I installed the TinyOS in the 64-bit version of Ubuntu 12.04LTS, but the final compilation was successful, but all the Java tools were not available. This time I re-installed a 32-bit Ubuntu system.

[Guidance] researchers found that when running software on a single core, ARM chips are more efficient than Intel core chips and are more suitable for applications in high-performance computing systems.
On August 1, Beijing time, according to foreign media reports, researchers from the Barcelona super computing center published a paper saying that smartphone chips

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
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
By dynamically changing the CPU voltage, you can adjust the CPU frequency.
The CPU clock frequency can be changed dynamically by changing the clock multiple.
Some processors with adjustable CPU main frequency clock multiples can switch dynamically between different main frequencies and operating voltages without the need for kernel or user intervention.
Terminology Definition
Policy (Policy): In the system, users can only choose the maximum frequency and lower limit, and whether the desire for
The output frequency of the notebook does need to look at the performance of the video card of the notebook, but the more decision of this refresh frequency is the screen itself, the LCD is mainly divided into two kinds of standard 6 hertz, and the other is the Nvidia 3D display which is required by 120 Hertz screen Support, and need to support the graphics card can be, for 100
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
How to set up a notebook external flat panel monitor? The method steps for setting the details are as follows:
The output frequency of the notebook does need to look at the performance of the video card of the notebook, but the more decision of this refresh frequency is the screen itself, the LCD is mainly divided into two kinds of standard 6 hertz, and the other is the Nvidia 3D display which is required by 120
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

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

Story of the "2" bandThe OPENBTS system has two highlights. One is the wireless transceiver, especially the frequency band processing, the other is the network system, especially the alternative to the traditional base station (BTS), the base station controller (BSC), the Mobile Control Center (MSC), and (HLR/VLR) alternative solutions.Say the frequency bands first, the story starts from 1894. This year, German physicist Heinrich Hertz died. The most

A heartbeat or tick is 1 Hz per second, recorded as 1Hz. The unit name is to commemorate the 1888 discovery of electromagnetic radiation in the German engineer Heinrich-Hertz, electromagnetic radiation directly led to the birth of radio and other wirele
