Chapter 6. Introduction

This is an initial specification of the eCos Hardware Abstraction Layer (HAL). The HAL abstracts the underlying
hardware of a processor architecture and/or the platform to a level sufficient for the eCos kernel to be ported onto
that platform.

Caveat: This document is an informal description of the HAL capabilities and is not intended to be full documen-
tation, although it may be used as a source for such. It also describes the HAL as it is currently implemented for
the architectures targeted in this release. It most closely describes the HALs for the MIPS, I386 and PowerPC
HALs. Other architectures are similar but may not be organized precisely as described here.
