specific Embodiment approach
[0058] In the embodiment of the present invention, the gradient DCT transformation and quantization transmission methods are as Figure 7 , its specific implementation is as follows:
[0059] S2.1: The number of floating-point numbers contained in the known Gradient is Num, which is stored on the GPU when it is calculated. According to the number of floating-point numbers contained in the Gradient is Num, record the square matrix G 1 ={Gradient i , 0i Represents the i-th floating-point number in the Gradient. Remember the square matrix G 2 ={Gradient i , n*nk (0≤k<Num / (n*n)), wherein, " / " means division and rounding, and the G subscript k means the index of the divided square matrix. The remaining Num% (n*n) floating-point numbers, wherein "%" means division and taking the remainder, the number of floating-point numbers is less than n*n, and the number that cannot form a square matrix is recorded as G';
[0060] S2.2: according to the number of square matrices Num / (n*n...
