摘要:
Described herein are embodiments of an apparatus configured for dynamic link width modulation, a system including an apparatus configured for dynamic link width modulation, a method for dynamic link width modulation, and computer-readable media having instructions that, if executed by one or more processors, cause an apparatus to perform a dynamic link width modulation method. An apparatus configured for dynamic link width modulation may include a first counter for determining a length of a queue of packets at a source of a link, a second counter for determining a rate of utilization of the link, and a power control unit configured to modify a width of the link based at least in part on the length of the queue and the rate of utilization. Other embodiments may be described and/or claimed.

Mechanisms for exposing a protected memory address are provided. A processing device may store a data value at a protected memory address. The protected memory address may be a control register or a status register. The processing device may identify a mirror relationship between the protected memory address and an unprotected memory address and copy the data value from the protected memory address to the unprotected memory address. The unprotected memory address may be directly accessible via an external interface.

A method and system to improve the operations of a registered memory module. In one embodiment of the invention, the registered memory module allows asynchronous read and write operations when a clock circuit in the registered memory module is being activated. In another embodiment of the invention, the registered memory module allows enabling or disabling of its clock circuit without any interruption of its operation. When the clock circuit in the registered memory module is disabled, the power consumption of the registered memory module can be reduced. In yet another embodiment of the invention, the registered memory module is allowed to enter or exit an asynchronous operation mode without entering or exiting a self-refresh or pre-charge power down operation mode of the registered memory module.

Described herein are techniques for dynamic memory frequency/voltage scaling to augment existing memory power management techniques and further improve memory power efficiency. Each operating point is defined as an operational state for the memory.

A memory controller uses a scheme to retire two entries from a replay queue due to a single non-error response. Advantageously, entries in a replay queue may be retired earlier than conventional systems, minimizing the size of the replay queue.

Embodiments of the invention are generally directed to systems, methods, and apparatuses for rank coordination. In some embodiments, a host includes rank coordination logic. The rank coordination logic may include performance measurement logic to measure a performance of a memory channel and dwell period control logic to select a length of a dwell period based, at least in part, on the performance of the memory channel. Other embodiments are described and claimed.

Embodiments of the invention are generally directed to systems, methods, and apparatuses for chipset determinism to improve validation. In some embodiments, an integrated circuit synchronously receives one or more requests from a processor interconnect, exchanges the requests across an asynchronous interface, and releases a corresponding one or more responses to the processor interconnect on synchronous, deterministic time boundaries with respect to a specified deterministic event.
