  • Patent number: 5479629
    Abstract: Duplicate translations resulting from multiple requests for address translations from a plurality of address generators are eliminated by the addition of a DLAT address buffer. If the address requested is a hit in the DLAT, the translation is handled in the conventional manner. If there is a miss, the address is put into the DLAT address buffer. Future requests from other address generators are compared with the addresses in the DLAT address buffer to see if there is an outstanding request for this address. If not, the addresses are also entered into the buffer. If there is an outstanding request, the requestor is marked in an address distributor as wanting the address. When the translation is returned from the BCE, the address is sent to all requestors wanting the address, to the DLAT and to the buffer for deletion from the buffer.
