A system, having a stream cache and a storage. The stream cache includes a stream cache controller adapted to control or mediate input data transmitted through the stream cache; and a stream cache memory. The stream cache memory is adapted to both store at least first portions of the input data, as determined by the stream cache controller, and to further output the stored first portions of the input data to a processor. The storage is adapted to receive and store second portions of the input data, as determined by the stream cache controller, and to further transmit the stored second portions of the input data for output to the processor.

Methods and apparatuses for processing data are provided. In one embodiment, a data processing operation which is assigned a predefined maximum duration is started. The progress of the data processing operation is checked at a predefined point in time and a priority of the data processing operation is changed on the basis of the progress of the data processing operation.

In the case of devices with a program-controlled circuit arrangement operating program instructions are necessary for their operation. In order to reduce the storage space necessary for this, in the case of devices which have a connection (6) to a data transmission network (7) in any case, the operating program instructions are not held in the device, but loaded via the data transmission network (7). For this purpose the circuit arrangement (1) has a start procedure memory (3), in which is stored a start procedure set up in such a way that for its execution a processor unit (2) connects up via the data transmission network (7) by means of the interface (6) to an operating program server and from this loads operating program instructions into a main memory (5) connected to the processor unit (2). The storage space required for the start procedure memory (3) can be further reduced, if the start procedure embedded in it is set up so that the processor unit (2) loads the instructions, which are necessary for connecting to the operating program server and for loading from this the operating program instructions, from a download procedure memory (4).

An A/D converter arrangement comprises an A/D converter (6) to which analog signals from a plurality of signal channels (2) can be fed for A/D conversion. With the help of an appropriate control means (8), converter parameters of the A/D converter (6) or even other operating parameters of the A/D converter arrangement, such as certain functions performed in response to an A/D conversion which has been carried out for example, are set in a channel-specific way as a function of the signal channel (2) which is to be converted at the time.

A data processing device includes at least one first and one second component which are coupled to one another. The first component is operable in a first endian mode, while the second component is operable in a second endian mode, which is different from the first endian mode.
摘要:
A method and device for the uniform output of asynchronously transmitted digital values is provided, including: receiving the digital values in a receiver from a transmission path; outputting the digital values from the receiver on the basis of an output clock for further processing; transmitting the digital values to the transmission path by a transmission device of the receiver, determining the amount of the digital values received by the receiver in relation to the time; adjusting the output clock on the basis of the determined amount in such a way that the digital values are outputted at the frequency with which on time average the receiver receives the digital values; and adjusting a transmission clock of the transmission device to correspond to the output clock of the receiver.
摘要:
A method for transferring data between a first device and a second device is provided. In the method an address identifying the second device is output by the first device or an address generating device connected downstream thereof. An association between the address and the device addressed as a result, and/or the data that are to be transferred are manipulated, during the transfer, in dependence on the outputted address.
摘要:
A DSL communication apparatus with lifeline functionality is provided, the DSL communication apparatus (3) in particular being suitable for CVoDSL (“Channelized Voice over Digital Subscriber Line”) transmission. The DSL communication apparatus (3) comprises a central processing unit (11) which detects a local power failure state of a local power supply unit (23) being associated with the DSL communication apparatus (3). In this case, the central processing unit (11) changes the operation of the DSL communication apparatus (3) from a normal operation mode to an intermediate operation mode, generates an interrupt for stopping a voice coprocessor unit (8), initializes a download of a lifeline operation firmware from a FLASH memory (12) to the voice coprocessor unit (8), and then starts a new initialization of the voice coprocessor unit (8). Thereafter, the central processing unit (11) changes the operation of the DSL communication apparatus (3) from the intermediate operation mode to the lifeline operation mode by switching the power supply of the DSL communication apparatus (3) from the local power supply unit (23) to an auxiliary power supply unit (20) being coupled to the transmission line (1).
摘要:
A data transmission device forwards data that have been received from a first device, intended for a second device, to the second device. The data transmission device is distinguished in that it has connections for connecting at least two data buses and can output data received by a first data bus either onto the same data bus or onto another data bus immediately or later. Therefore, the data transmission device can be used selectively, alternately or simultaneously as a DMA controller and a bus bridge. It also has additional functions unrelated to DMA controllers and bus bridges.
