Digital Given Unit Based on Complex Programmable Logic Device

This paper introduces a design scheme, which is a kind of digital given unit based on Complex Programmable Logic Device. According to the oldcircuit, the new system adopts MAX7000 programmable logicdevice family produced byAltera. Manufactured on an advanced CMOS process, based on electrically-erasable programmable read-only memory (EEPROM), offer densities from 600 to 10 000 usable gates with pin-to-pin delays as fast as 3.5 ns. MAX7000 devices support in-system programmability (ISP) and can be easily reconfigured in the field. All these not only economize elements butalso make the designing simple, and meet the requirementofdevelopment of high-integrationdensity circuit.
