Abstract
A method for implementing a graphics address remapping table as a virtual register in system memory. The remapping table includes virtual registers that each store a target index that references a block of the system memory that stores graphics data. The method uses an indirect addressing scheme that enables the individual virtual registers of the remapping table to be accessed in response to a transaction request. Accessing a selected virtual register indirectly requested by the transaction request enables the method to access graphics data pointed to by the selected virtual register.
