Hardware/Software Interfaces

  • Patrick R. Schaumont


The objective of a hardware/software interface is to enable communication between software and custom hardware. The software runs on a microprocessor, while the custom hardware is attached to that microprocessor. We will consider how to implement stable data transfers by synchronizing software and hardware. Next, we will discuss the various implementations of hardware/software interfaces, including memory-mapped interfaces, coprocessor interfaces, and custom-instruction interfaces.
