So we start from this chapter will enter into Chapter VI bus study, in fact, in the previous chapter which we have more or less had a little contact with the bus, also mentioned some of its concepts, but we were only slightly raised look, and not specifically in terms of expansion. Chapter VI we do come to specifically analyze the bus some of its knowledge. Chapter VI then compared to all the previous sections of the chapter it is relatively simple, because its content is very low, very little knowledge of it.
We look at, among syllabus for bus this chapter, it raised four content. It is the first overview of the bus, the bus and the classification of some of its classic structure, and then to explain the performance of the bus. So this is an overview of some of the bus. The next two sections so that the focus operation with the timing of the bus arbitration and bus. The bus arbitration to solve any kind of problem then it means that there are multiple devices on top of me a bus, but it multiple devices to control the bus, we will use arbitration to resolve such a way so that multiple bus device contention bus The problem. So what we are going to explain the third operation timing of the bus. This section addressed the content of it that is occupied by a pair of devices the bus, how data transmission. Then there is such timing synchronization, and asynchronous timing mode, then the two sections are very important, the two sections. So finally we do a brief introduction about the standard bus, because we know that such a standard is to achieve a modular design. Because there are several different devices say, a plurality of different devices can be connected to such a bus our bus above. So how can they connect, then there must be a standard bus bar. Right, so the fourth quarter we will simply introduce the common bus standards. So everyone said, what the content of this section of this chapter it is relatively small, compared with other chapters, so it compared to other previous chapters, the first five chapters, the sixth Chapter bus is relatively easy. But then it has some knowledge is quite difficult, so we have to be vigilant not be taken lightly.
