Reconfigurable Circuit Register Matrix Bank Selection

The register structure is segmented into multiple banks (first bank, second bank, third bank, fourth bank) organized in a matrix configuration. This segmentation allows parallel access to different data banks through multiple ports, enabling simultaneous read/write operations that shorten data transfer time while maintaining compact circuit size through efficient spatial organization of register resources.

The patent transitions from a traditional one-dimensional or two-dimensional register array to a three-dimensional matrix structure with rows and columns of registers. This dimensional expansion creates multiple access paths and enables concurrent operations across different rows and columns, significantly reducing data transfer time without proportionally increasing circuit area.

The matrix-organized register banks serve multiple functions: they act as input buffers, output buffers, and intermediate storage simultaneously. The same register structure handles both data input from external circuits and data output to external circuits, as well as temporary storage during reconfiguration operations. This multi-functionality achieves high processing speed without adding dedicated separate memory or processing elements.

The reconfigurable circuit uses its existing register resources in a self-sufficient manner to handle all data input/output operations. The matrix register structure with multiple banks can service itself by performing parallel read/write operations without requiring external memory support or additional processing assistance, thereby maintaining circuit simplicity while achieving high productivity.
