In this paper,we designed a time-division multiplexing SHA-224/256 IP core based on the algorithm's similarity.The IP core used parallel structure and pipeline technology to simplify the hardware designing and improved the speed of the IP core.Finally we implemented the IP core in Altera's EP2C20F484C6 FPGA.We also gave the result of timing simulation which demonstrates the IP core can run under the 100MHz frequency.This IP core could be widely used for digital signature system and double-key system of 3DES.
