Exemple #1

Fichier : dma.cpp Projet : Godzil/quickdev16

void sCPU::dma_run() {
  dma_add_clocks(8);
  cycle_edge();

  for(unsigned i = 0; i < 8; i++) {

    dma_add_clocks(8);
    cycle_edge();

    unsigned index = 0;
    do {
      dma_transfer(channel[i].direction, dma_bbus(i, index++), dma_addr(i));
    } while(channel[i].dma_enabled && --channel[i].xfersize);

    channel[i].dma_enabled = false;
  }

  status.irq_lock = true;
