arithmetic module
1.In the control system, control signal is achieved mainly by TMS320F2812 digital signal processor , logical process of output signal is implemented by programmable logic CMOS chip GAL20V8. AD sample module , PID arithmetic module , PWM module and dynamic simulation module are designed respectively by C and Compile language.
2.The soft uses the ANSI C, fully utilizes the ActiveX technology, establishes the interface programs among Lab Windows/CVI, matlab and word, and dynamic simulates by driving the module of modeling in the simulink, the arithmetic module of M files in the matlab, and the interface module in the word with C program.
4.To solve the problem of delivering variable inside the template, with the thought of module and based on the geanaeral object technology, this paper, from the ASCII template technique, detailed in analyzing the function and countepart arithmetic of each reference module.
5.In terms of the customerdriven parameter descriptions, parameter mapping and the establishment of encoding regulation on module properties, this paper develops a quantified arithmetic description model that transforms product customization problem into an issue of module assembling optimization.
6.The thesis depicts the designing idea of the concise ADPCM, and describes it in detail with five module, for example, predictor and difference calculation, adaptive quantization and so on, then describes the data structure and coder function of it with C program language, and compares the arithmetic with G.
7.The definition and characters of Double-module quadratic residue is discussed in this paper,The arithmetic for choosing base point of Elliptic curve cryptosystem in optimal extension field is worked out and proven mathematically,moreover,the successful probability is also provided.
8.To illuminate the scheme, the basic operation timing of SDRAM, the DVI interface and the PCI interface are represented. Then the function module of FPGA is introduced. On the point of the specification of Bi-linear interpolation arithmetic, the idea about parallel process in FPGA for quickly random accessing SDRAM is demonstrated.
