramming. The configurable logic blocks and routing structures can be dynamically reconfigured through control signals, enabling the system to adapt to changing requirements while maintaining operational continuity and minimizing downtime.

The patent pre-configures multiple logical functions within the same physical hardware structure. By providing a reconfigurable fabric with configurable logic blocks and programmable routing structures that can be programmed once to support multiple future functions, the system prepares for adaptability in advance, eliminating the need for time-consuming reprogramming when functional changes are needed.

The rotating circular buffer structure serves multiple functions: it stores configuration instructions, provides timing control for reconfiguration, and enables sequential loading of different logical functions. This single multi-functional component replaces what would otherwise require separate memory structures, control logic, and timing mechanisms, thereby reducing overall device complexity while maintaining dynamic reconfiguration capability.

The patent merges the configuration storage, instruction execution, and reconfiguration control into a unified rotating circular buffer system. By combining these functions into a single integrated structure that rotates through configuration data, the design eliminates the need for separate configuration memory, control logic, and timing circuits, thereby reducing device complexity while achieving dynamic reconfiguration.
