Hardware Platform Selection Processor Selection The core component of the embedded system is various types of embedded processors. According to incomplete statistics, the total number of embedded processors worldwide has exceeded more than 1000, with more than 30 popular systems. However, unlike the global PC market. No

In the above selection, the processor is often the most important, and the operating system and programming language are also critical. The selection of processors often limits the selection of operating systems, and the selection of operating systems also limits the selection of development tools.

Article title: Linux implementation features based on the i386 architecture-memory and process. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Summary ?? The Linux kernel design should take into account the implementation on a variety of different microprocessor, as well as the implementation on 64-bit

C # parallel programming-related concepts, For more information, see the C ++ concurrent programming high-level tutorial. Background Today's computers have at least one dual-core microprocessor, which is very common with quad-core and eight-core computers. The era of having multiple kernels on a single processor is approaching, modern microprocessor provides a new multi-core architecture. Therefore, it is v

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. At present, most of the applications are specially designed to meet the requirements of high performa

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

I. 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

after high-level language statements are categorized. To make the hardware more and more complex, the cost is correspondingly improved. For complex operations, the microprocessor provides programmers with a similar variety of registers and machine instruction functions. Also through the micro-program stored in the read-only memory (ROM) to achieve its very strong function, proud processing after each instruction to perform a series of primary instruc
