摘要:
The present invention provides a method, apparatus, and system for dynamically changing the sizes of power-control pools that are used to control the power consumption levels of memory devices. In one embodiment, a request to change the sizes of the memory power-control pools is received. In response to receiving the request to change the sizes of the memory power-control pools, the memory devices are placed in a specific operating mode or power state after being refreshed in a periodic refresh cycle. In response to a signal indicating that all memory devices have been placed in the specific operating mode, powercontrol pools are resized according to pool size values corresponding to the request received.

A bus architecture arrangement is provided. Embodiments provide for a point-to-point protocol of a bused system, such as a processor-based system. Further embodiments may comprise a dynamically configurable point-to-point communication array with connectors and/or translators to couple hub devices with endpoint devices. Some of the connectors and/or translators may inductively or magnetically couple endpoint devices to and decouple endpoint devices from point-to-point communication media to facilitate efficient use of a point-to-point communication array.

A RDRAM memory controller is provided to couple to a channel that is further coupled to a first RDRAM device and a second RDRAM device. The memory controller may include a command queue to store a plurality of commands and scheduling logic to schedule the plurality of commands to shift from the command queue based on a clock signal. Delaying logic may be provided to delay at least one command after the command shifts from the command queue. The delaying logic may include a plurality of multiplexors and a delay register coupled to outputs of the command queue.

A circuit comprising a first register and a second register to store the first and second status of the plurality of memory banks. Also, the circuit comprises a logic and an encoder circuit. The logic is coupled to the first and second registers and generates a third status of the plurality of memory banks based on the first and second status. The encoder coupled to the logic generates a refresh request in response to the third status of the plurality of memory banks.

A method and apparatus of enforcing a connection policy of a system controller is disclosed. In one embodiment, the method and apparatus monitor multiple distinct device identifications on a bus connected to the system controller. When more than a threshold number of the device identifications have been identified on the bus, the method and apparatus proceed to disable the system controller.

An information capturing technique captures information on a processor cycle that results in a high level interrupt, such as an SMI (System Management Interrupt). A memory controller is connected to at least one processor to control a memory in response to instructions from the at least one processor. An I/O controller is connected to the memory controller to control data flow to at least one device in response to instructions from the at least one processor. Lock down logic stores captured cycle information on a processor cycle that results in interrupt.

摘要:
A method, apparatus, system, and machine-readable medium to bound data transmission latency by transmitting error verification data at a point during a data transmission based upon loading of a channel for the data transmission is provided. Embodiments may comprise determining the loading of a communication channel and transmitting error verification data to a target device based upon the loading. More specifically, some embodiments transmit error verification data at intervals, variable intervals in some embodiments, to balance transmission latency against the bandwidth available from a communication medium.

A method, apparatus, system, and machine-readable medium to bound data transmission latency by transmitting error verification data at a point during a data transmission related to a data transmission event is provided. Embodiments may comprise receiving an indication of a data transmission event, such as an end of a packet, and transmitting error verification data to a target device based upon the indication. More specifically, some embodiments transmit error verification data at an end of a packet to balance transmission latency against the bandwidth available from a communication medium.
