DIY computers have always been a favorite computer enthusiasts, computer assembly usually includes the choice of computer hardware, DIY hardware assembly and operating system installation three parts. For computer enthusiasts, through DIY assembly of their own computers, not only can a deeper understanding of the hardware, understanding the internal structure of computer mainframe, but also to learn to install systems and other knowledge, which can bring a lot of fun. 2015 computer-

corresponding basic data type) Integer i = new integer (XXX) and integer i =xxx; the difference between these two ways:1 The first method does not trigger the process of automatic boxing, and the second method triggers;2 The difference between the efficiency of execution and the utilization of resources. The execution efficiency and resource footprint of the second approach are better than the first case in general (note that this is not absolute). 3, the source problem, interview questions: (r

ARM instruction Set 2The ARM microprocessor supports load/store instructions for transferring data between registers and memory, which is used to transfer data from memory to registers and the storage instruction to do the opposite.LDR instruction (different from MOV, MOV can only operate universal Register)The LDR instruction format is:ldr{conditions} Destination register,The LDR directive is used to transfer a 32-bit word data from memory to the des

, and it has been used in many computer-science textbooks. Intel's engineer, Tede Hoff, invented the world's first microprocessor-4004, a 4-bit microprocessor that only has 45 instructions and can execute only 50,000 instructions per second. Not even the world's first computer ENIAC, developed by the U.S. Army, the University of Pennsylvania, in 1946.But its integration is much higher, a 4004 of the weight

We are at the point in the area of multithreaded microprocessor ubuntures where further progress will require the development of a hardware prototype. this prototype shocould support more than two parallel threads and thread-level speculation (TLS ). currently, no required cial Microprocessor has these multithreading capabilities and this prevents the serious OS, compiler and application development that is

1.1.1 software platform Selection 1. Operating System Selection Although the embedded system has a very broad market demand and development prospects, the development of embedded systems has experienced twists and turns and pains for many years. With the advent of microprocessor, low-cost and small-sized CPU and peripheral connections provide a stable and reliable hardware architecture, the bottleneck restricting the development of embedded systems is

Intel Core i7-7700k Contrast i7-6700k which is better? Intel Kabylake and 200 series simply say As mentioned above, the 200 series chip group from B250, H270 to Z270, its wafer PCIe channel number increased, providing more bandwidth increase use, so you can see at least one PCIe X4 storage device, and the other memory frequency from 2400MHz, performance will be improved, Another high-profile Intel Optane memory needs to use the H270 and Z270 motherboard, but the product is not yet on the marke

For student friends, laptops may be an ideal choice for computers because they are powerful and easy to carry. However, if you want to get a more comfortable display, full-sized keyboard and mouse, and speaker experience, an all-in-one computer may be a better choice. Compared to traditional desktops, they are designed to be more concise and flexible, and to support touch-screen operations to achieve a more convenient experience. In addition, the price of the lower also allows you to easily have

bloated, as long as the methods in the interface appear, no matter whether they are useful to the classes dependent on it, these methods must be implemented in the implementation class, which is obviously not a good design. If you change this design to conform to the interface isolation principle, you must split interface I. Here we split the original interface I into three interfaces. The design 2 after the split is shown as follows: (Figure 2 Design following the interface isolation p
