A high state on reg_dpu0_start signals the start of a DPUCZDX8G task for DPUCZDX8G
core0. At the end of the task, the DPUCZDX8G
generates an interrupt to signal the completion of a task, and bit0 in reg_dpu_isr is
set to 1. The position of the active bit in the reg_dpu_isr depends on the number of
DPUCZDX8G cores. For example, when DPUCZDX8G core1 finishes a task while DPUCZDX8G core0 is still processing, reg_dpu_isr
The DPU IP may be configured to instantiate 1-4 cores (see DPU Configuration). The IP wrapper for the configured DPU will have up to
dpux_interrupt signals, corresponding to the
number of cores. These signals must be routed through a concat block, and then be
connected to the PS as illustrated in the following image.
- irq7~irq0 corresponds to pl_ps_irq0[7:0].
- irq15~irq8 corresponds to pl_ps_irq1[7:0].
