摘要

本文设计了一种用于语音和音频信号处理的新型应用驱动数字信号处理器LASP24(低成本应用驱动语音处理器，24位数据宽度)。在LASP24上进行了MELP算法和混响算法两种应用。所开发的仿真器可以快速验证这两种算法。该设计采用UMC 0.18mum 1P6M技术，总面积为6.5 mm2。最大时钟频率约为100 MHz，单1.8V电源

A low-cost and application-driven digital signal processor for speech/audio processing

In this paper, a new application-driven digital signal processor, called LASP24 (low-cost application-driven speech processor, 24-bit data width), for speech and audio signal processing is designed. Two applications, MELP and reverberation algorithms, are performed on LASP24. The developed emulator can quickly verify these two algorithms. The design has been integrated in the total area of 6.5 mm2 by using UMC 0.18mum 1P6M technology and fabricated. The maximum clock frequency is about 100 MHz with a single 1.8V supply
