serial arithmetic
1.In this testing and controlling system, the sensors of current and voltage signals collecting, insulation and protection of testing and controlling system, mag- nifying of signals,collecting and disposing of signals, serial communication between siglechip and PC computer are narrated. Besides, data disposing arithmetic of calculating current rms is discussed.
2.Two examples, the key modules ALU and serial communication port based on PIC17C42 MCU have been designed. The analysis of function and arithmetic has been researched and the relevant scheme has been designed.
3.By preconditioning an image from a serial of images and based on the traditional differences of images, the authors put forward the connection and filling of moving objects by using math morphologic dilation and erosion arithmetic, and then remove unnecessary point to get moving target.
4.Then some theorys generating safe prime of DH and RSA are given. So we can prove that the prime such that P= 2q + 1 can be get from the arithmetic serial.
