Abstract: A real-time 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.

Abstract: 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.

Abstract: The present invention relates to a small size decoder reducing power consumption and more particularly to a series reed-Solomon decoder synchronized with a bit clock signal. In a Reed-Solomon decoder according to the present invention, the syndrome calculation part comprises a classification element for classifying the input coding data into an even data and an odd data and for calculating, in series, coefficient of the syndrome polynomial on bit-by-bit basis, being synchronized with a bit clock signal. The error position and estimation polynomial calculation part comprises a classification element for classifying an initial syndrome polynomial, a correction syndrome polynomial, an initial deletion pointer polynomial and an initial deletion pointer polynomial into an even data and an odd data and for an error value polynomial and an error position value polynomial on bit-by-bit basis, being synchronized with a bit clock signal.
