Strategies for Optimizing FPGA Designs on AMD Versal Adaptive SoCs

In the rapidly advancing domain of FPGA design, optimizing performance and efficiency is crucial for companies seeking to innovate and remain competitive. This blog delves into the essential strategies for optimizing FPGA designs using AMD Versal Adaptive SoCs, focusing on high-speed data transfer, dynamic function exchange (DFX), and quality of service (QoS) implementation. With insights from Fidus Systems’ recent webinar led by Normand Leclerc, a seasoned FPGA Designer, we explore the intricacies of enhancing your FPGA designs to achieve superior performance and efficiency.

Here, engineers and decision-makers will learn not only how to leverage AMD Versal Adaptive SoCs for custom FPGA solutions but also how to implement advanced techniques that bring their high-complexity FPGA designs to life.

Understanding AMD Versal Adaptive SoCs

To address these challenges, AMD Versal Adaptive SoCs include a high-speed network on chip (NoC). The NoC can transfer data at up to one gigahertz on a 128-bit data bus and features integrated high-efficiency DDR4 and LPDDR4 memory controllers. Some models also include HBM memory controllers. The NoC supports bandwidth allocation and multiple levels of quality of service (QoS), ensuring efficient data transfer across the SoC.

High-Speed Data Moving Application Example

Project Configuration

In this example, data is transferred from HDMI transceivers to LPDDR memory using the NoC. The project configuration involves selecting appropriate AXI interfaces, configuring memory controller ports, and setting up QoS to ensure efficient data flow. This approach demonstrates the NoC’s ability to handle high-speed data movement effectively.

Detailed NoC Configuration

Configuring the NoC involves several key steps:

Input and Output Configuration:

• Associating AXI Interfaces: Assign each slave AXI interface to its corresponding peripheral. For example, the first interface may be cache-coherent, while others handle non-coherent and low-power domain interfaces.
• Connecting Masters: Connect the master AXI interfaces to key components like AI engines and the HDMI frame grabber.

Connectivity Matrix:

• Defining Paths: Specify which slave AXI interfaces can access which master interfaces. This ensures data can be routed efficiently to its destination.
• Quality of Service (QoS) Settings: Configure QoS to prioritize critical data transfers. For instance, video data may require isochronous QoS to guarantee timely delivery.

Memory Controller Configuration:

• Setting Base Addresses: Define base addresses for memory controllers to manage data storage.
• Configuring Timings: Set timings for DDR chips and enable ECC memory if necessary.

Implementing Quality of Service (QoS)

Implementing QoS is critical for applications with specific latency and bandwidth requirements. In the high-speed data moving example, isochronous QoS is used for video data to guarantee maximum latency, ensuring timely delivery of video frames. Other types of QoS, such as high priority or best effort, can be configured based on the application’s needs.

Steps to Implement QoS:

• Identify Traffic Types: Categorize traffic based on latency and bandwidth requirements.
• Assign QoS Levels: Apply appropriate QoS levels (e.g., isochronous, high priority) to different traffic types.
• Monitor and Adjust: Continuously monitor QoS performance and make adjustments to optimize data flow.

Detailed QoS Implementation:

Categorize Traffic:

• Identify critical data flows, such as video feeds, that require low latency and high bandwidth.
• Categorize control signals and less critical data separately.

Configure QoS:

• Use the NoC configuration tool to assign QoS levels to each data flow.
• Set isochronous QoS for video feeds to guarantee timely data transfer.

Monitor Performance:

• Use monitoring tools to track QoS performance.
• Adjust settings as needed to ensure optimal data flow and system efficiency.
