//SACM_Decode.asm: This file includes Kernel .
// It is to be prepared by design deptartment.
// name of Algorism
// Author: Arthur, SamSung,
// Date: 2003/01/28 V1.0 : Template release
//
// Note:C_DECODE_OUT_LENGTH
// 1. This template is made to facilitate the collaboration between RD5 and SA.
// 2. Consistency in programming style can benefit both parties and shorten
// the developement lead time.
// 3. Modulization can bring better integration and promote better collaboration.
// 4. Robustness design is convenient for users to adopt this algorithm.
// 5. Efficiency and Performance in coding style will enhance the core competence
// of this algorithm.
