Computation of Decimal Transcendental Functions Using the CORDIC Algorithm

In this work we propose new decimal floating-point CORDIC algorithms for transcendental function evaluation. We show how these algorithms are mapped to a state of the art Decimal Floating-Point Unit (DFPU), both considering the use of a carry–propagate adder or a carry– save redundant adder. We compared with previous decimal CORDIC proposals and with table-driven algorithms, and we concluded that our approach have significant potential advantages for transcendental function evaluation in state of the art DFPUs with minor modifications of the hardware.
