A computer data signal embodied in a propagation medium is provided. The signal enables a variable number of data transfers and includes an initial connection source code segment and a data transfer source code segment. The initial connection source code segment establishes a connection between at least two devices via predetermined listening ports, with at least one predetermined listening port residing within each device. The initial connection source code segment also dynamically assigns a first data port within a first device, and transmits the address of the first data port to a remaining device via the predetermined listening ports. The data transfer source code segment is for each of the variable number of data transfer operations. The data transfer source code segment dynamically assigns a corresponding second data port within the remaining device and transfers data between the connected devices via the data ports so that the data is substantially simultaneously transferred between a variable number of devices via the data ports. Each pair of first and second data ports is established in response to each listening port connection.

An adaptive replacement cache policy dynamically maintains two lists of pages, a recency list and a frequency list, in addition to a cache directory. The policy keeps these two lists to roughly the same size, the cache size c. Together, the two lists remember twice the number of pages that would fit in the cache. At any time, the policy selects a variable number of the most recent pages to exclude from the two lists. The policy adaptively decides in response to an evolving workload how many top pages from each list to maintain in the cache at any given time. It achieves such online, on-the-fly adaptation by using a learning rule that allows the policy to track a workload quickly and effectively. This allows the policy to balance between recency and frequency in an online and self-tuning fashion, in response to evolving and possibly changing access patterns. The policy is also scan-resistant. It allows one-time-only sequential read requests to pass through the cache without flushing pages that have temporal locality. The policy is extremely simple to implement and requires only constant-time overhead per request. The policy has negligible space overhead.

A computer system provides an improved graphical user interface by defining a view space in which graphical user interface windows from separate computer processes can be selectively located by a user. This view space has a plurality of discrete portions each large enough to hold a plurality of such user interface windows. The system enables users to selectively associate view space portions with physical locations external to the system's computing apparatus. The system also enables users to selectively locate a variable number of the user interface windows in each of the view space portions associated with such a physical location, including enabling the user to selectively move windows between such view space portions. The system detects when a user motions toward a given physical locations and responds to such a detection by presenting a visual display showing the given view space portion associated with the given physical location, together with any user interface window located in the given view space portion. In some versions of the invention, the physical location can be defined by a global positioning system and the system can detect when a user moves into a location defined by such global positioning.

A pop-up toolbar is disclosed which is demonstrably faster and easier to utilize than the permanently displayed, horizontal toolbar. Two columns provide a variable number of irregularly shaped regions arrayed on either side of a generally circular central-area. Components of regions converge on the central area. Targets, each displaying an icon and an optional, descriptive label, appear within the regions. At pop-up of the toolbar, the cursor moves under system control to the central-area of the toolbar, enabling users to perform short, radial traverses of the cursor into targets, activating related functions by appropriate action. Alternatively, primary and secondary targets for regions may be designated for remote acquisition, whereby alternate user actions in any non-target area of a region activate the primary and secondary targets respectively defined for that region. The central-area is divided into a varying number of shapes permitting users to activate application, system, or toolbar management activities.

A method and computer graphics system capable of super-sampling and performing real-time convolution are disclosed. In one embodiment, the computer graphics system may comprise a graphics processor, a sample buffer, and a sample-to-pixel calculation unit. The graphics processor may be configured to generate a plurality of samples. The sample buffer, which is coupled to the graphics processor, may be configured to store the samples. The sample-to-pixel calculation unit is programmable to select a variable number of stored samples from the sample buffer to filter into an output pixel. The sample-to-pixel calculation unit performs the filter process in real-time, and may use a number of different filter types in a single frame. The sample buffer may be super-sampled, and the samples may be positioned according to a regular grid, a perturbed regular grid, or a stochastic grid.

The present invention is directed to a method, system and program for exporting-importing the content of input cells from a source scalable template instance in a source multi-dimensional spreadsheet to a destination scalable template instance in a destination multi-dimensional spreadsheet; a multi-dimensional spreadsheet comprising a plurality of cells identified by a cell address along each dimension; a scalable template instance comprising a variable number of contiguous elements of same size ordered and aligned along a given spreadsheet dimension and structured according to information defined in an associated scalable template; an element being defined as a range of cells; a range of cells comprising one or a plurality of cells; said scalable template comprising an element profile; an element profile defining a cell content and a cell destination for each cell within each element; said cell destination specifying whether the cell is an input cell for receiving an entry or an output cell for producing a result. The method comprises the steps of: detecting a command for exporting-importing input cells from a source scalable template instance in a source spreadsheet to a destination scalable template instance in a destination spreadsheet; identifying the source scalable template associated with the source scalable template instance; identifying cells, if there are any, defined as input cells in the element profile of the source scalable template; identifying the destination scalable template associated with the destination scalable template instance; Identifying cells, if there are any, defined as input cells in the element profile of the destination scalable template; copying cell per cell, the content of each input cell of the source scalable 36 template instance in each input cell of the destination scalable template instance.

A harmonic suppression mixer for down converting an RF signal to a complex I and Q baseband signal that uses a plurality of switching mixers each with a gain stage to produce a sinusoidal weighted sum of the mixer outputs. Odd harmonics output by each switching mixer is suppressed in the composite signal. A low skew local oscillator (LO) clock generator creates multiple LO phases and drives the mixers. The mixer can be used in low noise direct conversion RF tuners. The mixer is configurable by programming gain stage coefficient values to achieve a variable number of effective mixers used in combination. At low tuning frequencies, all available mixers are programmed with unique coefficients and driven by different LO clock phases to achieve maximum harmonic suppression. At high tuning frequencies, some mixers are paralleled and duplicate coefficients are programmed or mixers are disabled to reduce the number of effective mixers.
