    摘要: A memory subsystem includes a test signal generator of a memory controller that generates a test data signal in response to the memory controller receiving a test transaction. The test transaction indicates one or more I/O operations to perform on an associated memory device. The test signal generator can generate data signals from various different pattern generators. The memory controller scheduler schedules the test data signal pattern, and sends it to the memory device. The memory device can then execute I/O operation(s) to implement the test transaction. The memory controller can read back data written to a specific address of the memory device and compare the read back data with expected data. When the read back data and the expected data do not match, the memory controller can record an error. The error can include the specific address of the error, the specific data, and/or encoded data.

    摘要: The present invention is a method and apparatus for virtualizing a serial bus information source/sink point of a serial bus device into an address space of a processor. A register unit is coupled to a parallel port device to support a serial bus transaction between the processor and the serial bus device. The register unit has a plurality of registers which are mapped into the address space of the processor via the parallel port device. One of the plurality of registers corresponding to the serial bus information source/sink point. A control circuit is coupled to the register unit to allow the processor to access the information source/sink point via the parallel port device.

    摘要: An Ethernet interface device, and associated system and method, for reporting the status information data of Ethernet devices through common industrial protocols. The Ethernet interface device provides operational connections between one or more Ethernet devices and one or more independent networks. The Ethernet interface device also monitors an Ethernet connection path, and produces status data indicative of the operational status of the connection path and the devices connected along the path. This status data is received by the Ethernet interface device, where it is manipulated into a format recognizable by common industrial protocols.

    摘要: The present invention is directed to a method and apparatus for converting between serial bus cycles and parallel port commands. A serial bus processor processes a serial bus transaction which is represented by the serial bus cycles and is responsive to the parallel port commands. A state machine circuit is coupled to the serial bus processor to provide a plurality of states corresponding to the serial bus transaction. The state machine circuit transitions from one of the states to any one of the states in response to a change condition asserted by a state signal.
