Parity Bit Generator

Basic Blocks and Functions

Parity Bit Generators are used to check the integrity of a signal; it is the simplest implementation of a Cyclic Redundancy Check (CRC). Parity Bits are used prior to committing data to an MCU or other control unit to ensure the incoming data hasn’t been corrupted.

Ingredients

Any GreenPAK
No other components are needed

Design Steps

Connect input pins using XOR gates usingTechnique: Configuring Standard Logic w/ LUT Macrocells. XOR gates can be used to calculate the running sum of 1’s.
Add logic for the ENABLE signal.
