Abstract:
1. A graphics system comprising: a display engine for receiving and processing graphics data to generate a graphics image; a graphics filter for converting a format of the graphics image from a first format to a second format when the graphics system operates in a standard definition (SD) mode, but not in a high definition (HD) mode; and a plurality of line buffers implemented in a single-port RAM, each said line buffer for temporarily storing a line of the graphics image, the line buffers being accessed in an interleaved manner, such that a read operation is performed between a first write operation and a second write operation, wherein the write operations are performed on one said line buffer being pointed to by a pointer when multiple said line buffers are used, and wherein the first and second write operations are performed using two sequential memory locations of the line buffers.
