Abstract: The current application is directed to control of lighting systems and utilization of ambient light levels for such control. One implementation comprises one or more lighting fixtures installed in a structure, at least one ambient light information source configured to provide brightness information of ambient light of the structure, and a controller configured to maintain a brightness level of an interior portion of the structure substantially the same as a brightness level of an exterior portion of the structure by controlling outputs of the lighting fixtures in response to the brightness information of the ambient light. The interior portion of the structure may include an entrance portion of the structure. The controller may be further configured to gradually reduce brightness levels of the outputs of the lighting fixtures from the entrance portion towards a center of the structure.

Abstract: A two port high speed integrated circuit memory device that includes a bus transceiver, a memory array and a decoder. The present invention provides a processor high speed access to the internal memory array via very low capacitive load address and data buses. The present invention also buffers a secondary bus to provide access to slower-speed local devices. The bus transceiver transfers address, data and control signals between the primary and secondary port and also couples signals to the internal memory array. The bus transceiver includes an input data bus, an output data bus, and an address and control bus. Each of these separate buses include a buffer at the primary and secondary port to minimize capacitive loading. The decoder in the two port memory device decodes memory chip select signals and control signals that define the operational mode of the device.

Abstract: A Cache Memory Controller which operates in conjunction with a TAG Random Access Memory (TAG RAM) coupled to the lower order bits on a host address bus is provided. The Cache Memory Controller selects the data to be written to TAG RAM from two or more sources. One of these sources provides snoop address signals and another provides invalidating signals. During a read operation, the lower order bits of the address on the address bus address the TAG RAM while the n higher order bits are passed to a shifter and to a compare circuit. In response to the lower order bits of the address provided, the TAG RAM generates an n-bit TAG data output signal. If this data output compares exactly with the n higher order bits on the host address bus, the compare circuit will indicate a hit. If the compare circuit does not indicate a hit, the n higher order address bits are written into the TAG RAM. Data from main memory is then loaded into the cache memory.

Abstract: A method and apparatus are provided for controlling clocks for a processor and L2 cache. The clock signal to an L2 cache may be shut down in order to conserve power. Due to the nature of CMOS circuitry typically comprising the SRAM in an L2 cache, shutting down the clock signal to the L2 cache may significantly reduce the amount of power consumed by the L2 cache. A clock control circuitry may be provided to generate and control clock signals to a processor (e.g., Pentium.RTM. processor) and an L2 cache. Controllable clock skew adjustment may be provided to adjust relative timing between clock signals. Skew adjustment for the L2 cache clock may be provided with an AND gate for interrupting the clock signal. The AND gate may be controlled by one of a number of signals indicating status of the L2 cache. Address strobe, L2 idle, or pipelining conditions may determine whether the clock signal to the L2 cache may be interrupted.
