I have a idct C code for mpeg-4 decoder,the algorithm which used is AAN's alg
now I'm confused because this alg need only 5 multipliers when 1D process,and move the other 8 multipliers to inverse quant, the problem is, if I want to reduce the mult operation, is the other 8 mult implement with LUT when dequant?otherwise this AAN alg does not reduce the mult operation(5+8>11 when use LLM algorithm)
