Data-driven platform characteristics capture and discovery for hardware accelerators

An example computing system includes: a processing system, a hardware accelerator coupled to the processing system, and a software platform executing on the processing system. The hardware accelerator includes: a programmable integrated circuit (IC) configured with an acceleration circuit having a static region and a programmable region; a memory in the programmable IC configured to store metadata describing interface circuitry in at least one of the static region and the programmable region of the acceleration circuit. The software platform includes program code executable by the processing system to read the metadata from the memory of the hardware accelerator.
