, it consists of analog signal conditioning circuit, A/D conversion circuit, display circuit and 485 communication circuit. The signal must be processed before it enters the/D converter. analog signal processing is one of the important factors affecting the system performance. signal quality should be taken into consideration during design to improve the signal-to-noise ratio and minimize distortion. In the design, the potentiometer is used in the conditioning circuit for fine-tuning, and the vo

physical memory managed by hardware. The operating system uses the memory management unit of the microprocessor to process real-time conversion between virtual addresses and physical addresses. The advantage of this virtual memory method can be seen from the complex address space of MS-DOS systems. Once the requested Ram exceeds the 640-kb limit originally designed by the PC, the programmer will have to make plans like expanding the memory to increas

We need to sort out some theoretical or superficial knowledge, so we have time to sort out this rough comparison, let's take a look at the features of these two mainstream processors from the other side! DSP: DSP ( digital singnal processor ) is a unique microprocessor. It has its own complete command s

procedure. During this operation, the processor returns the instruction pointer, the return code snippet selector, and the eflags image to the EIP, CS, and EFlags registers, respectively, from the stack, and resumes the program or procedure that executed the interrupt. In protected mode, the operation of the IRET directive depends on the settings of the NT (nested task) and VM flags in the EFlags register, and the settings of the VM flags in the eflags image stored in the current stack.

Usually the hardware and software options include: processor, hardware components, operating systems, programming languages, software development tools, hardware debugging tools, software components, etc. In the above selection, the processor is usually the most important, and the operating system and programming language are also critical. The selection of the processor often limits the sele

Most Linux systems run on PC platforms, but Linux is also very stable as an embedded system. This article depicts an overview of an embedded system and shows how embedded system products use Linux. The story of an embedded system older than Moses The history of computers used to control devices or embedded systems is almost as long as that of computers. In the field of communication, computers were used in electronic telephone switches in the late 1960s S, known as the "storage program control"
