摘要： A hardware accelerator module is driven by a system processor via a system bus to sequentially process data blocks of a data stream as a function of a parameter set defined by the processor. The module includes a register block adapted to receive parameter sets from the system processor, an accelerator core adapted to receive streaming data, to process data blocks of said streaming data in a manner defined by a parameter set, and to output processed streaming data, and a parameter buffering block adapted to consecutively store a plurality of parameter sets and to sequentially provide the parameter sets to the hardware accelerator core as a function of a busy state of the hardware accelerator core. The parameter buffering block enables to reduce downtimes of hardware accelerators, to increase data throughput, and to reduce the risk of a processor overload in a processor which drives several hardware accelerators.

摘要： In the process for data transmission via data blocks between a transmitting station and receiving station the data blocks each have a synchronization pattern field (SYNC), a header field (HEADER) and an information field (INFORMATION) following the header field. The process includes providing a fixed information field (FIXINFO) in each data block for information to be immediately transmitted without delays for error detection and correction following the synchronization pattern field (SYNC); immediately transmitting each fixed information field (FIXINFO) to the receiving station without information from the header field and independently of any occurring transmission errors after a receiver-side synchronization and testing a remaining portion of each data block for at least one error within a predetermined error detection range in the receiving station and, when the at least one error is detected within the detection range, performing an error correction only for that remaining portion of the data block.

摘要： A communication device and a method for transmitting data in wireless local area networks is provided. The device and method are deployed in networks in which the data information elements include an element identification part, a length statement part and an information part. The device and method enable a broad range of data transmission rates and are full compatible with communicating units operating according to previous modes in which a first data transmission rule defines the acceptable range of values of element identification parts. In the method, a second data transmission rule is implemented in at least one of the communicating units to extend the acceptable range of values of element identifications. The range of values is extended so that a second standard portion of the element identification part marks the information element as a second information element.

摘要： The invention, which relates to a method and an arrangement for interference compensation in a phase-locked loop comprising a voltage-controlled frequency generator, wherein the frequency generator is tuned to a nominal frequency by a tuning voltage Vtune and whose actual frequency is compared with a reference frequency by means of a frequency comparison and is re-adjusted if a deviation is detected via the frequency comparison, in which case, in the event of interference, the tuning voltage Vtune is changed by an interference voltage Vstör that depends on the interference event, and thus a frequency deviating from the nominal frequency is generated, which deviating frequency is corrected again by the phase locked loop, is based on the object to provide a method and an arrangement for interference compensation in a phase-locked loop comprising a voltage-controlled frequency generator, with which a deviation from a predefined nominal frequency is avoided if known interference events occur. The object is achieved in accordance with the invention in a method whereby, if a known interference event occurs, a voltage Vstör which compensates for the interference voltage Vcomp, is generated in synchronism with this with sign inversion and is superimposed on the interference voltage Vstör.
