Abstract: A distributed I/O device monitoring logic for power management control. The distributed I/O device monitoring logic reduces the gate count of convention device monitoring logic since the decode logic does not exist at two locations in the system. The distributed I/O device monitoring logic also has the benefits of self configuring monitor circuits, improved functionality, and decreased system power management overhead. The distributed I/O device monitoring logic comprises peripheral control for monitoring an I/O address range of at least one I/O device and for detecting access to the I/O device; system controller means coupled to the peripheral control for providing a ready (RDY #) signal and a system management interrupt (SMI #) signal; and central processing unit (CPU) coupled to the peripheral control and the system controller means for receiving the RDY # signal and the SMI # signal from the system controller and for sending information to both the system controller and the peripheral control.

Abstract: A method for selectively controlling the operation of a computer system so that the computer system is selectively caused to execute instructions of a first predetermined bit length or instructions of a second predetermined bit length. The method comprises the preliminary steps of storing instruction data in a set of EVEN instruction storage locations; storing instruction data in a set of ODD instruction locations; establishing an EVEN execution pointer; and establishing an ODD execution pointer. At a first given time, either the EVEN execution pointer is incremented by a predetermined COUNT or the ODD execution pointer is incremented by the predetermined COUNT; but both pointers are not simultaneously incremented by the COUNT. The method causes an instruction to be executed, which instruction was stored entirely in either an EVEN instruction location or entirely in an ODD instruction location.

Abstract: A programmable output pad is disclosed that reduces ground bounce noise and power supply noise under different power supply values and under different load conditions. The programmable output pad comprises a pre-driver, a driver, and a controllable delay. The pre-driver transfers a signal from the input of the output pad to the driver which, in turn, transfers the signal from the pre-driver to an output of the output pad. The controllable delay provides one or more resistors, transistors, transmission gates, or equivalents thereof at the input of the driver which are controlled in order to provide a plurality of different time delays. By selecting these different time delays, the activation of the driver is delayed by different amounts of time. For a given power supply value and load condition, selection of the proper delay effectively reduces both the ground bounce noise on the ground supply of the programmable output pad and the noise on the power supply of the programmable output pad.

Abstract: An improved platformed vehicle having a steerable front wheel is disclosed. The vehicle includes a bifurcated platform with the tail of the platform being divided into first and second branches. Rear wheels are mounted, in pairs, on the underside of each of the branches of the platform. A pair of steerable front wheels are mounted below the platform near the front of the platform. The sprocket wheels are also attached to the underside of the front of the platform. The first sprocket wheel is coupled to the steerable front wheel, while the second sprocket wheel, mounted just behind the first sprocket wheel, is couple to a steering mechanism which passes through the platform. A chain drive couples the two sprocket wheels and thus couples the steering mechanism to the front wheels. The second sprocket wheel has a larger diameter than does the first sprocket wheels so that small turns of the steering mechanism are translated into relatively large changes in the front wheel direction.
