decryption.
5 CONCLUSION
Based on the characteristics of digital signal process-
ing chip TMS320VC5416 of TI company and the
audio codec chip TLV320AIC23, by writing appli-
cations and debugging software and hardware in the
CCS integrated development environment, this thesis
designs and implements a speech secure communica-
tion system which can encrypt or decrypt audio signal
through cyclic xor algorithm. The system test results
show that it can meet the requirements of real-time
signal processing and can be used as a universal plat-
form for voice signal processing algorithms research
and real-time implementation ...
