【摘要】 给出了SELP高质量声码器在TMS320VC33DSP上的实现。通过部分定点化、汇编指令优化和数学运算优化等方法,使算法的存储量满足芯片的片上存储能力,运算复杂度仅占用了芯片处理能力的1/4,达到了实时性要求。更多还原

【Abstract】 An implementation of a SELP vocoder with high quality on TMS320VC33DSP is presented in this paper.By turning part of the floating-point instructions into fix-point ones,optimizing assembler instructions and mathmatical operations,the memory cost is reduced to fit the target on-chip memory capacity and the operation complexity takes only1/4of the whole operation ability,meeting the re-quirement of real-time.更多还原
