    摘要: A clock control circuit for a Rambus DRAM is provided which reduces power consumption by determining in advance whether an applied command is a read or current control command, and enabling a clock signal for externally outputting an internal data only during the read or current control command. Our circuit includes: an input signal detecting unit for generating an enable signal when one of a first comparing signal comparing an address value of the selected Rambus DRAM with a device address value of a COLC packet, and a second comparing signal comparing the address value of the selected Rambus DRAM with a device address value of a COLX packet is enabled, and when the command is a read or current control command; a signal generating unit for generating a clock enable signal for externally outputting an internal data when one of the first and second comparing signals is enabled; an output signal maintaining unit for outputting a control signal for maintaining the clock enable signal to the signal generating unit in the read or current control command; and an output signal control unit for outputting a control signal for controlling generation of the clock enable signal to the signal generating unit, when the command is not the read or current control command.

    摘要: A spectrum analysis engine (SAGE) that comprises a spectrum analyzer component, a signal detector component, a universal signal synchronizer component and a snapshot buffer component. The spectrum analyzer component generates data representing a real-time spectrogram of a bandwidth of radio frequency (RF) spectrum. The signal detector detects signal pulses in the frequency band and outputs pulse event information entries output, which include the start time, duration, power, center frequency and bandwidth of each detected pulse. The signal detector also provides pulse trigger outputs which may be used to enable/disable the collection of information by the spectrum analyzer and the snapshot buffer components. The snapshot buffer collects a set of raw digital signal samples useful for signal classification and other purposes. The universal signal synchronizer synchronizes to periodic signal sources, useful for instituting schemes to avoid interference with those signals.
