Abstract: A method for constructing the Minkowski sum and derivative morphological combinations of arbitrary polyhedra uses operations supported in current CAD/CAM systems. The method has application to three-dimensional modeling of very large scale integrated (VLSI) circuits, their design and simulation of fabrication, and to automated mechanical assembly. The method also has application to n-dimensional modeling in robotics as well as other applications of CAD/CAM systems. In one aspect, an exact Minkowski sum of two polyhedra is obtained by a generalization of sweeping a face along an edge. More generally, according to a second aspect, the Minkowski sum of two polyhedra is computed as the union of linear translational sweeps enabled by the first aspect. The method implements techniques and formulas which greatly reduces the overall cost of the computation of Minkowski sums and, in particular, avoids computations involving non-transversal polyhedra. In a third aspect, the method reduces the difficulty of computing the Minkowski sum of a convex polyhedron and a general polyhedron by using simpler surrogate sets for the convex polyhedron.

Abstract: A communication link quality estimator (LQE) (80) is disclosed, for a link employing a M-ary modulation scheme. The LQE (80) is employed at the receiver (70), which includes a M-ary decoder (76) responsive to received M-ary symbol channel bits for decoding the M-ary symbol into a set of M-ary decoded bits. The LQE (80) includes a time delay circuit (84) for providing a version of the received channel bit M-ary symbol delayed in time by one symbol period. The LQE (80) converts the set of M-ary decoded bits into an auxiliary M-ary channel bit symbol representation in accordance with the M-ary modulation scheme, and compares on a bit-by-bit basis (86) the delayed version of the received channel bit symbol and the auxiliary symbol representation. Detected errors are counted and averaged over a fixed block length to provide a bit error rate estimator.

Abstract: A display system has signal lines (21) and scanning lines (20) arranged in a matrix with the signal lines (21) extending generally perpendicular to the scanning lines (20). At each intersection of the signal (21) and scanning lines (20) there is a display unit, each such unit having a display element (24) such as a liquid crystal display element, switching means (23) between the display element (24) and the signal line (21), and current limiting means (22) between the switching element (23) and the scanning line (20). By applying suitable signals to the signal (21) and scanning (22) lines, from suitable signal and scanning controllers (31,32), each display unit may be addressed. In order to prevent defects due to a short circuit across the switching element (23) between the current limiting means (22) and the signal line, signals are applied to the signal lines at times other than when signals are applied to the scanning lines (21), so as to apply a suitable voltage to any defective display unit so as to cause the display element (24) to be controlled so that it is in the desired state. Thus, if the display elements (24) are liquid crystals, they may be controlled so as to be dark if they are faulty.

Abstract: A system and method for high-efficiency checkerboard memory self-test is disclosed. A random pattern generator configuration includes a linear feedback shift register and a multiple input signature register. The random pattern generator is used to step through the memory addresses in generating the checkerboard pattern. The two least significant address lines connecting the random pattern generator and the memory array are connected together via an exclusive OR gate. Because these address lines indicate whether the next memory address to be generated is of the same or different type of state compared to the current memory address. The output of the exclusive OR gate can thus be connected to the data input shift register of the memory array to permit conditional shifting of the checkerboard data pattern into the memory array. One logic state is input to the current memory address when the output of the exclusive OR gate is a logical one and the other logical state is input to the current memory address when the output of the exclusive OR gate is a logical zero.

Abstract: A system and method for instrumenting the execution of instructions in an out-of-sequence execution machine. Instructions tagged with a preselected instruction identification number (IID) are identified. When an instruction having the preselected IID is encountered, information associated with that instruction is saved as the out-of-sequence execution proceeds. If the instruction completes, the information is stored as a single instrumentation entry in a memory array. If the instruction does not complete, the information is disposed of. The process id repeated for each instruction having the preselected IID until the memory array is full. The storage of instruction information in the memory can be further conditioned on the occurrence of a cache miss or other system conditions.

Abstract: An image rotation method and an image rotation processing apparatus in an image processing apparatus are disclosed. The image rotation method obtains the coordinates (x',y') of a second memory (6) where the rotated image will be recorded, by sequentially scanning a first memory (5) where the M× N original image is recorded and adding the increments of x and y corresponding to a rotation angle ϑ repeatedly, and transmits the image element data of the coordinates (x,y) of the first memory (5) to the coordinates (x',y') of the second memory (6) with one-to-one correspondence, thereby obtaining the rotated image through the rotation angle ϑ from the original image. Thus, the present invention can obtain the rotated image using only addition operations and without any multiplication operations, so that high-speed operation is possible and an image can be rotated through a specified angle ϑ through software in common computer graphic systems having no floating point multiplier.

Abstract: An integrated circuit package comprises a thermally conductive plate for receiving an integrated circuit and an open rectangular structure of conductor and insulator for surrounding the sides of the circuit and presenting one or more linear arrays of conductive connectors extending laterally through the rectangular structure. Preferably the rectangular structure also includes transverse contacts. Advantageously the plate includes extensions beyond the rectangular structure for acting as cooling fins on opposing sides of the rectangular structure. The linear arrays and cooling fins are preferably on different pairs of parallel sides. 
     The integrated circuit package permits the aggregation of packages into assemblies and into clusters of assemblies rich in interconnections. Vertically stacked packages form a rectangular parallelepiped having a plurality of parallel planar cooling fins projecting from two opposing surfaces and another pair of planar surfaces providing rectangular arrays of contacts to the enclosed integrated circuits. In addition, transverse contacts permit electrical interconnection of the stacked packages. 
     Linear clusters can be aggregated as a linear array of such assemblies with their contact surfaces interconnected either directly by an anisotropically conducting plane or indirectly by an intervening transformation plane. In a preferred linear cluster, successive assemblies are rotated by 90° with respect to the axis of the array. In such clusters each package in the rotated assembly contacts each package in the neighboring assemblies. In low power equipment, elimination of the cooling fins permits even higher levels of interconnection such as rectangular clusters of assemblies.
