Abstract:
A device for multi-stage translation of prefetch requests includes a prefetch queue for providing queued prefetch requests, each of the queued prefetch requests including N different control entries; N serial-connected translation stages for the translation of N control entries of one of the queued prefetch requests into a translated prefetch request, wherein a translation in a i-th translation stage is dependent on a translation in a (i−1)-th translation stage, iε[1, . . . , N]; and a prefetch issuer which is configured to control an index for each of the N different control entries in the prefetch queue and to issue a prefetch of the indexed control entry of the N different control entries for the highest non-stalled translation stage.
