Abstract: Employed within an LED driver operating from the AC power line, the invention controls both input current and output power. With this regulation circuit, input current appears purely resistive, precisely tracking the input voltage waveshape. At the same time, it provides good line regulation and inherent phase dimmer compatibility, requiring no special circuitry to detect and handle a dimmer.

Abstract: A system and method transmit a data stream from a source to a destination over a communication channel. A transmitter includes devices for processing inputs to assemble data packets for the data stream, and a multiplexer for assembling a data frame to be transmitted over the communication channel, in which each data frame has at least one fixed slot. The multiplexer sets at least one freely allocatable time slot in each data frame. Retransmission control devices connected to the multiplexer retransmit a specific data packet which is not properly received by the destination, using one of the freely allocatable slots.

Abstract: Clock speed is controlled based upon the supply voltage to a digital device. When the supply voltage is below a reference voltage the clock speed will be slower than if the supply voltage is above the reference voltage. A phase-lock-loop (PLL) may be used to generate a higher frequency that is an integer multiple of a reference oscillator. The clock speed will be proportional to the frequency multiplication of the PLL when the faster clock speed is selected. A multiplexer is used to switch between different frequency sources, and a timer can be used to insure stable operation of the PLL. A status configuration register has status and control bits for indicating and controlling operation of the clock speed control. A universal serial bus (USB) device can operate at a slower clock with reduced operating voltage, and at a faster clock with increased operating voltage.

Abstract: A microcontroller apparatus is provided with an instruction set for manipulating the behavior of the microcontroller. The apparatus and system is provided that enables a linearized address space that makes modular emulation possible. Direct or indirect addressing is possible through register files or data memory. Special function registers, including the Program Counter (PC) and Working Register (W), are mapped in the data memory. An orthogonal (symmetrical) instruction set makes possible any operation on any register using any addressing mode. Consequently, two file registers to be used to some two operand instructions. This allows data to be moved directly between two registers without going through the W register. Thus, increasing performance and decreasing program memory usage.

Abstract: The present invention relates generally to functional pathway configurations at the interfaces between integrated circuits (ICs) and the circuit assemblies with which the ICs communicate. More particularly, the present invention relates generally to the functional pathway configuration at the interface between a semiconductor device (e.g., computer chips like microcontrollers, microprocessors, application specific integrated circuits (ASIC), programmable gate arrays (PGA) and other devices and/or combinations thereof) and the circuitry of a system including the chip. Even more particularly, the present invention relates to a 14-pin microcontroller functional pathway configuration for the interface between the microcontroller and a system in which the microcontroller is embedded to support infrared communications.

Abstract: An instruction set is provided that features multiple instructions and various address modes to deliver a mixture of flexible microcontroller-like instructions and specialized digital signal processing (“DSP”) execute instructions from a single instruction stream. A subset of instructions of the instruction set can be executed by a processor. Similarly, another subset of the instructions can be utilized by the digital signal processor. A software application can thus take advantage of digital signal processing capabilities in the same program, obviating the need for separate programs for separate processors.
