WebMake sure to add this file to your project if you are using the sin, cos or sincos macros. 4.5. Linker File The linker file needs to specify the load and run memory locations for the following sections: • CLAProg – this contains the CLA program code. The examples load this code directly into CLA program memory for debug. WebSep 6, 2013 · sin(-A) = -sin(A) This made it so I only needed to calculate sin and cos for one half of the circle. 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)
