Abstract: According to the chaotic communication method and system based on complex modified projective difference function synchronization provided in the present invention, when a chaotic signal has a relatively small amplitude, the amplitude of the chaotic signal can be adjusted by adjusting a proportional matrix, so as to mask plaintext better. Moreover, a robust controller is designed according to a filtered signal and a second coupling function, to ensure complex modified projective difference function synchronization, and such synchronization allows the bit error rate to be zero theoretically.

Abstract: A semiconductor package comprises a controlled voltage domain (CVD) and a master voltage domain (MVD). The MVD comprises an error-tolerance control (ETC) circuit. A basic execution block in the CVD generates a basic output value, based on at least two input values. A test execution block in the CVD generates a test digital root, based on digital roots of the input values. A digital root comparator in the CVD determines whether a digital root of the basic output value matches the test digital root. An error reporter in the CVD sends an error report to the ETC circuit in response to a determination that the digital roots do not match. The ETC may automatically adjust at least one power characteristic of the CVD, based on the error report. Other embodiments are described and claimed.
