| 20100109733 | Analog Comparators in a Control System - An apparatus is disclosed that includes first and second circuits coupled together via a bus, an input pin configured to receive an analog input signal, a digital-to-analog (DAC) convertor configured to convert a multibit reference signal into an analog reference signal, a comparator circuit coupled to the bus, an output of the DAC and to the input pin. The comparator circuit is configured to receive the analog reference signal from the DAC and the analog input signal, and configured to generate a first digital signal set to a first state if the analog reference signal is greater in magnitude than the analog input signal, or set to a second state if analog reference signal is lower in magnitude than the analog input signal. The comparator circuit is also configured to transmit the first digital signal to the first circuit via the bus. The first circuit in turn is configured to receive the first digital signal. In response to receiving the first digital signal, the first circuit is configured to generate a second digital signal set to the first or second state depending on whether the received first digital signal is set to the first or second state. The second circuit is configured to receive the second digital signal from the first circuit via the bus. | 05-06-2010 |
| 20100114376 | DIGITAL I/O SIGNAL SCHEDULER - An apparatus and method of scheduling signals. In one embodiment, the method includes a first circuit receiving a first plurality of reference values. The first circuit selects a reference value from the first plurality according to a first reference identifier (ID) that is stored in memory. The first circuit compares the selected reference value to a first match value. | 05-06-2010 |
| 20100191438 | Reference Distribution Bus - A system that includes a multiplexer having an output selectively coupled to a plurality of inputs, a bus coupled to the output of the multiplexer, and first and second circuits configured to generate first and second digital signals, respectively. The first digital signal is related to a rotational angle of a crankshaft at a first point in time, and the second digital signal is related to a value of parameter at the first point in time, wherein the parameter is one other than the rotational angle of the crankshaft. The first and second circuits are coupled directly or indirectly to first and second inputs of the multiplexer. | 07-29-2010 |
| 20100199014 | Microcontroller Peripheral Event Distribution Bus - A method and apparatus for distributing events. In one embodiment, the method includes a bus concurrently transmitting a first event-signal and a first event-identification (event-ID); wherein the first event-signal, when active, indicates that a first event has occurred, is occurring, or should occur. The first event-ID corresponds to the first event-signal. | 08-05-2010 |
| 20110090102 | xCP on 2 CSI - A microprocessor control unit (MCU) is mounted on a printed circuit board. The MCU includes first and second clocked serial interface (CSI) circuits. The first CSI circuit is configured to serially transmit a first xCP packet to a first encoder circuit, which in turn is configured to generate an encoded first xCP packet as a function of the first xCP packet and a first clock signal. A first low voltage differential signal (LVDS) circuit is coupled to the first encoder circuit and configured to serially receive the encoded first xCP packet therefrom. The first LVDS circuit is configured to generate a first differential signal as a function of the encoded first xCP packet. | 04-21-2011 |
