| Abstract [eng] |
In this paper, we report a hardware implementation scheme and results of a Loeffler algorithm based 2-D discrete cosine transform codec. This codec performs a full 2-D DCT encoding and 2-D IDCT decoding. It is fully functional, capable of being used in any hardware coding algorithm. The Loeffler algorithm is one of the newest and most effective fast DCT algorithms for hardware implementation. 2-D DCT/IDCT was computed by applying 1-D operations on matrix using a row/column approach. For a hardware implementation, additional data buffers and control logic is used to perform 2-D transforms. Since hardware implementation is less accurate than mathematical modelling, more errors occur in the computational results. However, differences are small and cannot be directly observed. |
