| Abstract: | In order to improve generic performance for(code excitation linear prediction) CELP speech system designed by DSP processor,and overcome some shortcomings,which are high cost and complexity of design and stability from CELP speech system constructed by ARM and DSP processors,a single S3c2410 processor is employed to implement the CELP codec speech system,including speech algorithm analysis,hardware design and software design.The results of experiment show that the CELP speech system implemented by the single S3C2410 microprocessor,has better generic performance and stability with decreasing the complexity and cost of design |
