An apparatus and method for low latency power management on a serial data link are described. In one embodiment, the method includes the detection of an electrical idle exit condition during receiver operation in an electrical idle state. Once detected, data synchronization is performed according to one or more received data synchronization training patterns. Finally, when the synchronization is performed within a determined synchronization re-establishment period, the receiver will resume operation according to a normal power state. Accordingly, the embodiment described illustrates an open loop, low latency power resumption operation for power management within 3GIO links.

A technique for bundling links is provided for increasing bandwidth and reducing latency. Two nodes in a network are configured to bundle two or more links connected between the two nodes. Data is transmitted between the two nodes by striping data over each link of the bundle. Data is transmitted in cells, and one or more cells are transmitted over each link of the bundle. The cells transmitted on one or more of the links include routing information.

In one embodiment, a processor includes a plurality of domains each to operate at an independently controllable voltage and frequency, a plurality of linear regulators each to receive a first voltage from an off-chip source and controllable to provide a regulated voltage to at least one of the plurality of domains, and a plurality of selectors each coupled to one of the domains, where each selector is configured to provide a regulated voltage from one of the linear regulators or a bypass voltage to a corresponding domain. Other embodiments are described and claimed.

A receiving device within a digital electronic system includes a sampling unit, a voter block, and a local clock phase adjustment unit. The sampling unit samples an input line at three points in time at intervals of one half of a bit period. The sampling unit delivers the values obtained in the sampling process to the voter block. The voter block determines whether to deliver an up or a down vote to the local clock phase adjustment unit. The voter block communicates with the local clock phase adjustment unit via up and down control signals. The local clock phase adjustment unit determines whether the local clock phase should be adjusted, and if so, whether to advance or delay the local clock phase. If certain meta-stable conditions are observed by the voter block, the voter block will vote in one direction in order to push the system out of the meta-stable condition.

Testing microelectronic devices using electro-optic modulator probes is disclosed. In one aspect, a testing apparatus may include an electrical signaling medium to exchange electrical signals with a microelectronic device. The testing apparatus may include an electro-optic modulator probe to provide optical signals that are modulated by the electrical signals. An optoelectronic transducer may be included to convert the modulated optical signals to modulated electrical signals. The testing apparatus may further include a logic analyzer module to receive and analyze the modulated electrical signals. Other testing apparatus are disclosed, as well as systems incorporating such apparatus, and various methods of testing microelectronic devices.
