  • Systems and methods for accessing bus-mastered system resources
    Patent number: 7039736
    Abstract: Disclosed are systems and methods for providing access to bus-mastered system resources comprising disposing a bus multiplexer between a first bus and a bus access arbiter, wherein the first bus is coupled to at least one system resource for which bus access is arbitrated by the bus access arbiter, and controlling the bus multiplexer to couple a second bus to the first bus thereby providing a link between the first bus and the second bus bypassing the bus access arbiter.
    Type: Grant

  • Apparatus and method for verification of system interconnect upon hot-plugging of electronic field replaceable units
    Patent number: 6901344
    Abstract: A field unit has a connector with first and second interconnect apparatus coupled to connector. The field replaceable unit has test apparatus coupled to the first and second interconnect apparatus capable of testing connections through the connector to the first interconnect apparatus under control of signals on the second interconnect apparatus. The field replaceable unit is capable of being hot-plugged. In an embodiment, the second interconnect apparatus is of the JTAG type. Also claimed is a method of testing interconnect between the field replaceable unit and another unit of a system into which it has been hot-plugged.
