Systems and methods for dynamically controlling a bus

A method for dynamically accessing a bus having a plurality of devices operationally connectable thereto, each of said devices having a priority level associated therewith, said method comprising the step of:

• controlling the duration of access to the bus by a first of said devices based on the combination of a latency timer and the priority level associated with the first device, and a priority level associated with a pending request by a second of said devices to control the bus.

A system for dynamically controlling a bus, said system comprising:

• a plurality of devices, each of said devices having a priority level and a latency timer associated therewith;
• and
• a bus controller, operationally connectable to each of said devices, for controlling the duration of control of a bus by a first of said devices based on the combination of the latency timer and the priority level associated with the first device, and a priority level associated with a pending request by a second of said devices to control the bus.

A system for dynamically controlling access to a bus having a plurality of devices operationally connectable thereto, each of said devices having a priority level associated therewith, said system comprising:

• means for receiving a request to control the bus and a priority level associated with the request from a second of said devices;
• and
• feedback means for transmitting the priority level associated with the request received from the second device to a first of said devices having control of access to the bus in response to the receipt of the request from the second device.

A system for dynamically accessing a bus, said system comprising:

• a plurality of devices, each of said devices being operationally connectable to the bus and having a priority level associated therewith;
• and
• duration means for controlling the duration of access to the bus by a first of said devices based on the combination of a latency timer and the priority level associated with the first device, and a priority level associated with a pending request by a second of said devices to control the bus.

A computer program product for dynamically controlling a bus having a plurality of devices operationally connectable thereto, each of said devices having a priority level associated therewith, said computer program product comprising:

• a computer readable storage medium having computer readable code means embodied in said medium, said computer readable code means comprising:
• computer instruction means for controlling the duration of control of the bus by a first of said devices based on the combination of a latency timer and the priority level associated with the first device, and a priority level associated with a pending request by a second of said devices to control the bus.
