Abstract
A translation look-aside buffer (TLB) has a TAG memory for determining if a desired translated address is stored in the TLB. A TAG portion is compared to contents of the TAG memory without requiring a read of the TAG memory because the TAG memory has a storage portion that is constructed as a CAM. For each row of the CAM a match determination is made that indicates if the TAG portion is the same as contents of the particular row. A decoder decodes an index portion and provides an output for each row. On a per row basis the output of the decoder is logically combined with the hit/miss signals to determine if there is a hit for the TAG memory. If there is a hit for the TAG memory, a translated address corresponding to the index portion of the address is then output as the selected translated address.
