ARM has 31 general-purpose 32-bit registers plus 6 program status registers. Some registers are shared for all work modes, and some are specifically for a certain mode of operation.

In fact, there is no standard answer to this question, mainly because some popular notebook brands will launch different product models, positioning different users. If on the whole, we can through the major notebook brand market share, roughly understand which brand is

Cinebench R15 Run points:
In accordance with the previous practice, first of all, we still use cinebench R15 to run the test, after the test of multi-threaded performance of 196CB, graphics rendering ability test for 27.63FPS, in the same kind of processor score is a higher one, relatively good.

On the x86_64 platform, the parameters of Linux are passed through the following 9 registers, respectively: Rdi,rsi,rdx,rcx,rax,r8,r9,r10,r11. In the Pre_handler function, we can get the Register group variable, through the Register group variable, we can get the second parameter value passed by the Create_empty_buffers function through the RSI register. For the Linux-2.6.23 version, the registers in the function call process are defined as follows in the stack:

Each function system allocates a stack frame, and the system is automatically retracted after the execution is completed. Each function thinks r0~r15, CPSR and so on CPU related re

I have recently written some optimizations for string functions and used x64 Assembly. I am also the first time in this article, so I would like to share with you.
X86: Also known as x32, it indicates the Intel x86 architecture, that is, Intel's 32-bit 80386 assembly instruction set.
X64: EM64T of AMD64 and Intel, excluding IA64. You can search for the differences between the three.

The value is equal to the address +8 of the currently executing instruction (because there is a more decoding phase between the fetch and the execution). The PC always points to the post two instruction address that is running, which is the address +8 of the current execution instruction.???? 5. Status Register:Figure 1-

In this case, DEVB users must first perform updata operations on the modified file. If two users modify the same location of the file soc_2, after the DEVB user executes updata, the system will merge the local soc_2 and the downloaded soc_2 from the server to a file, the file icon is marked with a yellow exclamation mark, indicating a fil

Difference between von norann Implementation Harvard Implementation of ARM
Von norann implementation: data items and instructions share the same bus.
Harvard implementations: It uses two different buses.
Load-store architecture:
Load: Memory ----- (load instructions copy data) -------> registers in Core
Store: registers ---- (store instructions copy data) ------> memory
There are no data processing instructions that directly manipulate data in memory.
Register:
There are 18 active registers
searched the internet and found no ide supporting asm64, or even no editor. Therefore, the simplest method is to modify the MASM syntax file of editplus on your own. This is also the method I used, at least to obtain syntax highlighting. Of course, if you are too lazy to do it, use notepad.Without IDE, You need to manually enter a lot of parameters and options for each compilation, just do a batch.

ARM has a total of 37 registers, can work in 7 different modes. The following descriptions are categorized according to the above figure: the R0-R7 registers are shared for all modes, with a total of 8. R8-r12 in the packet register, the fast interrupt mode has its own set of registers, and other modes are shared, so there are 10. R13,r14 in the packet register, in addition to user mode and system mode sharing, other modes of each group, so there are 2*7-2 = 12.
