摘要： An apparatus, a method, and a computer program are provided for the generation of constant incremental increases while changing core clock frequencies. In computer systems, oftentimes frequency changes are useful. Maintaining the clocking ability of the computer system, though, can be a difficult task. To maintain the time keeping ability, time base logic is utilized with the free-running clock, which can be frequency limited. However, a plurality of communication channels in conjunction with an adder system is employed to effectively adjust for an ever increasing frequency to allow for a effective timekeeping regardless of the core frequency.

摘要： A simple, approximate power optimization in connection with automatic large scale circuit design using a cell library is provided. The cell library of the present invention provides active region information for each cell, and preferably also provides conventional parameters such as cell physical area and cell performance information. Typically, several cells having differing parameters correspond to each cell function provided by the library. A cost function is defined which depends on active region information, and can also depend on physical area and performance. A cell design including cells selected from the library is optimized by substitution of functionally equivalent cells from the library to minimize the cost function. Minimization of active region area provides a simple way to approximately minimize power consumption. Optionally, a second optimization can be performed with a higher fidelity power model using the approximately power-minimized design as a starting point.

摘要： A light emitting diode incorporating an active emitting layer (14) overlying a transparent substrate (10) is provided with a reflective diffraction grating (30) on the bottom surface of the substrate. Emitted light passing downwardly through the substrate is diffracted outwardly toward edges (21) of the substrate and passes out of the die through the edges. This effect enhances the external quantum efficiency of the diode.
