fieldbuses are the most common used communication systems in industrial applications. Nowadays there are a lot of incompatible different solutions causing economic waste when little change in bus definitions are carried out. this paper proposes the implementation of reconfigurable fieldbuses using reconfigurable devices like FPGA (fieldprogrammable gate array) or PLD (programmablelogic device). To evaluate the viability of this solution, this work implements the PROFIBUS (Process fieldbus) protocol in an Altera's FPGA to connect a temperature sensor to a PROFIBUS bus. the physical level of the protocol as well as the required services of the data link level have been implemented in the FPGA.

the flexibility of fieldprogrammable gate arrays (FPGAs) can provide arithmetic intensive applications withthe benefites of custom hardware but without the high cost of custom silicon implementations. In this paper present the adaptation of radix 2 division algorithm for lookup table based FPGAs implementation. this division algorithm is well suited for IEEE 754 standard operands belonging to the range. the implementation has been done with xilinx technology and FPGA-Advantage CAD tools.
