Preface About this book This is the Technical Reference Manual (TRM) for the CoreSight SoC components. Product revision status The rnpn identifier indicates the revision status of the products described in this book, where: rn Identifies the major revision of the product. pn Identifies the minor revision or modification status of the product. Intended audience This book is written for the following audiences: • Hardware and software engineers who want to incorporate CoreSight SoC into their design and produce real-time instruction and data trace information from an ASIC. • Software engineers writing tools to use CoreSight SoC. This book assumes that readers are familiar with AMBA bus design and JTAG methodology. Using this book This book is organized into the following chapters: Chapter 1 Introduction Read this for an overview of the CoreSight components. Chapter 2 Functional Overview Read this for a description of the major functional blocks and the operation of CoreSight SoC. Chapter 3 Programmers Model Read this for a description of the memory map and registers. Chapter 4 Debug Access Port Read this for a description of the Debug Access Port (DAP) components. Chapter 5 ATB Interconnect Components Read this for a description of the Advanced Trace Bus (ATB) interconnect components. Chapter 6 Timestamp Components Read this for a description of the timestamp components. Chapter 7 Embedded Cross Trigger Read this for a description of the Embedded Cross Trigger (ECT) components. Chapter 8 Trace Port Interface Unit Read this for a description of the Trace Port Interface Unit (TPIU) components. Chapter 9 Embedded Trace Buffer Read this for a description of the Embedded Trace Buffer (ETB) components. Chapter 10 Granular Power Requestor Read this for a description of the Granular Power Requester (GPR) components. ARM DDI 0480D Copyright © 2011, 2012 ARM.
