Abstract
Methods and systems are disclosed for recovering dirty linefill buffer data upon linefill request failures. When a linefill request failure occurs and the linefill buffer has been marked as dirty, such as due to a system bus failure, the contents of the linefill buffer are pushed back to the system bus. The dirty data within the linefill buffer can then be used to update the external memory. The disclosed embodiments are useful for a wide variety of applications, including those requiring low data failure rates.
