title = "A RISC-V Processor with Optimized CORDIC-Based Trigonometric Function Accelerator",
abstract = "Trigonometric functions are extensively utilized in engineering applications. Processors typically handle such operations in floating-point format using software-based methods, which exhibit significant latency. By employing an optimized CORDIC algorithm and a hardware architecture that emphasizes resource reuse, this paper presents a RISC-V embedded processor supporting floating-point trigonometric function extension and expands two dedicated trigonometric instructions. Evaluations on the XC7Z020 platform demonstrate that, compared to the processor without extended instructions, the proposed design achieves a speedup of 193× in trigonometric computations with an 18.7\% increase in resource consumption.",
