US Classification:

710112, 710 5, 710 19, 701 48

Abstract:

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.

International Classification:

G06F013/00

US Classification:

710316, 710317, 710 38, 370391

Abstract:

A controller has an I/O crossover switching network , an optional I/O network expansion , a plurality of serial I/O shifters , a clock generator and I/O control logic. The I/O crossover-switching network is also referred to as an I/O multiplexer. Serial data may be transferred between a serial I/O shifter and an external device by way of a dedicated serial data pin (SDATA) or an optional alternate pathway which uses one of a plurality of parallel pins. The optional alternate pathway can be used when pins are unavailable or to reduce the number of pins on the device. The controller is shown to communicate with an external device also having parallel pins. While a single device is shown, the external device can be any number of a plurality of devices having serial and parallel signal pathways that is controlled by the microprocessor of the present invention.

International Classification:

F02P 707
F02P 515

US Classification:

123414

Abstract:

A method and system for generating a position dependent output control signal. The position of a rotating machine, such as an internal combustion engine, is sensed and a corresponding position signal is generated. The position signal is processed to obtain the position dependent output control signal including a first control signal and a second control signal. The first control signal represents a sector of the rotating machine, and the second control signal represents the absolute position within the sector.

US Classification:

701104

Abstract:

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.

International Classification:

G06F 1300

US Classification:

395825

Abstract:

Serial communication circuitry (10) having multiple queues (11-14) for use in a data processing system (95). Each queue (11-14) has multiple entries (52). Serial transfers from the multiple queues (11-14) are carried out under the control of global parameters (e. g. 205, 209), per-queue parameters (e. g. 211-212, 214-217), and per-entry parameters (e. g. 350-361). Each queue can be programmed to have a different set of per-queue parameters, and each entry within a queue can be programmed to have a different set of per-entry parameters. In addition, serial communication circuitry (10) can perform serial data transfers in response to the assertion of a trigger signal (30) from a source such as a timer (63) or a central processing unit (61). As a result, data transfers can be more precisely related to a particular timing signal or set of timing signals.
