AN ADVERTICING MODUL, DEVELOPED ON THE BASE OF A CPLD PROGRAMABLE DEVICE
Иван Симеонов · 2004
A design of an advertising module, developed on the base of a chosen typical contemporary structure of a reprogrammable CPLD device from the series XC9500, a produce of the firm Xilinx, is presented in the paper. The choice had been made according to the following circumstances: easy accessibility of the devices from this type, low cost, a comfortable programmer assurance for programming and reprogramming, offered freely by the Internet from the firm developer. For the development of the project an integrated system WebPack (ver 6.2) of the firm Xilinx is used. For the realization of the idea a VHDL description of the block scheme of the designed advertising module is used. The CPLD device is configured in laboratory conditions “in system programmable”. The programming of the scheme is being made according to the standard IEEE 1149.1 JTAG, by means of a specialized programmer CPLD XC95XL Design Board, connected through JTAG (Joint Test Action Group) cable for communication to the parallel port of the personal computer. 1.
