This article mainly introduces how to use Python to compile a program that imitates CPU work, including the implementation of simple memory and input and output. the example in this article requires a certain degree of Python Programming basics, it is an in-depth Python practice. For more information, see the following interesting article "developing CARDIAC" in my Planet Python source earlier this morning:
Programming of CPU AssemblyIt is the instruction system that reflects the CPU function, and the instruction system is not well designed, it is usually reflected in the program written with these instructions. If more problems can be handled with a program written by a CPU in
I have seen windbg + SOS knowledge for a long time and have never studied it carefully. Maybe the system I have built is not complex enough and I have no permission to view it in the real online environment, I have never learned this knowledge. I have carefully searched for this information in recent days and wrote a test web page that may result in high CPU and high memory, even if you have a chance, you can use a tool to guess what went wrong. Of co
We should be clear, according to their own idea of the design of the CPU is just a hardware, really let the CPU can move to complete the task, it depends on the software. The so-called Software is a program written by the instruction system, of course, including the program operation of the data object. We know that th
How do you want to count the number of packets per second that a server program can handle? The answer is to use the total number of packets processed, divided by the time it takes to process the packets. To point out here, the running of a program, the use of CPU time, and the actual running time is not the same. The bylaws are as follows:

If you know want 50% core utilization, the your algorithm should sleep approximately 0.5 seconds-potentially distrib Uted within a second (e.g. 0.25 sec computation, 0.25 sec sleep, e.t.c.).In addition, the CPU usag
the built-in game, there is already the initial step of a working compiler. I also choose cardiac as a verification machine because it is absolutely simple. No need for complex memories, Each opcode accepts only a single parameter, so it's a great learning tool. In addition, all data parameters are the same, no need to detect a program is a register, string or memory address. In fact, there is only one register, accumulator. So let's get started! We
C # program, how to effectively reduce CPU usage,
Recently developed projects use a third-party program ffmpeg that consumes CPU resources to process videos. So I found out how to solve this problem on the Internet.
Therefore, we can draw a conclusion that to reduce the CPU
Simple Assembly Instruction DesignA computer instruction written in a text symbol is an assembly instruction. What format does this assembly instruction follow in order to correspond to the machine instruction one by one we are designing? As a CPU designer in the design of the command system, it is necessary to consider this aspect of the problem. Consider the format of the machine instruction, and then consider how the assembly instruction correspond

How to end a program that consumes the most CPU resources
Right-click the taskbar and select the Task Manager menu from the shortcut menu that pops up.
Click the "Process" tab in the pop-up Task manager interface as shown in the following figure Red arrow.
Double-click the "CPU" column header as shown in the following figure Red arrow.

This article mainly introduces 10 methods for detecting Python program running time, CPU usage, and memory usage, including using the Python decorator or external UnixShell commands, for more information about how to run complex Python programs, it may take a long time. in this case, you may want to improve the program execution efficiency. But what should we do?

Based on this information, you can basically determine that there is a problem with the program code, there may be unreasonable creation of the o

I have seen a book named "the beauty of programming" in recent days. I want to share my knowledge with you here. If you have better suggestions and solutions, please give me more advice.
