Data processing apparatus for executing an access instruction for N threads

A data processing apparatus 10 for executing an access instruction for n threads in order to access data values for the n threads includes storage circuitry 100 that stores data values associated with the n threads in groups defined by storage boundaries (e.g. cache lines). The data processing apparatus also includes processing circuitry 80 that processes the access instruction for a set of threads at a time (where each set of threads comprises fewer than n threads) and splitting circuitry 110, responsive to the access instruction, to divide the n threads into multiple sets of threads, and to generate at least one control signal identifying the multiple sets. For each of the sets, the processing circuitry responds to the at least one control signal by issuing at least one access request to the storage circuitry in order to access the data values for that set. The splitting circuitry determines into which set each of the n threads is allocated having regards to the storage boundaries. Splitting ...

A data processing apparatus and method for performing lock-protected processing operations for multiple threads

Номер: GB0002528056A

Processing circuitry 10 performs processing operations required by a plurality of threads 17, 18, 19, the processing operations including a lock-protected processing operation with which a lock 55 is associated, where the lock needs to be acquired before the processing circuitry performs the lock-protected processing operation. Baton maintenance circuitry 35 is used to maintain a baton in association with the plurality of threads, the baton forming a proxy for the lock, and the baton maintenance circuitry being configured to allocate the baton between the threads. Via communication between the processing circuitry and the baton maintenance circuitry, once the lock has been acquired for one of the threads, the processing circuitry performs the lock protected processing operation for multiple threads before the lock is released, with the baton maintenance circuitry identifying a current thread amongst the multiple threads for which the lock-protected processing operation is to be performed ...
