Circuit Design: This is a very big concept, from the voltage intensity can be divided into strong electric circuit design and Weak Current Circuit Design; from the design tool can be divided into manual drawing and electronic auxiliary design, the circuit types can be divided into analog circuit design and digital circuit design. Icdesign: The IC Design refers to the chip design, that is, the design of the circuit on a crystalline silicon chip, whi

Relative humidity measurement using IC SensorsXie Changjiang youlihuaSummary: Based on the comparison of various relative humidity measurement methods and sensors, this paper introduces the characteristics and usage of integrated humidity sensor based on examples, and points out the influencing factors and compensation methods of the conditions, the specific implementation line of relative humidity detection with temperature effect compensation is pro

In the BS structure of the program, how to develop a cross-web browser IC card reader program?In general, the use of physical hardware in a BS structure program has many limitations, and the OCX control that is addressed through ActiveX technology is only available on IE and cannot be used in Chrome or Firefox. Friends of my technology to provide RFID reader cloud services to completely solve this problem, he can not only use in IE, but also in the Ch

Safety | problems | Reading and writing of IC card under the security B/s You need to use ActiveX to assist with the completion, ActiveX is downloaded to each client execution, any user can get the ActiveX. If the security requirements of IC card is very high, in the process of encrypting data or password is difficult to perfect, because the client's ActiveX needs to cooperate with the script such as JS or

Linear Technology ' s recently introduced LTC4300 chip buffers i²c clock and data lines to and from a hot-swappable card. This task was difficult because the IC must work bidirectionally, meaning so can simultaneously and actively drive BO Th sides. However, as is sometimes the case, you can replace a complicated circuit by a simple one without much loss of performance. For example, transistors and resistors replace the entire

protected (solidified), it cannot be changed. Use unique code as the system The ID of the IC card to prevent counterfeit cards of the same model from entering the system. 2. SLE4442 card can read the data of the whole card without a password. Therefore, you should pay attention to content encryption during design to prevent damage. Identify the data format. 3. The whole card is not partitioned. Once the password is checked correctly, data can be writ

technology is also the effect of radio wave communication and electromagnetic. As for the application of embedded on-chip systems, the key lies in the understanding of chips, but it was not clear at the time, but with curiosity and interest. I heard that a company next to the school did a great job in this area, so I volunteered to call the internship in the summer of my junior year. From then on, I was exposed to smart IC cards and mobile payments

North-South Network (core network) is the responsibility of carrying traffic, reliable, safe is the key.

This kind of enterprise only wears "the Internet +" The cloak, does the qishidaoming dream, finally becomes "the Internet-" The model and dies, such example is a plethora of examples ...Any business that does not aim to make money is bullying, but the business cannot be born for money alone.

, in fact, it does not save the memory. I recommend it because of the speed of the operation. In this example, we can see the difference between the unsigned operation and the signed operation on the digital path, that is to say, if only Int Is Used in C/C ++, signed operation will be run in the hardware, and unsigned int will run unsigned operation, which is fast, therefore, the estimation is based on the speed consideration using the unsigned Int.

dominated by Synopsys, and OVM is developed by Cadence and mentor. 6. assert is a good thing. Assert is very powerful and easy to use. It is precisely because of its advantages that it can discover design errors and locate problems accurately, so the verification engineer cannot use it very easily, because the verification engineer generally can verify the design module without having to know too much design details, but assert needs to have a clear understanding of the internal signal, to co

, the relationship is still stuck in the relationship between object Orientation Analysis and Design. After all, the tool will complete the practices of COM + and Web Service. The same is true for SoC Development. with EDA tool, more and more integrated, the more integrated the design IC is, in addition, most of the actual work has been completed by EDA tool. Only analysis and design can be performed by humans. In order to conquer the attention and re
