What Is Direct Memory Access Dma And

Using the i.MXRT L1 Cache - NXP

processor with a DMA controller. For i.MXRT, shareable means ... The background region has the same memory access attributes as the default memory map, but is accessible from privileged software only. ... then the core will still do a small amount of prediction (backwards direct branches will be predicted to be taken, forwards direct branches ...
