An apparatus for reducing instruction re-fetching in a multithreading processor configured to concurrently execute a plurality of threads is disclosed. The apparatus includes a buffer for each thread that stores fetched instructions of the thread, having an indicator for indicating which of the fetched instructions in the buffer have already been dispatched for execution. An input for each thread indicates that one or more of the already-dispatched instructions in the buffer has been flushed from execution. Control logic for each thread updates the indicator to indicate the flushed instructions are no longer already-dispatched, in response to the input. This enables the processor to re-dispatch the flushed instructions from the buffer to avoid re-fetching the flushed instructions. In one embodiment, there are fewer buffers than threads, and they are dynamically allocatable by the threads. In one embodiment, a single integrated buffer is shared by all the threads.

A data processing apparatus has address translation circuitry which is responsive to an access request specifying a virtual address, to perform a multi-stage address translation process to produce, via at least one intermediate address, a physical address in memory corresponding to the virtual address. The address translation circuitry references a storage unit, with each entry of the storage unit storing address translation information for one or more virtual addresses. Each entry has a field indicating whether the address translation information is consolidated address translation information or partial address translation information. If when processing an access request, it is determined that the relevant entry in the storage unit provides consolidated address translation information, the address translation circuitry produces a physical address directly from the consolidated address translation information. If on the other hand the relevant entry stores partial address translation information, the address translation circuitry produces an intermediate address from the partial address translation information and then performs the remainder of the multi-stage address translation process. Such an approach provides the performance benefits associated with a consolidated entry mechanism within the storage unit, whilst also allowing certain problem cases to be handled correctly and in an efficient manner.
