    摘要: A system on a chip (SoC) and method of operation are described. A data processor has a processor data word size of p×octets and is configured to handle data items having a data item size which is a non-integer multiple of the processor data word size. A memory controller is configured to write or read data items to a memory as multiples of m×octets. Data can be sent between the data processor and the memory controller on a bus. A data protection code generator is configured to generate a data protection code for a data item generated by the data processor before transmitting the data item and the data protection code over the bus to the memory controller which writes at least one octet including at least a portion of the data item and at least a portion of the data protection code to an address. A data protection code checker is configured to receive a read data protection code and a read data item and to check the read data item for an error using the read data protection code. The memory controller reads at least one octet including at least a portion of the read data item and at least a portion of the read data protection code from a read address.

    摘要: A method and apparatus for handling outstanding interconnect transactions between a master device and an interconnect component. For example, a transaction intervention module coupled to an interconnect component and a master device of the interconnect component. The transaction intervention module is arranged to receive an indication of a functional state of the master device. If the master device is indicated as being in a faulty functional state the transaction intervention module is further arranged to determine whether any interconnect transactions initiated by the master device with the interconnect component are outstanding. If it is determined that at least one interconnect transaction initiated by the master device is outstanding, the transaction intervention module is arranged to finalize the at least one outstanding interconnect transaction with the interconnect component.
