Figure 4-6 shows the AP framework.

Figure 4-6 AP framework

The K3V200 system uses the Hi3620 chip as its core to provide the following logical
interfaces:
NAND/eMMC Interface
The Hi3620 provides 16-bit NAND interfaces. Of the 16-bit width, the eight high-order bits
are multiplexed with the eMMC interface. Therefore, it is recommended that the eight
high-order bits be connected to the eMMC component and the eight low-order bits be
connected to a component such as the MLC NAND or Clear NAND.
Camera Interface and LCD Interface
The Hi3620 provides three MIPI interfaces: CSI0, DSI0, and CSI_DSI1. Each interface can
contain four data lanes. The Hi3620 also provides one parallel camera interface which is
known as the DVP interface.
