-purpose registers or segment registers of the CPU (except CS), the 16-bit register operand can be ax, BX, CX, DX, SI, DL, SP, BP, DS, SS, and es,8 bit registers can be Al, AH, BL, BH, CL, CH, DL, DH. Because the number of access operations within the CPU, do not need to access the memory of the second implementation bus cycle, so the execution speed is very fast, in addition to a small number of general-purpose registers, coding required less bits, s

It took nearly two days to upload the space-based documents in batches. The original document was originally stored in the folder under the website directory as a file, and then stored in the bytea field of PostgreSQL. This field is equivalent to the blob or clob field of oracle, data is stored in a second-level system, with a maximum of 2 GB of data. I am not familiar with PHP programming. I have read and write the bytea FIELD IN THE postgesql database only after reading a large amount of ref

Each record is stored in three rows: the original currency, the integrated standard currency, and the integrated report currency. Therefore, the storage space coefficient is 2x3 = 6. The virtual account balance view v_gl_virtualbalance. The original table t_gl_accountbalanceunion has been deprecated. Auxili

classification rule set, each rule corresponds to the judgment condition from the root to the leaf node path and the category in the leaf node. Then, the rule set is used to classify unknown tuples.Currently, the main decision tree classification algorithms include: In the late 1980s s and the early 1980s S, machine learning researcher I. Ross. Quinlan developed the decision tree algorithm called ID3. Quinlan later proposed C4.5. In 1984, several statisticians (L. Breiman, J. Friedman, R. Qlshe

Generally, the function returns pop {r7, pc} Or bx lr (bx and B are similar to jmp for jump instructions, but bx can specify whether the jump area is thumb or arm ).Our goal is to perform the following operations

IntroductionIn this chapter, we are going to discuss these two basic questions for 8086CPU. Although the discussion is based on 8086CPU, these two basic questions are common and exist for any processor.The collection of Reg includes: AX, BX, CX, DX, ah, AL, BH, BL, CH, cl, DH, DL, SP, BP, Si, di;The Sreg collection includes: DS, SS, CS, es.8.1 bx, Si, Di, bpIn 8086CPU, only these 4 registers (

In the first chapter, we introduce the basic knowledge of assembly language, in the second chapter we mainly introduce registers.The main components of the CPU are registers, in the 8086CPU there are 14 registers, respectively: AX, BX, CX, DX, SI, DI, SP, BP, IP, CS, SS, DS, ES, PSW. All registers of 8086CPU are 16-bit and can hold two bytes. The 4 registers, AX, BX, CX, DX, are typically used to hold gener

In the same program, a label or variable can be defined only once.Labels have three properties: segment, offset, type (near Ptr,word ptr,far Prt,dword PTR)??One. Numeric loopback operator: TYPE, Legnth, SIZE, OFFSET, SEG1.? TYPE???? Expression_r (or label) If the expression is a variable, echo the type of the variable in bytes: DB is 1, DW is 2, DD is 4 ...If the expression is a label, the value of the label type is echoed: near is-1, far is-2.If the expression is constant, echo 0.Array??

pointer is also common to all tasks. Therefore, you also need to save them. For global variables, because they are usually fixed in the memory, the space occupied by each task is completely independent, so they do not need to be saved. In the x86 environment, there are 14 16-bit CPU registers to be saved; 8 general-purpose registers (ax, BX, CX, dx, SP, BP, Si, Bi) four segment registers (CS, DS, es, SS), one instruction pointer IP address and one fl

Recently, in order to review graph programming in TC, I wrote a program for Tetris, which can implement the functions of the common Tetris program. Now I will post the source code for everyone to share, due to my limited level, you are welcome to raise any questions. In addition, the decrease speed of the square in this program cannot be changed. If you have any good solutions, please contact me.

Assembly languages depend on the architecture. In Linux, the compiled assembly by GCC is an ATT syntax assembly by default. This article mainly introduces ATT Assembly: operand length, immediate number representation method, register reference, operand sequence, symbol constant, memory Reference. 1. The length of the operand The length of the operand is expressed by the symbol after the instruction in B (byte, 8-bit), w (word, 16-bits), L (long, 32-bits ), for example, "movb % Al, % Bl", "mov
