Patent number: 7657728Abstract: Systems and methods are disclosed for maintaining an accurate program-visible machine state of a computer. A backup system and method is provided in order to return the visual state of the computer to a previous state if an instruction generates an exception. In an embodiment, a first tag and a second tag are received from a tag queue concurrently. First data, which is associated with the first tag, is received and stored in a first register associated with the first tag. Second data, which is associated with the second tag, is sent from a second register associated with the second tag to a backup queue.Type: GrantFiled: June 11, 2008Date of Patent: February 2, 2010Assignee: Seiko Epson CorporationInventor: Anders R. Johnson

Publication number: 20090024841Abstract: A register file backup system for use with a computer which processes instructions to generate results which thereby change the visual state of the computer. The computer has a register file with a plurality of addressable locations for storing data. The backup system is adapted to return the visual state of the computer to a previous state if an instruction generates an exception. The backup system utilizes less overhead so as to provide easier register file backup than a comparable software or hardware device. The backup system comprises first means for sequentially storing in program order, address information corresponding to destination locations in the register file where instruction results are to be stored.Type: ApplicationFiled: June 11, 2008Publication date: January 22, 2009Applicant: SEIKO EPSON CORPORATIONInventor: Anders R.
