competitive in this rapidly growing market. However, users benefit from low prices. Many of the structural features of early PCs remain in modern PC systems. For example, Intel's most advanced Pentium Pro processor retains the Intel 8086 addressing model. When Linus Torvalds started to write Linux, he chose Intel 80386 PC, which was the most widely used and reasonably priced at the time.. 1 typical PC motherboard. From the outside of the PC, the most striking is the chassis, keyboard, mouse and

, 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

be as accurate as possible, in order to ensure easy to understand, may not reach the academic level of accuracy.3) This post emphasizes knowledge and understanding. And in reality, is to spend six hundred or seven hundred to buy a i3, or 1000 buy a i5, the specific situation of the specific analysis, there is no fixed answer.4) If it is local tyrants, just a ' cool ' word. Do not seek cost-effective, only the most expensive. This post is not recommen

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

Original article: http://blog.163.com/liuhonggaono1@126/blog/static/10497901201183004839992/ These days we are preparing to look for a job. 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

implementation features based on the i386 architecture Preface ?? This article discusses the features of linux on the cpu of the i386 system. This article introduces the interrupt mechanism, segment-and-page management of memory, and the hardware mechanism provided by task switching under the i386cpu protection mode, compare the differences between the specific implementation features of Linux and the i386 design intent. Describes how to set the Linux interrupt vector table, initialize the inte

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

integrated into a computer by strange special commands and I/O devices. The microprocessor has changed all of this by providing small, low-cost, and CPU engines for building large system modules. It proposes a fixed hardware architecture connected by peripherals through a bus and a general programming model called programming. The software is also proposed with the hardware. Initially, writing and testing software only had simple programming and de

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"

Because the actual situation of transaction records are often stored on the external storage, such as databases or other formats of the file, in each calculation of the candidate count will need to compare the candidate with all transactions, it is known that access to the external memory is often relatively low efficiency, so Apriori joined the so-called pruning step, The candid

1.1 Overview of embedded systems 1.1.1 definition and composition of Embedded Systems Embedded systems are application-oriented, computer-based, and can be used to reduce hardware and software. They are suitable for application systems, dedicated computer systems with special requirements for functions, reliability, cost, volume, and power consumption. The essential difference between an embedded system and a general computer system is that the system applications are different. an embedded syst
