Abstract
The present teaching relates to method, system, medium, and implementations for data transfer in LED display. A signal signaling a timing for a next data transfer is received. In response to the signal, a next data transfer instruction is obtained that instructs reading a bit-based image block of an image from a memory. The bit-based image block is transferred, according to the next data transfer instruction, from the memory via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer. Then, the write buffer pointer is toggled to point to another of the pair of alternate buffers and the process repeats. The bit-based image blocks alternately stored in the buffers are later retrieved and displayed on the LED display.
