摘要： A data processing apparatus and method of data processing are provided. The data processing apparatus comprises execution circuitry configured to execute a sequence of program instructions. Checkpoint circuitry is configured to identify an instance of a predetermined type of instruction in the sequence of program instructions and to store checkpoint information associated with that instance. The checkpoint information identifies a state of the data processing apparatus prior to execution of that instance of the predetermined type of instruction, wherein the predetermined type of instruction has an expected long completion latency. If the execution circuitry does not complete execution of that instance of the predetermined type of instruction due to occurrence of a predetermined event, the data processing apparatus is arranged to reinstate the state of the data processing apparatus with reference to the checkpoint information, such that the execution circuitry is then configured to recommence execution of the sequence of program instructions at that instance of the predetermined type of instruction.

摘要： A data processing apparatus and method are provided. The data processing apparatus is configured to perform data processing operations in response to data processing instructions including a multiple operation instruction, in response to which multiple data processing operations are performed. The data processing apparatus comprises two or more data processing units configured to perform the data processing operations and an instruction arbitration unit configured to perform sub-division of a multiple operation instruction into a plurality of sub-instructions and to perform allocation of the plurality of sub-instructions amongst the two or more data processing units, wherein each sub-instruction is arranged to cause one of the two or more data processing units to perform at least one data processing operation of the multiple data processing operations. The instruction arbitration unit is configured to perform the sub-division and the allocation dynamically in dependence on a current availability of a resource for each of the two or more data processing units, enabling more efficient usage of the resources of each of the data processing units to be made.
