【摘要】 目前,较低价位的DSP芯片通常只有32k以下的片内存储量,但其速度指标往往有富裕.文章在分析研究了传统重迭保留法的基础上,提出了将序列进行不同于传统分段法的分段思路,以降低对DSP芯片存储容量的要求.充分发挥了低价位DSP芯片的容量和速度的综合性能,能满足实时处理的要求.更多还原

【Abstract】 The current cheap DSP chips only have storage space below 32k,but often have faster speed than needed.Based on the analysis of traditional overlap-save method,this paper propose a new application--letting the segmental output length be much less than that of the impulse response,in order to reduce the demand for DSP space,and to make full use of the comprehensive feature of DSP speed and space.更多还原
