A method and a processor may include storing a first set of data in a data array in a cache unit substantially concurrently to reading a second set of data from the data array, and using the second set of data to generate error correction data corresponding to the first set of data. A method or processor may include reading an entry from a cache in a processor and executing two or more error detection mechanisms on the entry substantially concurrently.

System and method for error correction in cache units

Apparatus and computing systems associated with data pre-fetching are described. One embodiment includes a processor that includes a first unit to store data corresponding to a load instruction and an instruction pointer (IP) value associated with the load instruction. The processor also includes a second unit to produce a predicted demand address for a next load instruction, the predicted demand address being based on a constant stride value. The processor also includes a third unit to generate an instruction pointer pre-fetch (IPP) request for the predicted demand address. The processor may also include units to arbitrate between generated IP pre-fetch requests and alternative pre-fetch requests.
