Method and system for sharing a hardware resource

A method for sharing a hardware resource in a system for an engine operation, comprising the steps of:

• monitoring changes in state in the cylinder of the engine using a pickup device;
• accessing a memory containing control parameters required by the hardware resource in response to a state signal from the pickup device;
• applying one of a start and a duration signal to the hardware resource, the start and duration signals being related to the accessed control parameters;
• and
• connecting the hardware resource to a selected one of several output devices, each of said output devices being associated with a particular cylinder of the engine and being selected in relation to the state signal.

A method for sharing hardware resources in a system for an engine operation, comprising the steps of:

• monitoring changes in state in the engine using a pickup device;
• accessing a memory containing control parameters required by a first hardware resource in response to a state signal from the pickup device;
• applying a start signal to said first hardware resource, the start signal being related to the accessed control parameters;
• connecting said first hardware resource to a selected one of several output devices, each of said output devices being selected in relation to the state signal;
• accessing a memory containing control parameters required by a second hardware resource in response to the state signal from the pickup device;
• applying a duration signal to said second hardware resource, the duration signal being related to the accessed control parameters;
• and
• connecting said second hardware resource to one of said several output devices, the one of said several output devices being selected in relation to the state signal.

A system for sharing a hardware resource, comprising:

• a memory for storing control parameters;
• a microprocessor in communication with the memory for updating the control parameters;
• a pickup device for generating a state signal corresponding to the state of the system;
• selection means responsive to the state signal for selecting one of the control parameters from the memory;
• means for applying a control signal related to the selected control parameter to the shared hardware resource;
• and
• a switch in communication with the shared hardware resource and selectively in communication with one of a plurality of output devices, the one of the plurality of output devices being selected in relation to the state signal.

A system for sharing a hardware resource, comprising:

• a memory having control parameters stored therein;
• a microprocessor in communication with said memory;
• a pickup device connected to the system, said pickup device generating a state signal corresponding to a state of the system;
• a data selector responsive to the state signal, said data selector connecting one of the control parameters from the memory to the shared hardware resource;
• and
• a switch responsive to the state signal to connect one of a plurality of output devices to the shared hardware resource.

A system having N states for sharing at least two hardware resources, comprising:

• a memory having control parameters stored therein;
• a microprocessor in communication with said memory;
• a pickup device connected to the system, said pickup device generating state signals, each of said state signals corresponding to different one of the N system states;
• a first data selector responsive to one of said state signals, said data selector connecting one of the control parameters from said memory to a first shared hardware resource;
• a first switch responsive to one of said state signals to connect one of a plurality of output devices to the first shared hardware resource;
• a second data selector responsive to another of said state signals, said data selector connecting another of the control parameters from said memory to a second shared hardware resource;
• and
• a second switch responsive to another of said state signals to connect another of the plurality of output devices to the second shared hardware resource.
