4. Typical Lab Exercises

The XUP program is heavily lab-oriented. A typical course flow includes:

  1. Lab 1: Getting Started: Introduction to the System Generator environment. Blinking an LED (Hello World of hardware).
  2. Lab 2: Fixed-Point Exploration: Comparing a floating-point filter design in MATLAB against a fixed-point implementation in FPGA to observe quantization noise.
  3. Lab 3: FIR Filter Design: Designing a bandpass filter to isolate a specific frequency tone.
  4. Lab 4: Hardware Co-Simulation: Running the filter on the FPGA board and visualizing the output on the PC scope in real-time.
  5. Lab 5 (Project): A small "mini-project" such as an Audio Effects Processor (echo, reverb, or distortion) using the onboard CODEC.

The RFSoC Frontier

For advanced readers, the primer touches on the RFSoC family, which integrates ADCs and DACs running at 4+ GSPS. This is the ultimate DSP-for-FPGA use case: Direct RF sampling without analog mixers.

3.1. Number Systems in DSP FPGAs

The primer begins with fixed-point arithmetic. Unlike floating-point in CPUs, FPGAs excel at custom precision. The primer covers:

  • Binary scaling (Q-format notation, e.g., Q4.12).
  • Quantization effects and truncation versus rounding.
  • Overflow management through saturation logic.

Key takeaway: You learn to trade dynamic range for resource efficiency. Introduction to DSP : The primer begins with

Module 2: Model-Based Design (Simulink & System Generator)

This is often the core of the XUP DSP Primer.

  • Xilinx System Generator Blockset: Learning the specific Xilinx blocks within Simulink (Gateway In/Out, System Generator token).
  • Fixed-Point Arithmetic:
    • Understanding quantization errors and precision.
    • Defining fixed-point types (Signed/Unsigned, Word length, Binary point).
    • Managing overflow and rounding modes.
  • Lab Exercise: Building a simple signal generator or mixer using Simulink blocks and generating the FPGA bitstream.
