Some processors and DMA systems can figure out when the CPU will not be using memory for a bit and do transfers totally during that time. This is usually known as transparent mode.

Figure 5: dma-1 overexpression causes excessive branching. (a) By the L4 larval stage, PVD displayed complete candelabra structures. (b) Overexpression of dma-1 resulted in excessive PVD branching.

Figure 5. DMA shear measurement of PET in the range of –150 to +270 °C. Apart from the effects detected by TGA/DSC or TMA (for example, crystallization, glass transition, and melting), the DMA curve ...
