High-Speed Debug Port is a protocol that provides debug and trace for the programmable logic (PL), processing system (PS) and the AI Engines. HSDP can use gigabit transceivers on the device to provide better performance than the JTAG interface.
As HSDP is a protocol, the transaction layer is handled by the Debug Packet Controller (DPC) and the link layer can be one of the four interfaces listed below:
- HSDP Aurora (hardened Aurora IP)
- CPM PCIe Controller
- PL Aurora (soft Aurora IP)
