An air conditioning cooling apparatus and method which includes the steps of supplying cooling air generated from a cooling apparatus into an air passageway formed below a floor; guiding the cooling air within the air passageway into an equipment assembly disposed on the floor through an opening located in the floor; communicating the cooling air introduced into the equipment assembly into a plenum and introducing the air released from within the equipment into the plenum and communicating the released air through the cooling apparatus for cooling the released air. The method permits temperature differential between the air supplied to the air passageway and the air introduced into the plenum from the equipment assembly to be 45.degree. F. to substantially 40.degree. F. so as to reduce the power necessary for operating on the fan of the blowing apparatus. The equipment assembly utilizes an air flow control mechanism so as to substantially evenly distribute cooling air to the equipment.

Described is a system and method for monitoring a mobile computing Arrangement. The arrangement may include a sensor and a processor. The sensor detects first data of an event including a directional orientation and a motion of the arrangement. The processor compares the first data to second data to determine if at least one predetermined procedure is to be executed. The second data may include a predetermined threshold range of changes in the directional orientation and the motion. If the predetermined procedure is to be executed, the processor selects the predetermined procedure which corresponds to the event as a function of the first data. Subsequently, the predetermined procedures is executed.

Various methods and apparatus to support outstanding requests to multiple targets while maintaining transaction ordering
ActiveUS20080320476A1Digital computer detailsMultiprogramming arrangementsIntellectual propertyOrder form
A method, apparatus, and system are described, which generally relate to an integrated circuit having an interconnect that implements internal controls. The interconnect in an integrated circuit communicates transactions between initiator Intellectual Property (IP) cores and target IP cores coupled to the interconnect. The interconnect implements logic configured to support multiple transactions issued from a first initiator IP core to the multiple target IP cores while maintaining an expected execution order within the transactions. The logic supports a second transaction to be issued from the first initiator IP core to a second target IP core before a first transaction issued from the same first initiator IP core to a first target IP core has completed while ensuring that the first transaction completes before the second transaction and while ensuring an expected execution order within the first transaction and second transaction are maintained. The logic does not include any reorder buffering.

This abstract has been included pursuant to Section 1.72(b) of the Rules for Patent and Trademark Cases, Title 37 of the Code of Federal Regulations. This abstract is intended only to enable the Patent and Trademark Office and the public to generally determine the nature of the technical disclosure. This abstract is not intended to aid in the interpretation of the scope of any claim. A portable computing device includes a keyboard controller that receives keystroke information as well as inputs from a graphical pointing device and conveys these to a main central processing unit. The keyboard controller additionally communicates with a battery module through a second interface in order to monitor and control the charging of the module. A low power secondary processor is interfaced to the keyboard controller through the second interface in order to receive keystroke information as well as information from the graphical pointing device. When the keyboard controller is instructed to do so, keystroke and graphical pointing information are conveyed exclusively to the secondary processor, thereby enabling the portable computing device to perform some functions without requiring the main central processing unit to be operational and thus operate in a low power mode.

Various methods and apparatus to support transactions whose data address sequence within that transaction crosses an interleaved channel address boundary
ActiveUS20080320254A1Memory adressing/allocation/relocationDigital computer detailsEmbedded systemAddress space
A method, apparatus, and system are described, which generally relate to an interconnect routing transactions to target IP cores, including two or more channels making up a first aggregate target. The two or more channels populate an address space assigned to the first aggregate target and appear as a single target to the initiator IP cores. The interconnect implements chopping logic to chop an individual transaction from a first initiator IP core whose address sequence crosses a channel address boundary from a first channel to a second channel within the first aggregate target into two or more burst transactions. A first chopped burst transaction is chopped to fit within the address boundaries of the first channel and a second chopped burst transaction is chopped to fit within the address boundaries of the second channel.

Dynamic Converter Control for Efficient Operation
ActiveUS20080320322A1Electric signal transmission systemsBatteries circuit arrangementsDynamic managementPower consumption
Dynamically managing power consumption in a computer system having at least two parallel power converters in order to improve efficiency. A maximum power capacity for each of the power converters is determined and then power consumption of the computer system is monitored. If the power consumption of the computer system can be provided by less than all of the parallel power converters then one or more of the power converters is turned off, such that a reduced number of parallel power converters remains turned on. A reduced maximum power capacity of the reduced number of parallel power converters is determined and a power cap value is set for the computer system that is less than or equal to the reduced maximum power capacity. The computer system is throttled at the power cap to prevent power consumption of the computer system from exceeding the power cap value.

An object of the invention is to reduce the electric power consumption resulting from temporarily activating a processor requiring a large electric power consumption, out of a plurality of processors. A multiprocessor system (1) includes: a first processor (141) which executes a first instruction code; a second processor (151) which executes a second instruction code, a hypervisor (130) which converts the second instruction code into an instruction code executable by the first processor (141); and a power control circuit (170) which controls the operation of at least one of the first processor (141) and the second processor (151). When the operation of the second processor (151) is suppressed by the power control circuit (170), the hypervisor (130) converts the second instruction code into the instruction code executable by the first processor (141), and the first processor (141) executes the converted instruction code.

A disk drive group 1 and a control circuit board group 2 constituting electrical loads are respectively connected to the power supply common bus 7. When the supply of power from the main power supply stops, the capacitor box 3 supplies a relatively large current for a short time only, in order to retain data during an instantaneous power outage. Then, the battery boxes 4 supply power to the power supply common bus 7 for a relatively long period of time, in order to perform destage control and memory backup. The battery boxes 4 perform balancing control of the output current in order to suppress variation in the output current value among the battery boxes 4.
