摘要： This application discloses a system for eliminating a busy line condition and completing a call over a virtual private line when the stations at each of the lines attempt to initiate a call simultaneously. The system is implemented in three phases. In a first phase, the busy line condition is detected by either the communication switching system which sets up the virtual private line or by two signal converters, each connected to a station set at each end of the line. In a second phase, the switching system or the converters send terminating supervisory signals towards each station to terminate the attempted initial calls while the stations are still off-hook. In a third phase, a predetermined signal converter or a selected switch in the communication switching system initiates a new call by emitting an originating supervisory signal while the stations are still off-hook.

摘要： A method and pixel interpolation system for non-linear interpolation of images having a plurality of input pixels and pixel positions. According to a preferred embodiment of the invention, a plurality of pairs of input pixels and a sequence of corresponding interpolation weights are received with a one-dimensional interpolator. A plurality of sequential weighted sums of the pairs of input pixels are provided at a plurality of the pixel positions in accordance with the interpolation weights. The sequence of interpolation weights is provided, where differences between pairs of successive interpolation weights of the sequence of interpolation weights differ. The sequence of interpolation weights is applied to the one-dimensional interpolator. The present invention may be utilized, for example, for performing the operations of shifting two-dimensional video images where the shifting operations are performed with non-uniform scaling in at least one of the dimensions, and may also be used when shifting an image with non-uniform scaling by a fractional pixel distance.

摘要： A central controller, such as an RF distribution shelf (RFDS) of a hybrid fiber/coax (HFC) access system, keeps track of the different channels assigned to different remote units, such as the network interface units (NIUs) of the HFC system. Information about the different channel assignments (e.g., for upstream channels) is broadcast to the remote units as part of the overhead bits in each of the downstream channels. Each remote unit monitors the broadcast messages and, over time, updates its own version of the data structure containing the channel assignments, as appropriate. In one embodiment, the central controller also transmits a second type of broadcast message indicating when changes in the channel assignments occur. In this embodiment, the second type of broadcast message is transmitted more frequently than the entire data structure containing the channel assignments, and the remote units only update their copies of the data structure when the second type of broadcast message indicates a change in the data structure.

摘要： A method and apparatus for translating a first address in a first address space, such as a processor address space, to a second address in a second address space, such as a system address space, are described. Data alignment signal determinations based on comparisons between destination and source addresses permit automatic replacement of virtual addresses with actual physical addresses to permit direct data transfer between devices. In one embodiment, the apparatus for translating comprises a processor; a page table having a mask register, a comparison value register, and a replacement value register; and a comparator coupled to the comparison value register and to the replacement value register. A programmable mask within the translation mask register is employed to partition a virtual address. A first subaddress comprises a subset of the bits of the first address and a second subaddress comprises remaining bits of the first address. The first subaddress is masked with a programmable mask value in the translation mask register and is compared by the comparator with successive comparison values in the comparison value register until a match comparison value is found. A programmable replacement value in the replacement value register corresponding to the match comparison value is concatenated with the second subaddress. The programmable replacement values, which correspond to programable map windows, permit the programmable mapping of virtual addresses into different predetermined regions of system virtual address space.

摘要： A display processor for a computer with graphics capability includes color map memories addressed by portions of pixel codes during display line trace intervals. The read-outs from these color map memories provide the primary color component signals from which the drive signals for the display monitor kinescope are derived. The pixel codes, from which color map memory addresses are derived, are supplied at video rate to the display processor from the serial output port of dual-ported video random access memory. The color map memories are loaded with new color map data during display retrace intervals. By supplying this new color map data from the serial port of the dual-ported video random-access memory, the color map memories can be rapidly updated.
