... SBA port (to send addresses unmultiplexed). AGP masters implement one or the other or select one at initialization time (they are not allowed to change during runtime). Therefore only one of the two will be used and the signals associated with the other will not be used. Therefore the VT8363A has an internal pullup on GRBF# to maintain it in the de-asserted state in case it is not implemented on the master device. ...

... Since address translation using the above scheme requires an access to system memory, an on-chip cache (called a "Translation Lookaside Buffer" or TLB) is utilized to enhance performance. The TLB in the VT8363A contains 16 entries. Address "misses" in the TLB require an access of system memory to retrieve translation data. Entries in the TLB are replaced using an LRU (Least Recently Used) algorithm ...
