==============
Intel 80x86_64
==============

All x86_64 source reside in lower-level common, chip-specific, and architecture-specific
directories.

arch/x86_64/src/common/ Directory
=================================

This directory holds source files common to all x86_64 architectures.

Architecture-Specific Directories
=================================

Architecture-specific directories hold common source files shared for by
implementations of specific x86_64 architectures.

``intel64``
  This directory holds logic appropriate for any instantiation of the 64-bit
  intel64 architecture.

Chip-Specific directories
=========================

The same x86 architecture may be realized in different chip implementations.
For SoC chips, in particular, on-chip devices and differing interrupt
structures may require special, chip-specific definitions in these chip-
specific directories.

``broadwell``
  This is the implementation of NuttX on the Intel Broadwell processors.
