    Abstract: Implementations include systems, methods and/or devices suitable for use in a memory system that may enhance the performance of error control codes used to improve the reliability with which data can be stored and read. Some implementations include systems, methods and/or devices enabled to generate and utilize soft information for decoding encoded data read from a storage medium. More specifically, some implementations utilize a collection of characterization vectors that include soft information values for bit-tuples that may be read from the storage medium for various combinations of the storage medium characterization parameter values. Some implementations are enabled to determine and utilize read comparison signal values associated with one or more storage medium characterization parameter values. And some implementations are enabled to determine and utilize shifted read comparison signal values associated with one or more storage medium characterization parameter values and an identified error condition.

    Abstract: A high-speed bus interface with an adaptive swing driver. A high speed interface includes a transmitter and a receiver coupled via a bus. The transmitter has an adaptive swing driver and a voltage-regulating-module (VRM). The adaptive swing driver includes a post-driver and a pre-driver. The post-driver provides an adaptive swing output with a dedicated adaptive voltage power supply (VDDQ) and transition emphasis driving capacity with an internal logic voltage supply (VDD). The pre-driver provides the transition emphasis driving capacity with a pull-up and a pull-down signal path to the post-driver. The voltage-regulating-module is configured to supply signal to the adaptive swing driver. The receiver includes a comparator and a bit-error-rate detector. The comparator amplifies the adaptive swing output received from the transmitter via a bus, while the bit-error-rate detector diagnoses the amplified adaptive swing output received from the comparator.

    Abstract: The method for maximizing an unavailability interval includes the steps of initializing the starting frame number of each power saving class fi to 1 and adjusting fi to fi′ when the least common multiple of m1, m2, . . . , mi−1 and mi is not relatively prime. The index i is an integer from 1 to t, mi is the sleep cycle of the ith power saving class, and fi′ is an integer that maximizes common sleep windows of the i power saving classes. The common sleep windows of the t power saving classes are then set as the maximum unavailability interval of the wireless telecommunication device.

    Abstract: A method, computer program product and apparatus for indicating program modifications affecting program performance in an Integrated Development Environment (IDE). The modifications that a developer makes to a program is detected and the code location where these modifications occur is determined. The previous profiling data of the program is acquired. The effect of the modifications on the program performance according to the previous profiling data and the code location where the modifications occur is evaluated. The evaluation results may then be provided to the developer. As a result of the above process, the developer can be aware of the performance problem while he/she is editing the source code so as to make corrections without waiting after the profiling phase, thus greatly shortening the development period.

    Abstract: A method of generating a pumping voltage in an integrated circuit includes receiving an external clock signal from outside of the integrated circuit. The frequency of the received external clock signal is changed according to one or more modulation ratios, resulting in one or more respective modulated external clock signal. The external clock signal or one of the modulated external clock signals is then selected for use as a pump clock signal. The pump clock signal is used for driving the pump capacitance of a pump circuit for generating the pumping voltage.
