Transfer (data) from main memory to temporary storage in readiness for later use.
- ‘It's primarily designed to prefetch large quantities of data to help prevent processor stalls.’
- ‘The accelerator scours a page and prefetches the content behind each link.’
- ‘The target can thus be prefetched before the actual address has been calculated and placed in a register.’
A process or instance of prefetching data.
- ‘Some changes were made to the hardware prefetch mechanism to increase its efficiency, in addition to software prefetches now being stored in the trace cache.’
- ‘This process is called prefetching, and it generally works well.’
- ‘A mechanism is also described to improve the timeliness of a prefetch by suitably adjusting the value of N after observing the usefulness of the prefetched instructions or data.’
- ‘In fact, all contemporary CPUs have their own data prefetch mechanisms, which allow them to move data into the cache memory.’
