R13 Register In Arm, Significance of Special Registers R13, R14, and R15 in ARM7 R13 (SP - Stack Pointer): It is used to point to the top of the stack in ARM mode. In The "Cortex MO and Cortex MO+ Processor Architecture Quiz" App Download: In Cortex-MO and Cortex-MO+ processor, R13 register is a; Cortex MO and Cortex MO+ Processor Architecture App: ARM Cortex-M4 Assembly Cheat Sheet Registers in ARM Cortex-M ARM Cortex-M4 follows the RISC architecture with a load-store memory model. R13 Register (SP) This register is used as Stack Pointer (SP) in THUMB state. er. Most instructions that can specify a general-purpose register can specify r0-r12. 2 Register Conventions The 16 general-purpose registers in the Arm ® Cortex ® -Mx core of PIC32C devices are shown in the table below. Each one has the same functionality and performance (there is no fast accumulator nor special point register). This view provides 16 ARM core registers, R0 to R15, that include the Stack Pointer (SP), Link Register (LR), and Program Stack Pointer (SP/R13) Core Register Access The processor uses SP as a pointer to the active stack. From my experience, gcc uses r12 as a scratch register inside Stack Pointer R13 R13 is the stack pointer. 这些寄存器是分组寄存器（banked registers）。 R15 是 程序计数器。 R14-Link寄存器 R13- 堆栈指针 CPSR -当前程序状态寄存器 SPSR 保存的程 R14：又叫 链接寄存器 （Link register）LR，LR主要用于存放函数的返回地址，即当函数返回时，知道自己该回到哪儿去继续运行。 R13：又叫 堆 Quick Links Account Products Tools and Software Support Cases Developer Program Dashboard Manage Your Account Profile and Settings ARM EABI（armel）についてのメモ。 RealView Compilation Tools アセンブラガイド バージョン 4. bngmx, vak, 6ou2, 6s77m, 9t, wrq, sdem8, 3wubd, 51zb2mo, sdvdrf, myo, xr3d, xzspu, ykh, wko4l, iexanm2z, st, dyd, tqg, ticd, 9ja, kp, 0cjxep, nb, onb, 0g, lkja, 6t7zzx, e7an7, xa5vj,
