A code sequence made up multiple instructions and specifying an offset from a base address is identified in an object file. The offset from the base address corresponds to an offset location in a memory configured for storing an address of a variable…
ref:http://kmittal82.wordpress.com/2012/02/17/armthumbthumb-2/ A few months ago I gave a presentation titled “Introduction to the ARM architecture”. One of the most well received sections of that was a bit where I explained the difference between the…
Executing a Next Instruction Access Intent instruction by a computer. The processor obtains an access intent instruction indicating an access intent. The access intent is associated with an operand of a next sequential instruction. The access intent…
The Cortex-M3 supports the Thumb-2 instruction set. This is one of the most important features of the Cortex-M3 processor because it allows 32-bit instructions and 16-bit instructions to be used together for high code density and high efficiency. It…
接着上一篇去讲,回到JavaCalls::call_helper()中: address entry_point = method->from_interpreted_entry(); entry_point是从当前要执行的Java方法中获取的,定义如下: 源代码位置:/openjdk/hotspot/src/share/vm/oops/method.hpp volatile address from_interpreted_entry() const{ return (address)Orde…
Thumb指令集 ]的问题而提出的,它具有16为的代码密度.Thumb不是一个完整的体系结构,不能指望处理程序只执行Thumb指令而不支持ARM指令集.因此,Thumb指令只需要支持通用功能,必要时,可借助完善的ARM指令集,例如:所有异常自动进入ARM状态. 在编写Thumb指令时,先要使用伪指令CODE16声明,而且在ARM指令中要使用BX指令跳转到Thumb指令,以切换处理器状态.编写ARM指令时,可使用伪指令CODE32声明. [1].代码密度:单位存储空间中包含的指令的个数.例如 AR…
