This chapter covers ARM data transfer instructions such as load and store, pseudo instructions, data transfer instruction format, data transfer addressing mode such as register indirect addressing and pre-indexed addressing, data representation in memory, and several examples related to data transfer ...
左边是程序的C代码, 右边是在ARM上得到的汇编程序. 我们的关注点在循环的部分, 即: 500 这里必须清楚ISA(instruction set architecture, 指令集), microarchitecture(微架构, 也称处理器架构)的区别和联系 ISA是硬件和软件之间的契约, 一种接口描述 ISA定义了一套指令, 并指明了每条指令的用处, 但不会指明每个指...
In your example, LDUR R3, [R1, #8] this instruction will load toR3the value pointed byR1plus8bytes. This is what the ARM Reference Manual means bybyte offset. So ifR1holds the value0x50, this will load the value stored at address0x58. The value ofR1will not be modified. The instru...
Arm introduced its ARMv8 64-bit architecture in 2011. Rather than extend its 32-bit instruction set, Arm offers a clean 64-bit implementation. To accomplish this, the ARMv8 architecture uses two execution states, AArch32 and AArch64. As the names imply, one is for running 32-bit code a...

aARM instruction set architecture, ARMv7. This is a modern RISC architecture with many advanced features. The formalization is detailed and extensive. Considerable tool support has been developed, with the goal of making the model accessible and easy to work with. The model and supporting tools ...
This operation is not required by the ARM architecture, and code must not rely on Wait For Interrupt operating in this way. Using WFI to indicate an idle state on bus interfaces A common implementation practice is to complete any entry into power-down rout...

These operate on the general-purpose registers. In many cases, the result of the operation must be put in one of the operand registers, not in a third register. There are fewer data processing operations available than in ARM state. They have limited access to registers r8 to r15. ...
This manual describes the A and R profiles of the ARM architecture v7, ARMv7. It includes descriptions of the processor instruction sets, the original ARM instruction set, the high code density Thumb instruction set, and the ThumbEE instruction set, that
