1 gigahertz processor

Key words: Pentium, processor, single instruction multiple data flow extension instruction, SSE, instruction set Profile: With the release of the Intel Pentium III processor, many new features have been brought to the program designers. With these new features, programmers can create better products for users. Many of the new features of Pentium III and Pentium III Xeon (Xeon processors) enable her to ru

I will upload my new book "self-writing processor" (not published yet). Today is the second article. I try to write it every Thursday. Chapter 2 processors and MIPS It's time! -- Hu Feng 1949 Let's start reading this book with a poetic sentence. Starting from January 1, November 15, 1971, Intel released the world's first single-chip microprocessor, 4004.1.1 simple computer model The computer is very complic

Any mutex Protocol has the following problem: If the lock cannot be obtained, what should we do? There are two options for this. One solution is to let it continue to try. This lock is calledSpin lockThe repeated lock test process is calledRotating or waiting. It is reasonable to select the rotation method when the lock delay is short. However, only rotating in a multi-processor has practical significance. Taslock Code Code highlighting produce

Researchers at the University of California, Davis (University of California, Davis) recently developed a 1000-core processor called "Kilocore", the world's first processor with 1000 cores. Furthermore, these 1000 cores can also be run independently.The Kilocore can execute 1.78 trillion instructions per second, at least in the processor designed by university re

I will upload my new book "self-writing processor" (not published yet). Today is the fifth article. I try to write this article every Thursday. Based on the introduction in the previous chapter, you should know that the CPU has some basic circuits, such as decoding circuit, calculation circuit, control circuit, and some registers. How can these circuits be implemented? Of course, it can be achieved through a lot of discrete components. In fact, in 20

There is a huge opportunity to migrate games and other applications that use a large number of 3D graphics from OpenGL to Google Android devices, including devices built on Intel's atom micro-architecture, because OpenGL-based games, game engines, and other traditional software are easy to obtain, OpenGL is easy to transplant, and Android can provide OpenGL ES and C/C ++ support. Even, the availability of many OpenGL-based games and engines is the same as that of open-source Software, such as th

. Exception Introduction: A problem that indicates that the CPU executes the instruction itself such as arithmetic overflow, clear 0, the number of parity errors, the visit address out of bounds or executed "into the command" and so on, At this point the hardware changes the current execution process of the CPU, goes to the appropriate error handler or exception handler, or executes a system call 6. event Partitioning Interrupt (external interrupt): IO interrupt: Press CTRL + C on the key
