\begin{preface}

This controller is born of necessity.  As long as Xilinx's proprietary IP

makes it difficult to access memory, providing only access via the proprietary

AXI bus, some conversion will be necessary for anyone who wishes to use a

wishbone interface.

A special shout out and thanks go to Stephan Wallentowitz, for his first

draft of such a converter, and to Olofk for encouraging me to write it.

%

% Introduction

%

% This section contains the introduction to the core, describing both its

% use and its features.

%

% What is old

% What does the old lack?

% What is new

% What does the new have that the old lacks

% What performance gain can be expected?

\chapter{Architecture}\label{ch:arch}

% This section describes the architecture of the block.  A block level diagram

% should be included describing the top level of the design.

\chapter{Operation}\label{ch:ops}

% This section describes the operation of the core.  Specific sequences, such

% as startup sequences, as well as the modes and states of the block should be

% described.

%

\chapter{Clocks}\label{ch:clocks}

% This section specifies all of the clocks.  All clocks, clock domain passes

% and the clock relations should be described.
