An Adaptive Precision CORDIC Processor with UART Interface for FPGA-Based Edge Computing

This paper presents a novel configurable CORDIC (Coordinate Rotation Digital Computer) architecture optimized for implementing an FPGA (Field Programmable Gate Array). The proposed design features two key innovations: (1) an adaptive iteration control scheme that automatically adjusts computational precision based on input characteristics, and (2) an integrated UART interface for convenience in data transport between ICs. The integrated UART interface enables applications that require multiple processors.
