022. Modern Graphics Cards, Part III I originally intended this section mainly to explain the difference between a fixed-function pipeline and a programmable pipeline. There are many experts on Zhihu, so I will borrow the diagrams from this answer: What advantages does a programmable rendering pipeline have over a fixed-function pipeline? What are its applications?... » read more

021. The Modern GPU (Part 2) T&L As mentioned in the previous section, the primary role of a GPU is to turn a 3D scene into a 2D image. Before GPUs existed, this work was done either by a camera or by the human eye. The main subject involved here is geometry. The main problems... » read more

020. The Modern GPU (Part 1) I had actually finished this article, but a problem with Zhihu’s draft system caused the entire saved draft to be lost. So I have decided that from now on, I will always write articles on GitBook first and then copy them to Zhihu. I would also like to explain... » read more

018. A Brief History of Graphics Cards — Part Two According to the plan, this section was supposed to cover VESA, but I felt MDA/CGA still had a lot of interesting ground to cover, so I decided to walk through some of the fun tricks people pulled off under MDA/CGA modes with everyone. The previous... » read more

017. A Look Back at the History of Graphics Cards — Part 1 Recently I studied the history of graphics cards, following the x86 thread as the backbone. Here is a rough summary. The evolution of graphics cards can be divided into the following stages, which are also the major display modes: Text mode Color... » read more

8th-Generation x86 Microarchitecture: Intel Core The Core microarchitecture is a processor internal architecture designed from scratch, but it has a design similar to Pentium M. It has a 14-stage pipeline（Pipeline）, which is more than half shorter than the 31-stage Prescott of the NetBurst architecture. In addition, its execution core also increased from the 3 instructions... » read more

7th-Generation x86 Processor: Pentium 4 The Pentium II and Pentium III that followed the Pentium Pro were both based on the P6 architecture. They introduced no major functional or architectural improvements; instead, the fabrication process continued to advance and clock frequencies continued to rise, with the Pentium III eventually reaching a maximum of 1.4 GHz.... » read more

80686-Pentium Pro SMP Symmetric Multiprocessing The Pentium Pro introduced support for SMP, allowing multiple CPUs to be used in a single machine. There are two primary ways to implement a multiprocessor system. One is called SMP, or symmetric multiprocessing, and the other is NUMA, or Non-Uniform Memory Access. In an SMP system, multiple CPUs have... » read more

80586—Superscalar Execution in the First-Generation Pentium The first-generation Pentium was a fifth-generation microprocessor based on the macro-core x86 architecture, and it began shipping on March 22, 1993. It was the successor to the 486 product line. Pentium was originally supposed to be named 80586 or i586, but was later named “Pentium” (i586 is generally considered... » read more

Slight Improvements to the 80486 The 80286 added segmented memory management and protected mode. The 80386 added paged memory management. These both had an enormous influence on modern operating systems. Because after the improvements in the 386, no more changes of such magnitude took place — the 80386 became a timeless classic. So much so... » read more
