Provides a hardware-efficient approach to arctangent calculation that reduces circuit complexity while maintaining approximation accuracy, making it suitable for applications requiring fast mathematical processing.

Conventional arctangent computation can require complex or resource-intensive circuitry, creating challenges in implementing efficient mathematical operations for digital signal-processing and embedded applications.

Provides a hardware-based arctangent approximation circuit that generates approximation outputs and uses comparator results, a selected K value and multiplexer-based selection to minimise computational error while reducing the complexity of arctangent calculations.

Implements arctangent approximation through hardware-based mathematical operations and comparator-driven K-value selection, providing a lower-complexity approach to achieving an accurate approximation suitable for digital signal-processing applications.
