| Title: | A MEMORY AND COMPUTATION EFFICIENT STRUCTURE FOR MPEG POLYPHASE SYNTHESIS | ||
| Authors: | Mohamed Mansour; Texas Instruments, Inc. | ||
| Abstract: | We propose a new structure for polyphase synthesis in MPEG-1 audio standard. The algorithm is based on factorizing the DCT matrix in a way similar to FFT factorization. The proposed algorithm reduces the memory requirements significantly even with direct implementation. With optimized implementation, the computational requirement can be reduced considerably as well. | ||
