Fetch and Increment Cycle

The Fetch and Increment module of the Instruction Decoder generates the following necessary control signals:

  • Fetch the current instruction (based on the current Program Counter) from the SRAM memory into the Instruction Register
  • Increment the Program Counter

The following animation shows how the Fetch- and Increment Cycle is executed physically on the CPU. You can see when and how the various physical modules interact with each other.
