The WE DSP32 in AT&T's second-generation programmable digital signal processor with 32-bit floating point arithmetic. This device can be used in a wide varity of complex digital signal processing algorithms such as speech recognition,high speed modems, low-bit rate voice coders, and multichannel signaling system. This paper reviews the LPC analysis and synthesis of speech signal and presents a real time implementation methodology of these algorithms using the WE DSP32. For efficient data handling, circular buffer is proposed. The implementation results show that deep pipelining characteristics of the processor should be fully utilized to satisfy the timing constraints,
