ABSTRACT:
A method is provided for programming a DMA controller in a system on a chip. According to the method, a memory management unit translates a programming virtual address into a programming physical address according to a translation table. A first sub-block without discontinuity beginning at the programming physical address and ending at an end address equal to the physical address immediately preceding a first discontinuity is formed, with the first discontinuity being determined by a discontinuity module according to information supplied by a memory management unit. Some of the programming elements intended for the DMA controller are defined according to the first identified sub-block. Also provided is a system on a chip.
