2.4 Data Memory Controller
Figure 2–3. TMS320C6x Block Diagram
As shown inFigure 2–3, the data memory controller connects:
The CPU and direct memory access (DMA) controller to internal data
memory and performs the necessary arbitration.
CPU to the external memory interface (EMIF).
The CPU to the on chip peripherals through the peripheral bus controller.
The peripheral bus controller performs arbitration between the CPU and DMA
for the on-chip peripherals.
