Some applications such as RSA encryption/decryption need integer arithmetic operations with many bits. However, such operations cannot be performed directly by conventional CPUs, because their instruction supports integers with fixed bits, say, 64 bits. Since the CPUs need to repeat arithmetic operations to numbers with fixed bits, they have considerably overhead to execute applications involving integer arithmetic with many bits. On the other hand, this paper implements hardware algorithm for such applications in the FPGAs for further acceleration. However, the implementation of hardware algorithm is usually very complicated and debugging of hardware is too hard.
