文章介绍了TMS320VC5409 的在语音处理方面的一个应用电路，阐述了系统的硬件和软件设 计。系统以TMS320VC5409 的外围扩展芯片TLC320AD50 为语音采样电路，利用McBSP 接口、DMA、 LPC 线性预测编码算法实现了语音的压缩、存储、变速、播放功能

Wishbone to LPC (Low-Pin Count) Bridge, includes master and slave modules. Supports 8-bit I/O Read and Write cycles, 8-bit Memory Read/Write cycles, DMA cycles, and up to 32-bit Firmware memory read/write cycles. Serial IRQ support is also provided.
