I also setup pointers to my output arrays and this also sped up my calculations. I'm not sure of this, but I believe that my compiler vectorized my calculations. A third was to use: sin(A+dA) = sin(a)*cos(dA) + cos(a)*sin(dA) WebApr 6, 2024 · 5th Order Polynomial Fixed-Point Sine Approximation. Here is a simple fixed-point approximation to sin (and cos) appropriate for embedded systems without dedicated floating-point hardware. It is accurate to within ±1/4096 (0.01% Full-Scale). No lookup-table is required, and portable C code is available. dhl growth
