The primary function of the data controller module is to schedule the data flow
in the DPUCZDX8G IP. The data controller module
works with m_axi_dpu_aclk. The data transfer between the
DPUCZDX8G and external memory happens in
the data controller clock domain, so m_axi_dpu_aclk is
also the AXI clock for the AXI_MM master interface in the DPUCZDX8G IP. m_axi_dpu_aclk should
be connected to the AXI_MM master clock.
