Single Chip Fuzzy Control System Based on Mixed-Signal FPGA

Abstract

A fuzzy control system is analyzed and designed basing on a new hardware platform mixed-signal FPGA. Besides fuzzy control module, FPGA is also embedded with 8051, PWM, ADC. After analyzing the principle of fuzzy control module, it's divided into several modules according to the functional needs on the basis of this division the logic structure of all modules can be obtained. Then based on topdown design method, the fuzzy control module is designed with Verilog HDL, and the whole design is optimized and simulated successfully. Finally, the implementation of the fuzzy control system on a specific FPGA is given.

Research on Multi-Core Collaborative Computing for FWP Image Processing Algorithm by FPGA

“…PowerPC 405 is connected to FCB as main equipment while FCB2FSL is connected to FCB slave equipment. For FSL bus is unidirectional link bus, FCB2FSL is connected to median filtering special processor through two FSL buses(MFSL & SFSL0) [4].…”

“…Liming Wu, etc. (2009) designed multi-processor collaborative working fuzzy control system based on Xilnx Virtex-II and the primary processor of embedded 32-bit soft core MicorBlaze and passed through FSL bus connecting fuzzy inference IP core [3]; document [4] (2009) presented an extensible multi-processor parallel processing method based on multi-level PLB bus, increased processing performance and extended storage and visit bandwidth by adopting bus bridge parallel extended processing unit and realized image data input and processing pipeline operation though data distribution module.…”

Experiment Teaching Case Design for Practice Teaching of Photoelectric Sensor Signal Processing Base on CIS Filtering

“…This paper is the CIS sensor signal acquisition based on FPGA (field programmable gate array) which is a special integrated circuit in one of the highest degree. In order to achieve the logic function which is the user desired, the users can reconfigure the logic module and the I/O module of the FPGA inside [2][3]. The single circuit system with many different circuit functions can meet the requirements of different types of CIS sensor interface and achieve the CIS sensors of different types of plug-and-play expediently, which can improve the compatibility of acquisition module and reduce the cost of hardware development again, so it has application value in the field of CIS image scanning.…”
