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

?? 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

The Sandy BRIDGE-E processor became a new generation of kings without any suspense after the recent release. It is a number of pins close to the previous generation of products twice times the processor, but it does follow the framework of SNB and to expand it, on the size of the specification is absolutely the current top level products, we do not need to guess its performance, Just know how tough it can be.

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"
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
ARM is a well-known enterprise in the microprocessor industry. It has designed a large number of high-performance, low-cost, and low-energy-consuming Proteus processors, related technologies and software. The technology features high performance, low cost, and low energy consumption. It is applicable to multiple fields, such as embedded control, consumption/education multimedia, DSP, and mobile applications.

Two mainstream chips
The core processors of arm9-and MIPS are currently mainstream. The Cache capacity is 8 K or less, which is usually 16 K, and 32 K or more is large. The arm9-architecture has a common 920 T/922 T/940T and a reinforced 926E/946E/966E. MIPS is divided into 2 K, 3 K, 4 K, and 5 K. The performance and structure of different models vary greatly.

When it comes to PC games, first you need to choose a suitable computer host to get a good game effect. Of course, as much as possible to control the cost of the purchase will be the original intention of each user, but game enthusiasts know that if you want to truly experience the smooth and beautiful picture, you need a powerful PC to achieve. Most of the time, desktop PCs are a good choice because they have more performance in the same budget. However, the mobility of desktop PCs is a problem
