  • MEMORY MAPPED FETCH-AHEAD CONTROL FOR DATA CACHE ACCESSES
    Publication number: 20130318307
    Abstract: An apparatus including a tag comparison logic and a fetch-ahead generation logic. The tag comparison logic may be configured to present a miss address in response to detecting a cache miss. The fetch-ahead generation logic may be configured to select between a plurality of predefined fetch ahead policies in response to a memory access request and generate one or more fetch addresses based upon the miss address and a selected fetch ahead policy.

  • Data structure caching for PDU re-generation and transmission in a 3G wireless network
    Patent number: 7738369
    Abstract: In one embodiment, a transmitter (a) caches one or more MAC-d PDUs received from a network layer, (b) selects a subset of the MAC-d PDUs for combination into a MAC-e PDU, (c) generates the MAC-e PDU from the subset of selected MAC-d PDUs, (d) caches a data structure to allow re-generation of the MAC-e PDU, wherein the re-generation does not rely on any cached copy of the MAC-e PDU, (e) transmits the MAC-e PDU for receipt by a receiver; and (f) determines whether an ACK was received, wherein if an ACK was not received, then the MAC-e PDU is re-generated using the cached data structure and the subset of selected MAC-d PDUs, and steps (e) and (f) are repeated, and if an ACK was received, then the memories used to cache the data structure and the first subset of MAC-d PDUs are freed.
