Get your understanding about parity bits andĮvery closed eye is sleeping, and every open eye.

Read the lab sheet twice before starting the lab.

To change ROM contents use INIT attribute by.

In Hardware Debugger but should bypass the 216

Want to observe cycle-by-cycle, use Apply button.

Xchecker cable clock runs at 1Mhz makes itĭifficult to observe whats going on.

Galois fields knowledge is useless for the lab!.

The last 8 bits of the ROM are set to 0 and are.DONE state Can leave this state only thru RESET.Signal from comparator(if MODE0) and enters DONE Waits until either TC from counter or PARLED.ACTIVE state upon RESET, enables the counter and.3 inputs TC output of counter, comparator and.Want Extra Credit! Do this logic as pre-lab.Use MODE0 operation to find position of error.Use MODE1 operation to detect the error.Introduce only one error in the ROM modify ROM.Enter parity bits on the switches, run MODE1 and.Run MODE1 with all DIP switches set to 0.

If output is 0 then no errors in message.Final counter will be displayed in LEDs (position.Process sequence until pattern in DIP switch is.This is for computing the N parity bits of the.Note The Last N(5) bits of the serial input.The final bits in the flip flops are the parity.Plug in the actual bits serially(one after.Magic!!! You have a 5-bit LFSR in front of you.take an XOR of Bit4 and Bit1 and feed it to Bit2.To FF(K) as input (FF numbered from 0 to N-1) XOR of outputs of FF(N-1) and FF(K-1) and feed it For every term xK in the polynomial compute an.For an N-bit LFSR look at the table in for.Place a linear array of D Flip Flops and feedback.Random Number Generator for collision back-off.An N-bit LFSR counts through all non-zero bit.Things that appear hard are normally trivial, If
