摘要： Apparatus suitable for detecting a fault in a processor comprises a monitor which receives input and output signals from the processor and generates a hash index key which is used to access entries in a hash table. The entries may include actions such as setting a timer so that the response of an output to a change of state of an input may be confirmed as valid within a specified time interval.

摘要： The disclosure relates to cut-through forwarding module, an integrated circuit, a semiconductor device and a method of receiving and transmitting data frames in a cut-through forwarding mode. The cut-through forwarding module processes received data frames in data blocks. The module comprises a pre-loading unit for storing a first data block of a received data frame. The stored first data block may be pre-loaded by the pre-loading unit in a transmitter unit before a receiver unit receives a subsequent data frame. The processing unit controls the transfer of a first data block to the pre-loading unit and controls the use of a pre-loaded data block as a first data block of a data frame to be transmitted.

摘要： A multi-port transmitter device for transmitting at least partly redundant data is described. The multi-port transmitter device comprises at least two transmitters comprising respective transmitter buffers. One transmitter is a master transmitter that issues a request to the processor to provide a data block when the transmitter buffer of the master transmitter has free space to store a data block. The processor is arranged to copy at least one data block of data stored in an external memory from the external memory to respective positions in a local buffer. The processor is arranged to, in accordance with a predefined sequence, sequentially initiate transfer of the data block from the respective position of the data block in the local buffer to the transmitter buffers of the at least two transmitters in response to a request from the master transmitter to provide a data block.

摘要： Apparatuses, methods, and systems are configured to perform unambiguous parameter sampling in a heterogeneous multi-core or multi-threaded environment by masking one or more thread requests; and, in response to bus activity ceasing for the one or more masked thread requests and completing any routine being processed for the one or more masked threads, processing a command by executing at least one of a command routine or a command thread, wherein the command routine or the command thread reads the parameter using thread atomicity with deterministic synchronization. One or more thread requests may be selected for masking by monitoring thread activity for each of a plurality of threads.

摘要： An error correction apparatus comprises an input for receiving data. The received data includes error-check data. The apparatus also includes a processing resource arranged to calculate parity check data. A data store is coupled to the processing resource for storing look-up data for identifying, when in use, a location of an error in the received data. The look-up data is a compressed form of indexed error location data.

摘要： There is provided a network interface module, and a method of implementing deterministic response frame transmission therein. The network interface module comprises a processor core arranged to execute a set of threads, the set of threads comprising at least one transmit thread arranged to cause a response frame to be transmitted upon expiry of a minimum response period from a response triggering event occurring. The network interface module further comprises a timing component arranged to output a masking timeout signal indicating expiration of successive masking timeout intervals, and a masking component arranged to mask the transmit thread from being scheduled for execution by the processing core. The masking component being further arranged to receive the masking timeout signal output by the timing component and to unmask the transmit thread upon expiry of a masking timeout interval.
