| Abstract: | This paper presents an encryption engine composed of a single chip processor and a dual port RAM. The fundamental principle and the work flow of the encrypfion engine are also discussed. Dual port RAM supports intermitting system and makes controlling single chip processor and calculation single chip processor parallel-work synchronizingly and harmoniously. Dual port RAM connects controlling single chip processor and calculation single chip processor flexibly and matches their transmitting rate and processing ability, and improves the effeciency of encryption and decryption, controlling single chip processor and the host computer can have a full double communication.This transmission can save the time of controlling single chip processor and improve the efficiency. |
