如上图所示，TMU指令集除了sin cos atan等上图所示的指令集外，是否还有asin acos等反三角函数指令集，我想知道手册中哪里能找到这些指令集周期。谢谢各位大佬指示
TMU不支持arcsin或arccos的指令集。您可以做的是利用两个逆向触发函数和TMU对arctan的支持来实现这些函数
// arcsin phi = fabsf(theta); asin_v = phi / sqrtf(1 - (phi*phi)); if (asin_v > 1.0f) { asin_b = 1.5708f - __atan(1.0f / asin_v); } else { asin_b = __atan(asin_v); } if (signbit(theta)) { asin_b = -asin_b; } // arccos acos_v = sqrtf(1 - (phi*phi)) / phi; if (acos_v > 1.0f) { acos_b = 1.5708f - __atan(1.0f / acos_v); } else { acos_b = __atan(acos_v); } if (signbit(theta)) { acos_b = 3.142159f - acos_b; }
