Flexible frame buffer architecture having adjustable sizes for direct memory access |
摘要 |
The present invention relates to a frame buffer used by a laser printer controller to send video signals to a laser printer engine. The frame buffer allows software to have sufficient control of the dimension of the buffer and to have sufficient time to process data by allowing software to change X and Y dimensions of the buffer. In addition, software controls the loading of the frame buffer start address.
