riscv-mathlib

High performance mathematics library for RISC-V platforms

Current Progress

• some typical functions are done for double precision floating point number
• other functions will be updated soon

How To Use

call.c:

#include <stdio.h>

double _rv_sin(double x);
int main(void)
{
        double x=0.5;
        double y;
        y=_rv_sin(x);
        printf("HEX:%llx\n", y);
        printf("DEC:%lf\n",y);
        return 0;
}

command:

 $ riscv64-unknown-elf-gcc call.c sin.S -o a.out
 $ spike pk a.out
