Chapter 4: Getting Started
Lesson 3 Summary
• Use the MCode block for state machines and branch conditional logic
• Use the Expression block to implement logical control at the bit level
• Storage elements have the ability to include optional reset and clock enable pins that
can be connected in System Generator
• Blocks that operate on bursty data include data flow control pins called vin and vout
Lab Exercise: System Control
In this lab you will be creating a simple state machine using the MCode block to detect a
sequence of binary values “1011”. The FSM needs to be able to detect multiple
transmissions as well, i.e., “10111011”
