| Abstract: | ARM(Advanced RISC Machines)and DSP have been applied widely in Embedded system design. Based on them, a communication terminal is designed. The hardware and software constitution of this terminal are introduced. The hardware schematic and software realization are presented. This paper emphasises on the hardware interface related with speech processing, data exchange and speech enhancement during speech transmission. |
