coherent traffic between the N1 SoC and an accelerator daughterboard, and PCI Express Gen 4
development.
Using this book
This book is organized into the following chapters:
Chapter 1 Introduction
This chapter introduces the Arm Neoverse N1 System Development Platform (N1 SDP).
Chapter 2 Hardware description
This chapter describes the N1 SDP hardware.
Chapter 3 Configuration
This chapter describes the powerup and configuration process of the N1 SDP.
Chapter 4 Programmers model
This chapter describes the programmers model of the N1 SDP.
Appendix A Signal descriptions
This appendix describes the signals that are present at the N1 SDP ports.
Appendix B Revisions
This appendix describes the technical changes between released issues of this book.
Glossary
The Arm® Glossary is a list of terms used in Arm documentation, together with definitions for those
terms. The Arm Glossary does not contain terms that are industry standard unless the Arm meaning
differs from the generally accepted meaning.
See the Arm® Glossary for more information.
Typographic conventions
italic
Introduces special terminology, denotes cross-references, and citations.
bold
Highlights interface elements, such as menu names. Denotes signal names. Also used for terms
in descriptive lists, where appropriate.
monospace
Denotes text that you can enter at the keyboard, such as commands, file and program names,
and source code.
monospace
Denotes a permitted abbreviation for a command or option. You can enter the underlined text
instead of the full command or option name.
monospace italic
Denotes arguments to monospace text where the argument is to be replaced by a specific value.
monospace bold
Denotes language keywords when used outside example code.

<and>
Encloses replaceable terms for assembler syntax where they appear in code or code fragments.
For example:
MRC p15, 0, <Rd>, <CRn>, <CRm>, <Opcode_2>
SMALL CAPITALS
Used in body text for a few terms that have specific technical meanings, that are defined in the
Arm® Glossary. For example, IMPLEMENTATION DEFINED, IMPLEMENTATION SPECIFIC, UNKNOWN, and
UNPREDICTABLE.
Timing diagrams
The following figure explains the components used in timing diagrams. Variations, when they occur,
have clear labels. You must not assume any timing information that is not explicit in the diagrams.
Shaded bus and signal areas are undefined, so the bus or signal can assume any value within the shaded
area at that time. The actual level is unimportant and does not affect normal operation.
Clock
HIGH to LOW
Transient
HIGH/LOW to HIGH
Bus stable
Bus to high impedance
Bus change
High impedance to stable bus
Figure 1 Key to timing diagram conventions
Signals
The signal conventions are:
Signal level
The level of an asserted signal depends on whether the signal is active-HIGH or active-LOW.
Asserted means:
• HIGH for active-HIGH signals.
• LOW for active-LOW signals.
Lowercase n
At the start or end of a signal name, n denotes an active-LOW signal.
