Abstract: An integrated circuit (IC) for optimizing data presentation to an external memory interface bus is provided. The IC is in communication with the external memory via the external memory interface bus. The IC includes an encoder that may encode the data that are being sent to an external memory. The encoder encodes the data based on the logic value of the majority of bits in the data. The encoder is capable of setting a status bit to indicate that the data are encoded. Further connected in series with the encoder is a parity generator that sets the parity bit logic value based on whether the number of logic 1s in the data, along with the status bit, is even or odd. The IC also includes a parity checker to detect whether any error occurred in the data during transmission. The decoder within the IC decodes the data to the original data.

Abstract: Methods for synthesizing Salacinol, its stereoisomers, and analogues, homologues and other derivatives thereof potentially useful as glycosidase inhibitors are described. In some embodiments the compounds of the invention may have the general formula (I) or (II): The synthetic schemes may comprise reacting a cyclic sulfate with a 5-membered ring sugar containing a heteroatom (X). The heteroatom preferably comprises sulfur, selenium, or nitrogen. The cyclic sulfate and ring sugar reagents may be readily prepared from carbohydrate precursors, such as D-glucose, L-glucose, D-xylose and L-xylose. The target compounds are prepared by opening of the cyclic sulfates by nucleophilic attack of the heteroatoms on the 5-membered ring sugars. The resulting heterocyclic compounds have a stable, inner salt structure comprising a heteroatom cation and a sulfate anion. The synthetic schemes yield various stereoisomers of the target compounds in moderate to good yields with limited side-reactions. Chain-extended analogues of Salacinol are also described.

Abstract: A TDD antenna array S-CDMA system for increasing the capacity and quality of a wireless communications is disclosed. By simultaneous exploiting the spatial and code diversities, high performance communications between a plurality of remote terminals and a base station is achieved without sacrificing system flexibility and robustness. The time-division-duplex mode together with the inherent interference immunity of S-CDMA signals allow the spatial diversity to be exploited using simple and robust beamforming rather than demanding nulling. Measurements from an array of receiving antennas at the base station are utilized to estimate spatial signatures, timing offsets, transmission powers and other propagation parameters associated with a plurality of S-CDMA terminals. Such information is then used for system synchronization, downlink beamforming, as well as handoff management. In an examplary embodiment, the aforementioned processing is accomplished with minimum computations, thereby allowing the disclosed system to be applicable to a rapidly varying environment. Among many other inherent benefits of the present invention are large capacity and power efficiency, strong interference/fading resistance, robustness power control, and easy hand-off.
