摘要： A loopback test to test a communication link for a layered interface where in a master agent programs the electrical parameters for the slave agent, such as, the offset, timing, and current compensation with a loopback control register. The slave agent's transmitter and receiver are independently controlled and the master agent may use a slave-echoed data test pattern to detect errors and subsequently sets the appropriate status bits in a loop back status register

摘要： A loopback test to test a communication link for a layered interface where in a master agent programs the electrical parameters for the slave agent, such as, the offset, timing, and current compensation with a loopback control register. The slave and master agent to support an entry into the loopback test based on detection of a header within a packet. The slave and master agent to support exit out of the loopback test based on whether the loop count is finite.

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： Disclosed are embodiments of a method, apparatus and system for a low power state for a point-to-point link. During the low power state, the signal on both conductors of a differential transmit pair are driven to electrical idle. Analog activity detectors are enabled during the low power state and are disabled during normal power state. Exit from the low power state does not require a physical layer re-initialization sequence. Other embodiments are also described and claimed.

摘要： Embodiments of the invention provide an algorithm for dividing a link into one or more reduced-width links. For one embodiment of the invention, a multiplexing scheme is employed to effect a bit transmission order required by a particular cyclic redundancy check. The multiplexed output bits are then swizzled on-chip to reduce on-board routing congestion.
