The following table lists the DPU I/O signals and their function descriptions.

Table 1. DPU Signals
Signal Name Interface Type Width I/O Description
s_axi_control Memory mapped AXI slave interface 32 I/O 32-bit memory mapped AXI interface for registers.
ap_clk Clock 1 I Kernel clock. The frequency of the clock should match the clock of the DPU core. The supported frequencies are 300 MHz, 275 MHz, and 250 MHz.
ap_clk_2 Clock 1 I Reference clock for the MMCM in the DPU. It is set to 100 MHz.
ap_rst_n Reset 1 I Active-Low reset for DPU general logic.
ap_rst_n_2 Reset 1 I Unused in the core.
