, this is the pipeline technology. The intel 486 processor has a six-level assembly line and their execution components are as follows:
1. Bus Interface Unit: access register and provide input/output.
2. Code prefetch unit: receives machine commands from Biu and inserts them into a storage area called a command queue.
3. instruction decode unit: decodes the commands in the prefetch queue and translates them into micro-code.
4. Execution Unit: The microcode generated by the execution command deco
Typical Pentium software delay loops can be written using mov and loop instructions.For example, the following instruction sequence can be used for a delay loop: mov CX, countdelay: loop delayThe initial loop counter value of "Count" can be calculated using the cycles required to execute the following Pentium instructions: mov REG/Imm (1 cycle) loop label (5/6 cycles)Note that the Pentium loop instruction r

It has been a while since the chest size reached the C cup, and there are no signs of rebound at all, even the guests looked at me differently. I can have today, but I really want to thank Yi zijia. In fact, my chest was still developing very well at the beginning, but I felt embarrassed when I was in adolescence, so I always wore tight underwear, when I realized the importance of my chest, the tragedy had led to my c
that charm. In this way, I feel very inferior. I decided to change myself. I made an amazing decision, that is, breast enhancement.Yizhijiafeng chest can allow the chest to develop independently. It is rich in skin-promoting factors and achieves the secondary development of the chest. I am thrilled to see these products, they just got three cycles back on their official website. I insisted on using it. At the beginning of the week, there was basicall
modifies a global variable, it may impede Compiler optimization.Code optimization:
1. Eliminate cycle inefficiency: Code moving;2. Reduce process calls;3. eliminate unnecessary memory references: use local variables (stored in registers) to save intermediate results.Superscalar: multiple operations can be performed in an out-of-order manner in each clock cycle, which means that the order of command execution can be different from the order in the machine-level program.4. Loop expansion: reduces
Abstract: The current CPU multiplication is very fast (about one CPU cycle, or two or three cycles are required, but each cycle can start a new multiplication command ), however, Division as a basic instruction is more than expected. It is a very slow operation, and division between integers and floating points is slow. This article will provide some methods or alternative algorithms for division;
(Note: A lot of data in this article may have differe

By filling a rectangle with slashes (/) and backslashes (), youcan generate nice little mazes. Here is an example:
As you can see, paths in the Maze cannot branch, so the whole maze onlycontains cyclic paths and paths entering somewhere and leavingsomewhere else. we are only interested in the cycles. in our example, there are two of them.

In fact, this statement in the development of DSP and other systems are often used, such as the change of some configurations need to delay a few clock cycles before it can take effect, when the ASM ("RPT #7 | | NOP ") can be a shining debut. Although this function we all know and often use, but the specific details many people do not know, including me. Today, in an exchange group, someone suddenly asked the instructions to go down after the executio
Description
Some people believe that there are three cycles into a person's life, which is the start of the day, he, or she is born. These three cycles are the physical, emotional, and intellectual cycles, and they have periods to lengths, D Ays, respectively. There is one peak in each period of a cycle. At the peak of a cycle, a person performs at the correspon

2.1, Clock cycle: Also known as the oscillation period or the crystal period, defined as the reciprocal of the clock frequency, that is, the inverse of the oscillation frequency of the crystal oscillator, calculated as: T (Time) =1/f (OSC). The clock cycle is the most basic and smallest unit of time in a computer. In a clock cycle, the CP

3. Cycle test
There are 4 different types of loops: simple loops, chain loops, nested loops, and unstructured loops, as shown in Figure 10-4-6.
Graph 10-4-6 Classification of loops
For a simple loop, the test should include the following, where n represents the maximum number of times the loop allows.
(1) 0 cycles: Jump directly from the recycle inlet to the recycle exit.
(2) One cycle: find errors in the cyclic initi
As we all know, the CPU is the brain of the computer, it is responsible for executing the program instructions; Memory is responsible for saving data, including the program's own data. As we all know, memory is much slower than CPU. In fact, 30 years ago, the CPU frequency and memory bus frequency at the same level, access to memory is only a bit slower than accessing the CPU register. Since memory development is limited to technology and cost, it is now necessary to get a single piece of data i
