Abstract
In a data processing system having a main store addressed by system addresses and a buffer addressed by logical addresses, where more than one logical address may map to a single system address, a translation buffer is adapted to provide a means for linking translation buffer locations that may map to a given system address to identify all synonym logical addresses. The implementation includes a list header table that generates a pointer to the translation buffer in response to a system address. A search of the translation buffer beginning at the location identified by the list header table and proceeding through each linked location is carried out to identify all synonym logical addresses. The synonym logical addresses are associated by an exclusive ordered list and a means is provided for updating the exclusive list when new entries are made in the translation buffer or old entries are deleted.
