Abstract: A transaction level (TL) system power estimation method and system are provided. The method includes inserting at least a characteristic extractor into an electronic device of a target system. The characteristic extractor extracts at least a power characteristic of the electronic device when a TL simulation is proceeding. The power characteristic provided from the characteristic extractor is converted to at least a power consumption value by using a power model. The power consumption value is recorded into a power database, for analyzing power consumption of the whole target system. In some embodiments, the TL system power estimation method and system can be applied in the target system with dynamic power management.

Abstract: A full duplex DES cipher processor (DCP) supports to execute sixteen rounds of data encryption standard (DES) operation in four encryption modes and four decryption modes, namely: Electronic Code Book (ECB) mode, Cipher Block Chaining (CBC) mode, Cipher Feedback (CFB) mode, and Output Feedback (OFB) mode for both encryption and decryption. A DCP is composed of an I/O unit, an IV/key storage unit, a control unit, and an algorithm unit. The algorithm unit is used to encrypt/decrypt the incoming text message. The algorithm unit having a crypto engine allows encryption and decryption performed alternately, by sharing the same crypto engine. Since for crypto applications in communication services like T1, E1, V.35, the algorithm unit operation time is much shorter than the data I/O time; in other word, the algorithm unit is in the idle state mostly.
