Abstract
Provided are systems and methods for an address translation circuit for a memory controller. In various implementations, the address translation circuit includes an address translation table operable to include a subset of address translations for a processor memory. An address translation memory can include all address translations for the processor memory. The address translation circuit can be operable to receive an input address for a transaction to processor memory. The address translation circuit can determine an index for the address translation table by inputting the input address into a hash function. The address translation circuit can read a row from the address translation table using the index. The address translation circuit can determine whether an entry in the row includes an address translation for the input address. The address translation can generate and output a translated address using the address translation.
