    摘要: A software self test engine is executed from a cache of a processor. The software self test engine is executed using an execution engine of the processor to perform a physical layer self test. The physical layer self test is performed by transmitting a test vector from the execution engine under control of the self test engine to an input/output (“I/O”) unit of the processor along a datapath coupling the execution engine to the I/O unit. The test vector is transmitted along a loop back path including the I/O unit and the datapath to test a hardware device along the loop back path.

    摘要: In some embodiments, clock strobed data over one waveguide or fiber is presented. In this regard, a transfer agent is introduced to convert one or more lanes of data and a corresponding clock strobe from electrical signals to optical signals of differing wavelengths. Other embodiments are also disclosed and claimed.

    摘要: A method and apparatus for advancing initialization messages in a lock-step manner when initializing an interface is presented. In one embodiment, a lane receiver may transition to a receiver ready attribute when a given number of current training sequence messages is correctly received. When the receiver ready attributes of all the lanes are set, a local acknowledgement attribute may be set. Similarly, a lane receiver may transition to a remote acknowledgement attribute when a given number of current training sequence messages with acknowledgement field set is correctly received. When both the local acknowledgement attribute and the remote acknowledgement attribute are set, the port may advance to the next training sequence messages.
