~ Procurement comes to mind ~

Last week, Tang handed me the case for this purchase, and I bought four simulators and completed the model. I am buying some chips, 376, arm, PowerPC, and I just want to buy one. Okay, let's deal with such a small thing. You can go on a business trip. I had three hot pots over the weekend and caught a cold. I couldn't do anything for the first two days. I'm in a hurry. I want to deliver the goods this week !!!

After two days of busy work, I made countless phone calls and sent n emails. Finally, I came up with some eyebrows. XQ is still there for dinner this afternoon. I called and sent an email, sitting there, obviously feeling the pressure of my heart. I couldn't stand it for a while. I quickly stood up and went to the toilet to check whether someone else was playing the table tennis. I started to look at it right and right before I started again. I don't want to get tired when I am in hospital.

In fact, it seems very simple, but it is actually very important. For example, although the purchase simulator was prepared by Tang, I thought it over again. Low-end chips are likely to be an important application direction in the future, because we have not considered many chips. In order to take this aspect into consideration, the procurement scheme has been adjusted many times.

No such product is generic and applicable to high-end products. The low-end products are not easy to use. The low-end products are good and there is no way to apply high-end products. Both the high-end and the bottom-end are required, and the versatility may be much worse. In addition, different systems require different software, and you also need to pay for it. So there seems to be a perfect solution, and there is still a problem in the end.

I also don't know about chips. To know the model of a chip in time, you also need to find all the subfix and suffix of the chip. What encapsulation method, temperature level, with no flash, and no can problems. What is arm. Arm is also divided into 7, 9, and 11. Some companies also offer arm and DSP dual-core chips. After understanding arm, I had to go to the relevant chips and asked them everywhere. Google to Google. However, we still need to increase a lot of knowledge. Although ColdFire and Dragonball have no chance to understand them, it is helpful to know something. Ms chips are getting faster and more integrated. But this is not today's flash, and tomorrow it will be 1 mflash. Or today's 20 MHz, and tomorrow's 200 MHz. It is obvious that the chip products are progressive.

In this technology era, how to use existing products is very important. Taking chips as an example, it is critical for you to choose the chips you want to develop. Chip selection, including software development, hardware development, basic development, application objects, and costs, can all be well considered. In other words, this is a product era. The most important application of parts is to products. If your component selection is poor, it may adversely affect the performance and cost of the product. In the end, the product may fail.

In the technology age, the technical mastery of parts directly reflects the industrial level. For example, can a chip be made by itself? Can an engine build a horse on its own? For the automobile industry, the profit of the entire vehicle has been gradually transferred to parts. The components are moved to some more basic components, such as chips and sensors. The lower the profit transfer, the higher the industrial level.

Miss Yun 10 again. Although China does not have its own engine, it is still working hard in addition to rockets, airplanes, and cars. However, it makes no sense to say anything without the ten products. At least it proves that our industry level and product profit have not reached any stage. Some people are not far-sighted to say that they should not be able to mount the game without an engine.
