An InfiniBand™ Channel Adapter encrypts or decrypts user data on-the-fly. The user data is read from system memory and encrypted in by the Channel Adapter before sending it to a network. Similarly received data is decrypted on the fly before storing it in system memory. The encryption/decryption keys are preferably stored in a Queue Pair Context storage area of system memory as Public key for sending data and Private key for receiving data.

The present invention generally relates to digital network communication, and in particular to processing data according to the InfiniBand™ (IB) Protocol with reduced latency and chip costs in an InfiniBand™ type computer system. ID information in a packet header is obtained before the body of the packet has completely arrived at a receiving Channel adapter. The ID information is used to obtain work Queue Pair Context (QPC) and when needed an associated Work Queue Element (WQE), for operating on the data content of the packet being received.

A method for designing a circuit. The method includes (i) providing a netlist of a design and (ii) dividing the netlist into N user logics, N being a positive integer. After said dividing the netlist is performed, the N user logics in N macro test wrappers are instantiated resulting in N instantiated logics. After said instantiating the N user logics is performed, the N instantiated logics are processed. After said processing is performed, a result of said processing is back-annotated to the netlist.

The present invention relates to a method and respective system for operating a DRAM main memory. One buffer line is provided for multiple pages. When writing data to the buffer it is decided which to which buffer-line the data is written to based on its destination main memory address. A tuple consisting of lower memory address and data is stored. Data entered into the buffer-line will be sorted by page in case the line is flushed to the main memory. Sorting the buffer entries results in less page openings and closings, since the data is re-arranged by memory address and therefore in logical order. By using one line for multiple pages only a fraction of memory of a common set-associative cache is needed, thus decreasing the amount of overhead significantly.

A spectacle lens comprises a region (distance portion) designed for viewing at large distances and in particular “to infinity”; a region (near portion) designed for viewing at short distances and in particular “reading distances”; and a progressive zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at the near reference point located in the near portion along a curve (principal line) veering towards the nose. The invention is distinguished by a combination of the following features: a change of magnification with a direction of sight is small; the magnification increases radially, starting from the distance reference point; the difference between the magnifications at the distance and near reference points is small.

Described is a spectacle lens comprising a region (distance portion) designed for viewing at large distances and in particular “to infinity”; a region (near portion) designed for viewing at short distances and in particular “reading distances”; and a progressive zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at a near reference point located in the near portion along a curve (principal line) veering towards the nose. The invention is rendered distinct by a feature, amongst others, according to which trajectories of motion fulfill specific conditions.
摘要:
Described is a spectacle lens comprising a region (distance portion) designed for viewing at large distances and in particular “to infinity”, a region (near portion) designed for viewing at short distances and in particular “reading distances”, and a progressive zone disposed between the distance portion and the near portion, in which the power of the spectacle lens increases from a value at a distance reference point located in the distance portion to a value at the near reference point located in the near portion along a curve (principal line) veering towards the nose. The invention is distinct in that the astigmatic deviation, i.e. the difference between the prescribed and the actual astigmatism along circles having a center lying 4 mm below the centration point and having a diameter of 10 to 40 mm satisfies the following conditions: two local minima occur which on a “right-hand side spectacle lens” are located at 95°±10° (according to TABO) and at 280°±10°, and on a “left-hand side spectacle lens” at 85°±10° and 260°±10°; and two local maxima occur which on both a “right-hand side spectacle lens” and also a “left-hand-side spectacle lens” are located at 215°±10° and 335°±10°.

What is described here is a method of manufacturing spectacles comprising individual progressive ophthalmic lenses, including the following steps: selection of a spectacle frame, detection of the shape of the lens rings with a precision better than ±0.5 mm in the x- and y-directions (data set 1), detecting the intersection points of the lines of sight through the plane of the lens rings for at least two design distances of the progressive ophthalmic lenses with a precision better than ±1 mm (data set 2) selection and positioning relative to the lens rings of a spherical or non-spherical surface in view of the prescription data, using the data sets 1 and 2 (data set 3), computing and positioning the progressive surface relative to the selected surface, with minimization of the critical thickness of the ophthalmic lens, using the data sets 1 to 3 (data set 4), manufacturing the progressive surfaces as well as edges of the ophthalmic lenses from a non-edged semi-finished product finished on one side, using the data sets 1 to 4.
