基于altera ep2c8双口RAM

基于cordic算法的DDS的Verilog代码。经过仿真验证，绝对可靠。(Based on cordic algorithm DDS Verilog code. Through the simulation, is absolutely reliable.)

说明：  This paper analyzes the cryptography scheme of the Trust Platform Model(TPM). The focus of the discussion would be the comparison of elliptic curve cryptography and the nowadays widely used 2048-bit RSA in evaluating which would be better suited to be used on TPM. A TPM implementation scheme based on ECC is proposed, which includes encryption and decryption schemes, signature and verification scheme, key agreement scheme. Corresponding examples of TPM commands would also be given.
