Efcient Shift Registers, LFSR

Counters, and Long Pseudo-

XAPP 052 July 7,1996 (Version 1.1) Application Note by Peter Alfke


Summary
Shift registers longer than eight bits can be implemented most efciently in XC4000E Select-RAMTM. Using Linear Feedback
Shift-Register (LFSR) counters to address the RAM makes the design even simpler. This application note describes 4- and
5-bit universal LFSR counters, very
