	Part II. The eCos Hardware Abstraction Layer (HAL)

Chapter 1. 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 documentation, 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.
