Abstract: A loop buffer is provided with a main store 26 and an auxiliary store 28. The main store 26 stores micro-operation instructions. The auxiliary store 28 has fewer entries than the main store 26 and stores target addresses for predicted taken branch instructions stored within the main store 26. Read control circuitry serves to control reading from the main store and from an auxiliary store such that target addresses are read from the auxiliary store in association with the predicted taken branch instructions read from the main store.

Abstract: A method and a data processing apparatus operable to process instructions from a plurality of instruction sets, the plurality of instruction sets each sharing a sub-set of common instructions and each having a remaining set of instructions is disclosed. The data processing apparatus comprises: a plurality of decode units, each decode unit being operable to only decode the remaining set of instructions from a corresponding one of the plurality of instruction sets; and a common decode unit operable to decode a number of the sub-set of common instructions from each of the plurality of instruction sets. This enables the common instructions from each instruction set to be decoded by the common decode unit. Hence, the logic which would otherwise be duplicated in each of the individual decode units for each instruction set can be removed from those decode units and provided just once in the common decode unit.

Abstract: An out-of-order renaming processor is provided with a register file within which aliasing between registers of different sizes may occur. In this way a program instruction having a source register of a double precision size may alias with two single precision registers being used as destinations of one or more preceding program instructions. In order to track this data dependency the double precision register may be remapped into a micro-operation specifying two single precision registers as its source register. In this way, scheduling circuitry may use its existing hazard detection and management mechanisms to handle potential data hazards and dependencies. Not all program instructions having such data hazards between registers of different sizes are handled by this source register remapping. For these other program instructions a slower mechanism for dealing with the data dependency hazard is provided.

Abstract: A data processing system including multiple execution pipelines each having multiple execution stages E1, E2, E3 may have instructions issued together in parallel despite a data dependency therebetween if it is detected that the result operand value for the older instruction will be generated in an execution stage prior to an execution stage which requires that result operand value as an input operand value to the younger instruction and accordingly cross-forwarding of the operand value is possible between the execution pipelines to resolve the data dependency.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes an actuator and a controller operable to cause the light intensity level of the at least one lamp to fade at a first fade rate that is based on the initial light intensity level of the at least one lamp upon a determination that the actuator has been actuated, to fade to off at a second fade rate upon a determination that the actuator has been actuated for only a single transitory duration, to fade from the initial intensity level to a preset desired intensity level at a third fade rate upon a determination that the actuator has been actuated for two successive transitory durations, and to fade to off in a predefined fade rate sequence upon a determination that the actuator has been actuated for more than a transitory duration. The first fade rate is based on a predefined fade-off time.

Abstract: Within a multiple instruction pipeline data processing system which supports predication instructions, program instructions are initially decoded upon the assumption that they are predicated. A predication signal is generated within the instruction decoder stages when a predication instruction is detected. The presence or absence of this predication signal can then be used to correct any decoding which has been performed upon the basis of an assumption that the program instructions are predicated. The predication instruction can predicate a variable number of following instructions. The predication instruction can issue in parallel with an instruction which it predicates and yet the proper identification of the predication instruction need not be confirmed until at least some decoding has been performed upon the other program instruction.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes an actuator and a controller, such as a microcontroller, for example. The controller is operable to cause the light intensity level of the lamp to fade at a first fade rate when the actuator is actuated. If the controller determines that the actuator has been actuated for at least a predefined hold time, the controller causes the light intensity level of the lamp to fade at a second fade rate for a predefined long fade time. After the long fade time elapses, the controller causes the light intensity level of the lamp to fade to off at a third fade. The first fade rate is based on a predefined fade-off time that represents a time allotted for fading the light intensity level of the lamp from its initial light intensity level to off.

Abstract: An independent radio frequency programming device automates a setup process for a lighting system with lighting control devices and master controls. The programming device intercepts communications between the lighting control devices and the master control during an initial setup phase. A start function permits the programming device to provide automated setup information to the master controls. Once the automated setup process completes, the lighting system is fully programmed with behavior functions for all lighting control devices.

Abstract: A lighting control device for controlling the light intensity level of at least one lamp is disclosed. The lighting control device includes a microcontroller and a user-actuatable switch controller that is operatively coupled to the microcontroller. The microcontroller causes the light intensity level of the lamp to fade at a first fade rate when the switch controller is actuated. If the microcontroller determines that the switch controller has been actuated for at least a predefined actuator hold time, the microcontroller causes the light intensity level of the lamp to fade at a second fade rate for a predefined long fade time. After the long fade time elapses, the microcontroller causes the light intensity level of the lamp to fade to off at a third fade. The first fade rate is based on a predefined fade-off time that represents a time allotted for fading the light intensity level of the lamp from its initial light intensity level to off.

Abstract: A method for operatively interconnecting a first and second lighting control subnet is disclosed. In the method, a link claim is transmitted to the first and second lighting control subnets from a bridge. The link claim directs the first and second lighting control subnets to wait for a lighting control command, which is transmitted to the lighting control command to the first lighting control subnet. A random wait time is assigned to the first lighting control subnet and a maximum random wait time is assigned to the second lighting control subnet. Finally, an acknowledgement is received from the first lighting control subnet.
