Do embedded system development, often have to touch the hardware. Do embedded development on the digital circuit and analog circuit to have a certain understanding. So that we can go into deep research. The following is a brief introduction to some of the hardware-related concepts in embedded development.Levels (Level)In digital circuits, it is divided into high and low levels, which are represented by 1 and 0 respectively. The pin of a digital circuit always has a level, either high or low, or
again.
Pseudo code:
FIND-MAXSUB (a) max-sum =-INF sum = 0 low = 1 High = 1 for I = 1 to. length Sum = sum + A [I] If sum> MAX-sum max-sum = sum high = I // If a [low .. i]
C ++ implementation:
Void find_maxsub (int * a, int a_length, maxsubarray * result) {int max_sum =-INF; int sum = 0; int low = 0; int high = 0; for (INT I = 0; I

Large-scale chip testing:Professor Diogenes has n well-considered to be exactly the same IC. In principle, they can be mutually tested. the professor's test device can test two pieces at a time. When two pieces of chips are installed in the device, each piece tests the other and reports its quality. A good chip can always correctly report the quality of another chip, but the result of a bad chip is unreliable. in this way, the four possible results of

The first experiment was Zynga doing Angry Birds game manufacturers, 2010 wrote the demo scroller:

Blue chip stocksIt refers to a listed company with a large share capital and market value, but not all large-disk shares can be called blue-chip stocks. Therefore, it is difficult to set a definite standard for blue-chip stocks. From the experiences of various countries, companies with large market capitalization, stable performance, leading position in the industry and considerable impact on the securities market, such as Hong Kong's changshi and Huang; IBM in the United States, the British Lab
At the Google I/O conference held last week, Google officially announced the second generation of TPU, also known as Cloud TPU or TPU 2. However, Google has not introduced its new chip in detail, showing only a few photos.
The next platform released an article today, based on Google's images and details, takes you to the TPU2 of Google. The quantum bits are compiled as follows:
The first thing to say is that Google is unlikely to sell TPU chips, mothe
What impressed me the most was the chips. In the words of Bai yansong, "in life, the most important thing is to maintain your inreplaceable ". The path here is exactly the same as that of the chips. Only irreplaceable can you express your value. As a result, I think of playing chess. Every piece has its value. Each game is a bargaining chip in your hands. Only by recognizing this, can you not lose your way

As far as Bada shares are concerned, I have always known that the main positions are heavy, but I have not calculated the details. On Friday, I finally reached the pre-high point. I was shocked when I started to calculate it, at present, the main position of Bada shares is more than 65%. In addition, the 20% chips in the general stock are very stable, so th
(Candy Crush Saga) is filtered through this process. Innovation requires experimentation, and when there is always a failure, the way that multiple teams develop quickly makes the cost of failure very low, and after a game fails, there are other games. Its rivals, such as Zynga, will spend more than two years, spending more than 100 people, and investing $10 million to develop Ville series games. This risk is too great for innovation, because once in
At the seminar, the two schemes were completely different. One uses a general chip, such as DSP, arm9-and FPGA, and one uses a dedicated chip, such as a copy, scan, and fax integrated chip. The two solutions have their own advantages and disadvantages:
The general-purpose chip has the following advantages:
1. It is easy to purchase chips. Not only depends on one model. Any MCU can. The nxp arm chip can be used, the Atmel chip can also be used, and the
whether all chips have missing pins and do not connect to X
Do not connect the function pins of the chip to the wrong ones. For example, the audio processing chip I use has three clock pins: lclk, bclk, and mclk, which must correspond to the three audio clock pins of the main chip one by one, A single record cannot work.
Whether there are missing pins is actually very easy to troubleshoot, carefully observe the various
complement each other. Just like a real question: Without Chillingo, can Cut The Rope continuously win The best head game awards on BAFTA and GDC? Or if The success of Cut The Rope and Angry Birds is not achieved, can Chillingo play an important role in The publishing field like it is now?
There is no doubt that users usually associate game products with product release cards, but developers' efforts are easily ignored. Even if publishers try to increase the exposure of developers' names as muc
If you really don't wash my so this time, I decided to contact the party. I confess, I will explain, the following is the whole process of my acquisition of you. At that time, it was Ma Yue in the year of ox, and the international situation was very good. The financial crisis in Southeast Asia has passed the "Ninth Five-Year Plan" of the Asian economy, which is on the right track for healthy development.In such a period of national security, I decided to implement an acquisition plan for you.
Google or Yahoo search is a piece of cake. You just type a word and you'll see a lot of links to this page almost at the same time.
However, the search results usually differ from what you want. If the search term is ambiguous, there will be more unrelated links. If you type "chips", search engines simply don't know if you're looking for a computer chip (computer chips), a potato chip (potato
"865pe motherboard", and 865pe refers to the Motherboard chipset. The Motherboard chipset usually includes both the nanqiao chip and the beiqiao chip, but some motherboard chips also contain one or three chips.
The beiqiao chip mainly determines the motherboard specifications, hardware support, and system performance. It connects to the CPU, memory, and AGP bus. What CPU is supported by the main board, how
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 !!!
