the kernel state, it uses the TSS.SS0, TSS.ESP0, or kernel stack, of the privilege level 0 given in its TSS segment. The original user stack pointer is saved in the kernel stack. When the user state is returned from the kernel state, the stack using the user's state is restored.

In fact, I saw this in LINUX as early as I saw it. Later I also saw something similar in the MFC memory pool. I also wrote a similar small memory pool according to MFC, (MFC uses return this + 1) later, I saw a similar definition in Li xianjing's System Programmer growth plan, So I thought about it as a summary, the results showed that some cool people on the Internet had already summarized it very well, so it turned around.

Problem DescriptionGiven a decimal integer n, the number of "1" occurrences in all integers from 1 to n is calculated. For example: 1 "1" appeared in n=2.n=12 when 1,2,3,4,5,6,7,8,9,10,11,12. There were 5 "1".Method one brute force solutionThe most direct way is to start fro

The two days to learn the timer of the lpc2103. I started to look at the previous register introduction. I felt dizzy and I was confused later. However, when I see the following operations using the image to describe the timer-related registers, it will be clear. After you know the application, you can see the principle again. Why are these two timers put together, because they are both 32-bit timers, which are the same except for the peripheral base address. Let's talk about the features of th

Descriptive narrative of the problemGiven a decimal integer n, the number of "1" appears in all integers from 1 to n.For example: 1 "1" appeared in n=2.n=12 when 1,2,3,4,5,6,7,8,9,10,11,12.There were 5 "1".Thinking of solving problems1-digit situation:In the solution two has

Suppose the backpack capacity m=9; (P1,P2,P3,P4,P5,P6) = (15,18,40,56,30,10);(w1,w2,w3,w4,w,5,w6) = (3,2,5,8,5,1).Algorithmic thinkingVariable Interpretation:F (i): The position of the first pair in the array (subscript) L, the position of the first pair of h:si-1 and the last pair of order pairs in the array, i.e. F (i-1) and F (i)-1.　　The position of the k:si-

maximum value that can be loaded, is still 0, because the item e,d is not the backpack can be installed.In the same vein, c2=0,b2=3,a2=6.For the 8 load-bearing backpack, a8=15, how to draw?According to the state transition equation of 01 knapsack, we need to examine two values,One is f[i-1,j], for this example is the value of B8 9, the other is f[i-

First of all, I would like to thank my brother Xiaoxiao for helping you. Directly give the state transition equation: DP [I] [v] = max (DP [I-1] [v], DP [I-1] [V-Vol [I] + val [I]); Vol [I] is the volume of the I-th item, and Val is the value of the I-th item The equation means that when we consider the I items, there are only two options for I items: Put or not put, if not put the weight is the weight of

0-1 questions about BackpacksKnapsack problem (knapsack Problem) is a np-complete problem of combinatorial Optimization. The problem can be described as: given a set of items, each item has its own weight and price, within a limited total weight, we choose how to make the total price of the item the Highest. The name of the problem comes from how to choose the most suitable item to be placed in a given back
