7.1.1. SoC Abstraction Layer (SoCAL)

The SoC Abstraction Layer (SoCAL) presents the software API closest to the actual HPS hardware. Its purpose is to provide a logical interface abstraction and decoupling layer to the physical devices and registers that comprise the hardware interface of the HPS.

The SoCAL provides the benefits of:

  • A logical interface abstraction to the HPS physical devices and registers including the bit-fields comprising them.
  • A loosely coupled software interface to the underlying hardware that promotes software isolation from hardware changes in the system address map and device register bit field layouts.
