HAL

Nios II Hardware Abstraction Layer (HAL) is a well defined software layer that forms a clear distinction between application and device-level software. The HAL also provides services such as file descriptors, I/O control, and buffering, which are required by the ANSI C library functions, so that your HAL driver does not need to provide these functions.
