operate in different ways, their segment addresses are different. However, after the program is compiled, the offset address within his program is determined (as if we were able to print the offset address of the main function, indicating that the address is deterministic). And each program has a maximum of 64K of the program segment and 64K data segment and the stack segment of the mixing segment. So each time the system is allocated, each program is assigned a fixed size but different memory

Protection Mode Overview From: http://www.pagoda-ooos.org/ In the 8086/8088 era, there was only one operating mode for the processor. At that time, this mode was not named because there were no other operating modes. Since 80286 to 80386, the processor has added two more operating modes: protection mode PM (Protected Mode) and system management mode SMM (System Management Mode). Therefore, 8086/8088 of the

Background Sometimes a server deploys both Nginx and other Web services, which in turn consumes 80 of the server's port, and the Web service uses a non-80 port.

.A20 GATE origin [1] In 8086/8088, there are only 20 address lines, so the address you can access is 2^20=1m. But since 8086/8088 is a 16-bit address pattern, the range of addresses that can be represented is 0-64k, so in order to access 1 m of memory, Intel takes a segmented pattern. That is: Physical address = 16-bit segment address *16 + 16-bit offset However, this approach raises new problems, and the m

UTC nanoseconds, and just started in this big circle, writing data can be successful but cannot be queried because of the wrong time. Java does not have a direct UTC nanosecond method, only System.currenttimemillis () gets the millisecond method. In fact, according to the millisecond and nanosecond conversion units, directly in the System.currenttimemillis () plus six 0 can be. Given the fact that there will be concurrent writes, the same data may be written within a millisecond, and the 6-bit

Embedded Processor stageThe biggest difference between an embedded microprocessor and a general-purpose microprocessor is that an embedded microprocessor mostly works in an application-oriented system designed by the equipment manufacturer.

From the programming point of view, the ARM microprocessor has two working states and can switch between them: (1) arm status. At this time, the processor executes the 32-bit arm command (2) thumb status. At this time, the processor executes a 16-bit, semi-aligned thumb command (to be compatible with the old chip) During the process of running the program, you can switch between the two States. The change of the processor's working status does not aff

Arm working mode: ARM microprocessor supports seven working modes: 1.User Mode (usr)Used for normal Program Execution 2.Fast interrupt mode (FIQ)For high-speed data transmission 3.IRQ) For normal interrupt handling 4.Management Mode (SVC)Operating system protection mode (high permission), reset and software interruption 5.Data Access termination mode (ABT)This mode is used for virtual memory and storage protection when data or command prefetch is t

communication protocol operation. The MAC address is expressed in three bits, that is, eight devices can be addressable in one micro-network (the number of connected devices is actually unlimited, but only eight devices can be activated at the same time, one of them is primary, and seven are slave ). Figure 1 shows the topology of a Master/Slave Device in the micro-network. In addition, the Bluetooth system supports point-to-point communication to form a distributed network, that is, one master

instructions to calculate and control the system, and each CPU specifies a series of instruction systems that match its hardware circuitry at design time. The strength of instructions is also an important indicator of CPU, and instruction set is one of the most effective tools to improve the efficiency of microprocessor. From the current mainstream architecture, instruction set can be divided into complex instruction set and thin instruction set two
