ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor extensions: • The standard System Control coprocessor (coprocessor 15), which is used to control memory system components such as caches, write buffers, Memory Management Units, and Protection Units. • The Vector Floating-point (VFP) architecture, which uses coprocessors 10 and 11 to supply a high-performance floating-point instruction set. • The debug architecture interface (coprocessor 14), formally added to the architecture in ARM v6 to provide software access to debug features in ARM cores, (for example, breakpoint and watchpoint control).-ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor

一本很不错的嵌入式系统书籍，是一本很好的入门教材！-a very good embedded systems books, is a good primer!

应用背景CANopenNode is an opensource CANopen Stack. CANopen is the internationally standardized (EN 50325-4) CAN-based higher-layer protocol for embedded control system. For more information on CANopen see http://www.can-cia.org/ Stack is written in ANSI C in object-oriented way. Code is documented. License is LGPL. It includes Example for CANopen Input/Output device and simple CANopen master. Variables (communication, device, custom) are ordered in CANopen object dictionary and are accessible from both: C code and from CAN network. Code includes:  - CANopen Stack for multiple microcontrollers with documenation.  - Working examples of simple Input Output CANopen device for all microcontrolers.  - Working CANopen master device with HTML interface to CANopen: CAN log, Emergency log, SDO master, NMT master, Custom CAN message.
