. There are also three 16-bit segment registers (see figure) that allow the 8086 CPU to access one megabyte of memory in an unusual way. rather than concatenating the segment register with the address register, as in most processors whose address space exceeds their register size, the 8086 shifts the 16-bit segment only four bits left before adding it to the 16-bit offset (16 × segment + offset ), therefore producing a 20-bit external (or valid tive or physical) address from the 32-bit segment:

the last curly brace is followed by a ";" End. In my opinion,JAVA refers to these things in order to make the program easier and easier for editors and readers. this week's blog post I choose to describe the problems that have previously remained, but also feel that I will deepen the impression here again, will further understand these grammatical points. And what about it! I am also very grateful to the teacher last week for me to provide a link to the internal class syntax, thank you teacher!

set 64-bit version. Originally proposed by AMD and named X86-64, it is now supported by most of the AMD64 and Intel64 processors. However, the system still runs only the 32-bit versions of these operating systems, but newer versions of Linux and Windows support this expansion.IA32 expands to 64-bit because the length of the machine defines the range of virtual addresses that the program can use, while the 32-bit word length is the virtual address space of 4GB. For applications that need to hand

address. The segment address and offset address are sent to a part called the address divider through the internal bus. The address divider combines two 16-bit addresses into a 20-bit physical address. The address divider sends 20-bit physical addresses to the input/output control circuit through the internal bus. The Input/Output Control Circuit sends 20-bit physical addresses to the address bus. 20-bit physical address is transferred to the memory by the address bus

. 4.4 Data registers can be split For example, ax can be divided into AH (high register) and Al (low register ). MoV Al, 15; set the low position to 8; MoV ah, 0; this sets the high position to 0; The value of ax is changed to 0008. The byte is counted as byte. A byte consists of 8 bits, which can be contained in 8-bit registers. Word: it is recorded as word. A word consists of two bytes. These two bytes are called the high byte and low byte of the word respectively. The address divider uses the

* 16 + offset addressYou can use the segment address and offset address to synthesize the physical address. The essential meaning of "segment address * 16 + offset address = physical address" When the CPU accesses the memory, it adds a base address (segment address * 16) and an offset address relative to the base address to give the physical address of the memory unit. Segment Concept When programming, you can think of memory units with consecutive addresses as a segment, and use segment addr

object of its own type. In the same package, the different classes defined in each program can be called between each program. You cannot have two classes of the same class name in the same package. A static method is a method that cannot manipulate an object, but it can operate on a static instance domain in the same class. Access-time class name. + static method name. A static domain belongs to a class that does not belong to any independent object. This is the property reference and this ()
