摘要:
A three dimensional electronic module is disclosed. Conventional TSOP packages are modified to expose internal lead frame interconnects, thinned and stacked on a reroute substrate. The reroute substrate comprises conductive circuitry for the input and output of electrical signals from one or more TSOPs in the stack to a ball grid array pattern. The exposed internal lead frames are interconnected and routed on one or more side buses on the module to the reroute substrate for connection to external electronic circuitry. Alternatively, internal wire bonds or ball bonds may be exposed in the TSOP packages and routed to the side bus for interconnection to create a BGA scale module. One or more neolayers may also be bonded to a reroute substrate to create a BGA scale module.

The present invention provides a system, method, and computer program product that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for handling user space query and modification operations for querying and modifying attributes of allocations of linear block addresses of a physical storage device. For modification, it is determined if there are sufficient available resources for the modification of the allocation. In addition, it is determined if there are any I/O transactions active on the allocation before performing the modification. Modification of the attributes of the allocation may be performed only if there are sufficient available resources and only if there are no active I/O transactions on the allocation being modified.

The present invention provides a system, method, and computer program product that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for handling user space creation and deletion operations for creating and deleting allocations of linear block addresses of a physical storage device to application instances. For creation, it is determined if there are sufficient available resources for creation of the allocation. For deletion, it is determined if there are any I/O transactions active on the allocation before performing the deletion. Allocation may be performed only if there are sufficient available resources and deletion may be performed only if there are no active I/O transactions on the allocation being deleted.
摘要:
A mechanism for offloading the management of receive queues in a split (e.g. split socket, split iSCSI, split DAFS) stack environment, including efficient queue flow control and TCP/IP retransmission support. An Upper Layer Protocol (ULP) creates receive work queues and completion queues that are utilized by an Internet Protocol Suite Offload Engine (IPSOE) and the ULP to transfer information and carry out send operations. As consumers initiate receive operations, receive work queue entries (RWQEs) are created by the ULP and written to the receive work queue (RWQ). The ISPOE is notified of a new entry to the RWQ and it subsequently reads this entry that contains pointers to the data that is to be received. After the data is received, the IPSOE creates a completion queue entry (CQE) that is written into the completion queue (CQ). After the CQE is written, the ULP subsequently processes the entry and removes it from the CQE, freeing up a space in both the RWQ and CQ. The number of entries available in the RWQ are monitored by the ULP so that it does not overwrite any valid entries. Likewise, the IPSOE monitors the number of entries available in the CQ, so as not overwrite the CQ.

A semiconductor device comprising a metallic leadframe (103) with a first surface (103a) and a second surface (103b). The leadframe includes a chip pad (104) and a plurality of segments (107); the chip pad is held by a plurality of straps (105), wherein each strap has a groove (106). A chip (101) is mounted on the chip pad and electrically connected to the segments. A heat spreader (110) is disposed on the first surface of the leadframe; the heat spreader has its central portion (110a) spaced above the chip connections (108), and also has positioning members (110b) extending outwardly from the edges of the central portion so that they rest in the grooves of the straps. Encapsulation material surrounds the chip, the electrical connections, and the spreader positioning members, and fills the space between the spreader and the chip, while leaving the second leadframe surface and the central spreader portion exposed.

An integrated circuit (IC) package 100 comprises an IC 102 and leads 104 coupled to the IC. Each lead has a first end 106 configured to be coupled to the integrated circuit and a second end 108 configured to pass through one of a plurality of mounting holes 110 extending through a mounting board 112. The leads comprise at least one positioning lead 114 comprising a stop 118 being a continuous part of the positioning lead and having a lateral dimension 120 greater than a diameter 122 of a first hole 124 of the plurality of mounting holes. The leads further comprise at least one non-positioning lead 116 having a continuous uniformly shaped body 130 with a lateral dimension 132 less than a diameter 134 of a second hole 136 of the plurality of mounting holes. The stop limits an extension of the non-positioning lead through the second hole.

A method for assembling a whole semiconductor wafer (101) with a plurality of device units (120) having metal contact pads. Each contact pad has a patterned barrier metal layer and a metal stud (103, preferably copper or nickel) with an outer surface suitable to form metallurgical bonds without melting. A leadframe suitable for the whole wafer is provided, which has a plurality of segments groups (102), each group suitable for one device unit; each segment has first (102a) and second ends (102b) covered by solderable metal. A predetermined amount of solder paste (104) is placed on each of the first segment ends. The leadframe is then aligned with the wafer so that each of the paste-covered segment ends is aligned with the corresponding metal stud of the respective device unit. The leadframe is connected to the wafer and the whole wafer is encapsulated (105) so that the device units and the first segment ends are covered, while the second segment ends remain exposed. The encapsulated wafer is separated (110) into individual device units (120).
摘要:
A lifting and carrying apparatus for vehicles such as all-terrain vehicles, which apparatus includes a typically wheeled lift frame hingedly attached to the bottom ends of a pair of parallel, downwardly-extending frame legs connected at the opposite ends by a spacer bar. A fixed frame mount slidably receives the frame legs for up and down lift frame travel and the frame mount is mounted on a receiver bracket fitted with a winch and a roller positioned forwardly of the winch. The receiver bracket is fixed to the frame of an all-terrain vehicle to facilitate raising and lowering the lift frame and the frame legs in the frame mount using a lift line or strap attached to the lift frame and extending over the roller to the winch, and operating the winch. The lift frame can also be folded adjacent to the frame legs by either repositioning the lift strap to the extremity of the lift frame and operating the winch to close the lift frame on the frame legs or pivoting the lift frame by hand into the folded configuration against the frame legs. The roller and the winch can be interchanged in the receiver bracket to facilitate low profile storage of the folded lifting and carrying apparatus when it is not in use.
