Intel 80x86 Addressing mode

With further research, we will gradually come into contact with your computer configuration patterns, and design principles. In these, solving a computer is a very important concept that we need to understand very well.I. Preliminary heats:(1) CountBefore contacting the addressing method, we also need to understand the concept of the operand, depending on how the operand is stored, we can divide the operand into 3 classes,1. Immediate operation number: The operand is included in this instruction

Basic use of Intel processor-based prefetch commands

, %rcx)fadd %st(0), %st(1)fcmove %st(1), %st(0)faddp %st(0), %st(1) fstpl (%rdi, %rax)add $(8 * 1024), %rcxadd $8, %raxsub $1, %r8jne opt_processsub $1, %r9jne opt_loopret The only difference between opt_calc and naive_calc is that opt_calc has two prefetch commands. Below are the test functions in C language: #include In order to increase the calculation cycle, multiply by 2. The performance of opt_calc can be increased by about 8% to 20% in Mac Mini

Intel te28f320c3ba100 flash read/write function FAQ

Q1 # What is the role of the define barrier () _ ASM _ volatile _ ("": "Memory") Macro? A: This macro is defined in the blob-2.0.5-pre2/include/BLOB/util. h and is used multiple times in the blob-2.0.5-pre2/src/BLOB/intel16.c. According to expert guidance from the oldlinux.org forum, I found the macro explanation in section 5.3.2 of ulk2: the macro, however, forbids the complier to reshuffle the instructions. that is, the macro prohibits the compiler from re-arranging the (assembly language) com

View Linux CPU Information

We can use/proc/cpuinfo to view CPU information. This file contains the data section of each processor on the system. There are six entries in the/proc/cpuinfo description for multi-core and super-thread (HT) technical checks: processor, vendor id, physical id, siblings, core id and cpu cores. (1) processor: including the unique identifier of the logical processor. (2) physical id: including the unique id

At&t and Intel assembly formats

1. In intel format, most of them use upper-case letters (both in lower case) and lower-case letters in att format. 2. In att format, Register names must be prefixed with "%", which is not required in intel. 3. The original operation of the command is different from that of the destination operand. For example, if the eax value is passed into the EBX command, in Inte
