!) Tutorial. Without saying anything, read this article, and you can "inadvertently" sell debug in your predecessors or later generations. It's a great sense of accomplishment. Try it! So what about next? -Here we go! (It doesn't matter if you don't understand it when you read it. It must be broken down in the following sections.) Because assembly is used to communicate with hardware through CPU and memory, so we have to first understand the CPU and memory: (this is not to mention the number of
digits that the CPU can process at a time.
32-bit: The 32-bit computer's CPU can process up to 32-bit data at a time
64-bit: that is, the processor can run 64-bit data at a time.
CPU level (i386, i586, i686, x86_64)
This is widely used in Linux. This is not the case in windows.
The CPU in Intel Pentium MMX and AMD K6 is called i586, while the 32-bit CPU after intel celon and AMD athlon (K7) is called i68
Hyperthreading technology and parallel computing Analysis in H.264 Encoder
[Author: Wang Yu, Lin Tao, Tongji University]
H.264 is a new generation of video compression standard jointly developed by ITU-T and ISO. Compared with the previous standards, the computing accuracy and some specific algorithms are greatly improved. These improvements enable H.264 to provide higher compression ratios and lower bit rates. However, we should see that the performance imp
