how to register tld

Four data registers (eax, EBX, ECx, and EDX)2 address changes and pointer registers (ESI and EDI) 2 pointer registers (ESP and EBP)Six segment registers (ES, Cs, SS, DS, FS, and GS)1 Instruction Pointer register (EIP) 1 flag register (eflags) 1. Data RegisterData registers are mainly used to save information such as the operands and operation results, thus saving the time required to read the operands

addressable range, that is, the amount of memory that can be supported. If the address bus is too narrow, the addressable range will be small. If the address bus is designed to be 16 bits, the addressable space would be 2 ^ 16 = 64kb, which was considered insufficient at the time; intel eventually decided to set 8086 of the address space to 1 m, that is, 20-bit address bus. If the address bus width is greater than the data bus, it may cause some trouble. Alu cannot compute the address data in a

1,CPU Interface control Register, GICC_CTLR: Controls the Register, controls whether to escalate interrupts to the processor;2. Interrupt First Mask Register, GICC_PMR: Interrupt priority Masking Register, we can understand that the processor is not the average person, not everyone can disturb, this

In C + +: (1) The Register keyword cannot define a variable in the global, or it will be prompted as an incorrect storage class. (2) when the Register keyword is declared in a local scope, the address can be taken with the operator, and once the address operator is used, the defined variable is forced to be stored in memory. In C: (1) The Register keyword ca

int i;for (i=0; iIn order to solve this problem, it is possible to put frequently used variables in the general register of the CPU, so that the use of the variable without access to memory, directly from the register to read, greatly improve the efficiency of the program operation.To deepen the understanding of register variables, it is necessary to speak about

Intel X86 architecture The Pentium i-386 is a 32-bit CISC (Complex Instruction computer) processor, but the aplha is based on Risc (short instruction computer ).CodeBut the principles are similar. The processor has many General registers. Registers are storage locations that are of special use in the microprocessor itself. Access registers are much faster than accessing other types of memory. Some registers are common, while others are of special use. General registers are used to store th

Seeing him like this, I suggested to him the use of WPS table function automatic Rollup, and hand-set the method of the function to tell him.I.

Comments: First, let's talk about common registers. 1 CPU Composition CPU can be roughly divided into the following three parts:(1) The arithmetic logic Part ALU (arithmetic logic unit) is used for arithmetic and logical operations.(2) control logic.(3) working register, each register is equivalent to a storage unit in the memory, but it is fast to access. It is used to store information required or obtaine

IAA32 process call register protection rules Because of the shared nature in the operating system, registers become a type of resource sharing for various processes or processes. When a process call occurs, if the caller needs to use the value in a register, but the content of this register is likely to be modified during the invocation of the caller, therefore,
