Description: When implemented in the sinx function, please note the following: Suppose the input data x = tπ Time 2. T the range of (-1 ,..., 1), which enter the angle (-π, ..., π), corresponds to the dsp using (8000h ,..., 7FFFh) said. According to the monotonicity of sin function will be (0- π/2) and so is divided into 128 intervals, calculated the value of each discrete point of sin exist in the table _SinTab, the final value of the input of t is worth look-up table to find the closest to the output. 3. Determine the output value of the positive and negative situations sinx. t in the range (-1 ,..., 1), corresponding to the dsp using (8000h ,..., 7FFFh) that can be seen that the maximum bit size of angle x (-π, ..., 0) or (0 , ..., π), so the maximum value can be entered on Step 2 bits of data for processing: When the highest bit is 1, sinx =- sin (x), or sinx = sin (x).
