Summary: 
In this paper, the hardware architecture of a CORDIC-based Arithmetic Processor utilizing both angle recoding (ARD) CORDIC algorithm and scaling-free (SCFE) CORDIC algorithm is proposed and implemented in 180 nm CMOS technology. The arithmetic processor is capable of calculating the sine, cosine, sine hyperbolic, cosine hyperbolic, and multiplication function. The experimental results prove that the design is able to work at 100 MHz frequency and requires 12.96 mW power consumption. In comparison with some previous work, the design can be seen as a good choice for high-throughput low-energy applications.
