Abstract: |
GIDC-C was designed for computer network. Fabricated with very large scale integration technology, the chip is a soc which include CPU,RSA,DES module. The top-down design methodology was adopted. The ASIC scheme and detailed structure of CPU,RSA,DES were presented. Power consumption, reliability and simulation is analyzed. The result of simulation and verification validates that the circuit works stably and reliably. The Encryption rate was reached to 5 times per second for RSA and 2?Mbit per second for DES. |
