  • Patent number: 5875348
    Abstract: Disclosed is a computer system that includes a CPU that can be operated both in a normal mode and in a power saving mode. The system further includes at least one peripheral device and a bus for allowing communication between the CPU and the peripheral device. A bus cycle detector monitors a bus cycle on the bus and a condition determiner determines the operation mode for the CPU in a specific bus cycle that is detected by the bus cycle detector. A signal generator is used to provide to the CPU, a control signal for changing the CPU's operation mode in accordance with a determination result obtained by the condition determiner. The disclosed system can reduce the operating frequency of a CPU or halt the operation of the CPU in accordance with an appropriate timing even when asynchronous communication is performed with peripheral devices.

  • Patent number: 5155478
    Abstract: A system for converting selected M gray levels in a K-gray scale to M identifiable levels in an N-gray scale, where K>N.gtoreq.M. A first table is created in which the respective M gray levels of the K-gray scale are mapped to different levels in the N-gray scale, which levels have the relative order and magnitude of their brightnesses in the K-gray scale, and using this first table, a second table is created in which the M gray levels in the N-gray scale are mapped to their corresponding M gray levels in the K-gray scale on a one-to-one basis according to the first table. Using the second table, any M gray levels in a K-gray scale can easily be converted to ones in an N-gray scale on a one-to-one basis with the relative order and magnitude of the brightnesses of those M gray levels being maintained.
