Abstract: The present invention provides a method and apparatus for updating serial devices. The apparatus includes a plurality of serial registers. The apparatus further includes a device adapted to provide a signal and a plurality of parallel registers, wherein each of the parallel registers is adapted to access at least one of the plurality of serial registers at substantially the same time in response to detecting the signal.

Abstract: A method and apparatus for abandoning an interrupted task is provided. The method includes setting at least one of a plurality of logic elements associated with at least one of a plurality of first registers, wherein the plurality of first registers are adapted to access data stored in a plurality of second registers at substantially the same time when the plurality of logic elements are set. The method further includes resetting the plurality of logic elements substantially before the plurality of first registers access the data stored in the plurality of second registers.

Abstract: A method and apparatus for providing error isolation in a multi-domain computer system. The system includes a plurality of system resources allocated to form at least a first and second domain. The system resources of the first domain perform a set of transactions independent from a set of transactions performed by the system resources of the second domain. The system further comprises at least one interface for coupling one system resource from the first domain and one system resource from the second domain. The at least one interface tracks the set of transactions performed by the one system resource of the first domain and the one system resource of the second domain independently from one another.
