    摘要： A multi-function timer used to perform multiple input timing measurements and generate multiple timed output events on the I/O pins of the apparatus. The multi-function timer comprises a plurality of slots and a compute engine. Each of the slots represents one of a plurality of timing processes. The compute engine includes a micro-sequencer and a processor. The micro-sequencer identifies a current slot and associated plurality of instructions representing a process, and is configured to serially sequence through each of the slots. The processor performs the functions of the instructions associated with each current slot. Further, each slot is configured to perform any one of the following timing processes: pulse width modulation, high speed input, high speed output, or delta time input. The multi-function timer is advantageous in that it provides application design flexibility by eliminating the need for dedicated logic for input and output timing functions.

    摘要翻译： 多功能定时器用于执行多个输入定时测量，并在设备的I / O引脚上产生多个定时输出事件。 多功能定时器包括多个时隙和计算引擎。 每个时隙表示多个定时处理中的一个。 计算引擎包括微定序器和处理器。 微定序器识别当前时隙和表示进程的相关联的多个指令，并且被配置为串行地顺序通过每个时隙。 处理器执行与每个当前时隙相关联的指令的功能。 此外，每个时隙被配置为执行以下定时处理中的任何一个：脉冲宽度调制，高速输入，高速输出或增量时间输入。 多功能定时器的优点在于它通过消除对输入和输出定时功能的专用逻辑的需要来提供应用设计的灵活性。

    摘要： A data queue control submodule supporting a host processor and at least one peripheral device. The submodule includes a memory unit with a first memory portion for storing queue commands associated with each peripheral device and a second memory portion for storing peripheral device data. A queue control unit is also included in the submodule for controlling the flow of data between the peripheral devices and the host processor in accordance with the queue control commands. A port interface connects the queue control unit and the peripheral devices in response to a trigger event. The submodule further includes an event controller in communication with the host processor and the port interface for generating event triggers in response to data demands of either the host processor or the other peripheral devices. The present invention is advantageous in that it simplifies the design of each port interface and provides improved flexibility in the queue structure of the overall control system.

    摘要： A method and system for generating a fuel pulse output signal to control fuel delivery from a fuel injector to a cylinder of an internal combustion engine. A plurality of holding registers asynchronously receive a plurality of fuel pulse data from a processor. The plurality of holding registers are memory-mapped and store the plurality of fuel pulse data until subsequent fuel pulse data is received from the processor. A plurality of match registers are coupled to the plurality of holding registers for comparing the fuel pulse data with a reference signal and generating a fuel pulse output signal based on the comparison between the fuel pulse data and the reference signal.
