摘要：
In this paper a DCT algorithm is implemented which requires only 2N DCT coefficients in the look-up table. Fixed-point methods are used, inputs are represented as 14-bit fixed-point numbers, and computation is done in double precision to increase accuracy. Results are presented as 16-bit values.
