A remote device monitoring system including a host server including at least a processor, system bus, user input interface configured to communicate with a user input device, display interface configured to communicate with a display, network interface configured to communicate with at least one remote device and at least one data storage means including a database, a performance look-up table and at least one analyzer module including program instructions that, when implemented by the processor, receive at least one performance parameter value from at least one remote device and query the performance look-up table.

The present invention provides a motherboard that uses a high-speed, scalable system bus such as PCI Express® to support two or more high bandwidth graphics slots, each capable of supporting an off-the-shelf video controller. The lanes from the motherboard chipset may be directly routed to two or more graphics slots. For instance, the chipset may route (1) thirty-two lanes into two ×16 graphics slots; (2) twenty-four lanes into one ×16 graphics slot and one ×8 graphics slot (the ×8 slot using the same physical connector as a ×16 graphics slot but with only eight active lanes); or (3) sixteen lanes into two ×8 graphics slots (again, physically similar to a ×16 graphics slot but with only eight active lanes). Alternatively, a switch can convert sixteen lanes coming from the chipset root complex into two ×16 links that connect to two ×16 graphics slots. Each and every embodiment of the present invention is agnostic to a specific chipset.

A PCI Express-compatible flash device can include one or more flash memory modules, a controller, and an ExpressCard interface. The controller can advantageously provide PCI Express functionality as well as flash memory operations, e.g. writing, reading, or erasing, using the ExpressCard interface. A PIO interface includes sending first and second memory request packets to the flash device. The first memory request packet includes a command word setting that prepares the flash device for the desired operation. The second memory request packet triggers the operation and includes a data payload, if needed. A DMA interface includes sending the second memory request from the flash device to the host, thereby triggering the host to release the system bus for the DMA operation.

A thin flat panel display for aircraft cockpits. These displays use a dual CPU/graphics generator system to produce simulated aircraft instrumentation displays which are color coded to indicate when one of the graphic generators has not correctly received data from the aircraft system bus. The displays use standard graphic generators and CPUs, and do not require additional software. The displays also allow the aircraft systems to be continuously tested while the aircraft is on the ground. Moreover, the inventive systems include input touch devices which access external memories to display necessary flight and landing information which allow the cockpit crew to expand in detail the external information for display on the flat panels.

A very small computer memory card is densely packed with a large number of flash EEPROM integrated circuit chips. A computer memory system provides for the ability to removably connect one or more of such cards with a common controller circuit that interfaces between the memory cards and a standard computer system bus.

An electronic system is described for a memory system and its controller within a single memory card. In a preferred physical arrangement, the cards utilize a main circuit board with a plurality of sub-boards attached thereto on both sides, each sub-board carrying several integrated circuit chips.

A method and apparatus for sharing memory in a multiprocessor computing system. More specifically, this invention provides a number of system buses with each bus being connected to a respective memory controller which controls a corresponding partition of the memory. Any one of the processors can use any one of the system buses to send real addresses to the connected memory controller which then converts the real addresses into physical addresses corresponding to the partition of memory that is controlled by the receiving memory controller. The processors can be dynamically assigned to different partitions of the memory by via a switching mechanism.

IPSec processing is performed at the acceleration device without sending the IP Packet to system memory for processing.

There is described a method, a bus protocol, a peripheral module, a processing unit, a hub and also to a system consisting of said components, for event signaling between at least one peripheral module and a processing unit by means of a system bus. In this case the data to be transmitted data is encoded into a larger symbol space, from which a standard idle symbol is used in telegram pauses for synchronizing a connection between transmitter and receiver. A message present at the peripheral modules is enabled to be signaled to the processing unit independently of the telegram traffic initiated by the processing unit. This is achieved by a peripheral module wishing to signal an event to the processing unit sending to the processing unit in a telegram pause, instead of the standard idle character, a signaling sequence consisting of an alarm idle symbol and an alarm identifier which contain information about the relevant event as well as the module address of the peripheral module at which the event is present, with the information about the event also being transcoded into the larger symbol space.

A memory module includes a memory hub that monitors utilization of the memory module and directs devices of the memory module to a reduced power state when the module is not being used at a desired level. System utilization of the memory module is monitored by tracking system usage, manifested by read and write commands issued to the memory module, or by measuring temperature changes indicating a level of device activity beyond normal refresh activity. Alternatively, measured activity levels can be transmitted over a system bus to a centralized power management controller which, responsive to the activity level packets transmitted by remote memory modules, direct devices of those remote memory modules to a reduced power state. The centralized power management controller could be disposed on a master memory module or in a memory or system controller.

A voltage control arrangement for a system of multiple windfarms with transmission lines. Voltage is regulated at a point of regulation on the system, such as a high voltage substation or other system bus. Regulation is achieved at the point of regulation by sensing the voltage, comparing to a reference voltage, and adjusting the reactive power output of the wind turbines and other equipment in the system. The regulation point may be shifted to another point if needed to respect voltage limits at that points of the system after attempting to shift reactive load to restore voltage within limits at the other points in the system. The reference voltage may be adjusted to minimize losses for the system of multiple windfarms and transmission lines. A loss optimizing algorithm is applied to the combined multiple windfarm and transmission line to shift reactive load among local windfarms to minimize losses and to shift reactive load among individual wind turbines within an individual windfarm.

The collection of such switching elements and latches are provided on a single silicon chip which includes of the functions of the invention.

Systems and methods for network transmission of three-dimensional graphical data are disclosed. A single graphical application instance can virtually and efficiently exist on multiple local or remote display systems by directly sharing its raw rendered framebuffer memory information among all local or remote graphics accelerators, thus avoiding the need to re-render any application information again on each node. An internal graphics card is used to scale the rendered data prior to transmission. This graphics scaling eliminates the need for data compression or image compression and achieves an adaptive, hardware-accelerated reduction in network bandwidth. Furthermore, since all memory and remote processing support tasks are performed within the graphics card, the CPU, system bus, and memory bandwidth remain available to the system and other applications.

The system plug and the auxiliary system connector are interconnected by a system bus that extends through the base.

Described is a data processing system and processor that provides full multiprocessor speculation by which all instructions subsequent to barrier operations in a instruction sequence are speculatively executed before the barrier operation completes on the system bus. The processor comprises a load/store unit (LSU) with a barrier operation (BOP) controller that permits load instructions subsequent to syncs in an instruction sequence to be speculatively issued prior to the return of the sync acknowledgment. Data returned is immediately forwarded to the processor's execution units. The returned data and results of subsequent operations are held temporarily in rename registers. A multiprocessor speculation flag is set in the corresponding rename registers to indicate that the value is “barrier” speculative. When a barrier acknowledge is received by the BOP controller, the flag(s) of the corresponding rename register(s) are reset.

An computer program product and a method is presented for diagnosing hardware and software problems on a network computer through the use of a diagnostic adapter card. The diagnostic adapter card is installed in an open slot in the system bus and thus has access to all the network computer electronics and peripherals. Diagnostic programs are run and the results are logged. By analyzing these results, the source of the problem can be determined and reported for service or repair. The diagnostic adapter card contains its own processor, read only memory, random access memory, and interface logic for connecting to the system bus, a set of external wrap cables for peripheral connector testing, and an external reporting device. Some tests require use of a wrap cable to connect two or more ports together. Other tests, such as system bus timing or memory integrity, do not require the use of wrap cables.

A distributed direct memory access (DMA) method, apparatus, and system is provided within a system on chip (SOC). DMA controller units are distributed to various functional modules desiring direct memory access. The functional modules interface to a systems bus over which the direct memory access occurs. A global buffer memory, to which the direct memory access is desired, is coupled to the system bus. Bus arbitrators are utilized to arbitrate which functional modules have access to the system bus to perform the direct memory access. Once a functional module is selected by the bus arbitrator to have access to the system bus, it can establish a DMA routine with the global buffer memory.
