The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An image display system, comprising:
a first memory;
a memory controller configured to generate an interrupt signal in response to a command to write first image data into a first range of addresses within the first memory that at least partially overlaps with a reference range of addresses, said memory controller comprising an address comparison circuit configured to determine whether the first range of addresses at least partially overlaps with the reference range of addresses; and
a driver configured read the first image data from the first memory in response to the interrupt signal.
2. The system of claim 1, wherein said memory controller further comprises a register configured to store at least a starting address associated with the reference range of addresses.
3. The system of claim 1, further comprising a display module configured to receive the first image data from said driver.
4. The system of claim 3, wherein said display module comprises a frame buffer configured to store the first image data received from said driver.
5. The system of claim 1, wherein said memory controller is further configured to write second image data into a second range of addresses within the first memory without generation of the interrupt signal when the second range of addresses is outside the reference range of addresses, in response to a command to write second image data into the second range of addresses within the first memory.
6. The system of claim 5, further comprising an arbitration circuit configured to provide said memory controller with a first packet of data comprising the write command, the first image data and at least a starting address associated with the first range of addresses.
7. The system of claim 1, further comprising an arbitration circuit configured to provide said memory controller with a first packet of data comprising the write command, the first image data and at least a starting address associated with the first range of addresses.
8. A method of operating an image display system, comprising:
comparing a first range of memory addresses associated with a first packet of image data against a reference range of addresses to detect at least a partial overlap therebetween concurrently with writing first image data contained within the first packet into a first memory device;
generating an interrupt signal in response to detecting the at least a partial overlap between the first range of memory addresses and the reference range of addresses; and
transferring the first image data from the first memory device into a frame buffer within a display module, in response to the interrupt signal.
9. The method of claim 8, wherein said transferring comprises:
reading the first image data from the first memory device into a device driver configured to receive the interrupt signal; and
writing the first image data from the device driver into the frame buffer.
10. The method of claim 9, wherein said comparing comprises evaluating a header of the first packet to detect presence of a write command therein.
11. A method of processing image data, the method comprising:
determining a type of a packet provided from at least one application;
selectively determining whether addresses included in the packet are at least partially overlapped with a reference address range; and
selectively processing image date included in the packet based on determining whether the addresses included in the packet are at least partially overlapped with the reference address ranges.
12. The method of claim 11, wherein whether the addresses included in the packet are at least partially overlapped with the reference address range is determined when the type of the packet indicates a write packet.
13. The method of claim 12, wherein when addresses corresponding to the image data are at least partially overlapped with the reference address range, the method further comprising:
processing the image data to provide the processed image data to a frame buffer.
14. The method of claim 12, wherein when addresses corresponding to the image data are at least partially overlapped with the reference address ranges, the image data is processed in response to an interrupt signal.
15. The method of claim 11, wherein the reference address range includes a plurality of sub reference address ranges.
16. The method of claim 15, wherein the image data is processed when the addresses corresponding to the image data is at least partially overlapped with at least one of the plurality of sub reference address ranges.
