摘要： To provide reduced power consumption of a co-processor, a low power dedicated memory is provided. During a low power state, a processing component of the co-processor is instructed to use the low power dedicated memory and a first memory device, normally used by the processing component, is thereafter operated in a reduced power mode for the duration of the low power state. Preferably, the low power dedicated memory has a storage capacity that is significantly less than the storage capacity of the first memory. When an operating state other than the low power state is detected, normal power consumption by the first memory is resumed and the co-processor is directed to use the first memory once again. In this manner, the present invention allows co-processors, and preferably graphics co-processors, to operate in a beneficial low power mode thereby reducing power consumption.

摘要： An integrated circuit includes a core-logic providing a core-logic output, a latch in communication with the core-logic to store a state of the core-logic output, and an isolation circuit for selectively interconnecting the core-logic output to an input of the latch. The circuit also includes and a power consumption controller in communication with the core-logic, the latch and the isolation circuit, for controlling the latch to store a state of the core-logic output, and output a corresponding signal. The controller is further operable to signal the isolation circuit to isolate the core-logic output from the latch by providing an output corresponding to predetermined value and transition the core-logic from a high power state and a low power state. This prevents transient signals from propagating to interconnected circuit blocks and external devices.

摘要： A method of enhancing photographic images of low optical density is disclosed which includes use of a luminescent system, the components of which system include, at least, photoluminescent material and a source of photons for exciting the same to luminescence. A photoluminescent replica of the low optical density photographic image is produced which replica is exposed to photons required for luminescence of the photoluminescent image replica which luminescence is recorded, or photographed, for an amount of time necessary to achieve enhancement of the photographic film image. The image enhancement method may be used for the enhancement of photographic images produced by photographic processes including, for example, those which involve the use of different radiant energy sensitive material such as silver halide as used in `conventional` photography, photoconductive material as used in electrophotography, organic compounds as used in diazo photographic processes, and the like.

摘要： An apparatus and method of treating multiple wafers to reduce the density of impurities as well as to improve the uniformity of substrate electrical characteristics without any thermal stress. The wafers are chemically treated, and heat treated in a sealed reaction tube under arsenic overpressure with a controlled thermal profile to heat the wafers. The thermal profile controls temperature of different zones inside of a furnace containing the sealed reaction tube. Impurities of the wafers are dissolved, and are out-diffused from the inner portions to the outer portions of the wafers.

摘要： A technique increases the number of colors output by an active color display by providing an increased number of grey levels for each pixel component. An M×N matrix pattern of pixel components is generated having a ratio of pixel components at a particular color level to pixel components at a different color level to achieve a particular grey level, where M and N are greater or equal to two. The M×N matrix pattern is repeated for X frames, and at least one pixel component is at the particular color level in each frame. At the end of the Nth frame, the matrix pattern from frame zero is repeated.

摘要： A technique to increase the number of colors output by a passive color LCD display provides an increased number of grey levels for each pixel component. An M×N matrix pattern of pixel components is generated having a ratio of pixel components that are ON to the total number of pixel components to achieve a particular grey level on the passive color LCD screen, where M and N are greater or equal to two. The M×N matrix pattern is repeated for X frames, and at least one pixel component is ON in each frame. At the end of the Xth frame, the first matrix pattern for frame zero is repeated.
