The DPU configuration registers are used to indicate instruction address, common address and mean value settings.

The reg_instr_addr register is used to indicate the instruction address of the DPU core.

The reg_base_addr register is used to indicate the address of input image and parameters for the DPU in external memory. The width of a DPU base address is 34 bits so it can support an address space up to 16 GB. All registers are 32-bit wide, so two registers are required to represent a 33-bit wide base address. The reg_base_addr0_l register represents the lower 32 bits of base_address0 in DPU core0, and reg_base_addr0_h represents the upper 2 bit of base_address0. There are eight groups of DPU base addresses for each DPU core, and therefore there are 40 groups of DPU base addresses for up to five DPU cores.

The details of configuration registers are shown in the following figure.
