Zynq All Programmable SoC Accelerators
Custom processor accelerators are quickly becoming standard practice for reaching system performance goals. This one-day introduction to the accelerator development flow focuses on how to measure system performance, determine what software functionality should be moved to hardware, how to assemble a custom accelerator using the Vivado® HLS tool, add the custom accelerator to a Zynq® All Programmable SoC design, and finally measure accelerated performance.
Emphasis is placed on the Zynq AP SoC's architectural features that make coupling an accelerator to the multi-processor core a possibility as well as the many techniques for implementing accelerated systems. Discussion of typical tradeoffs that a system architect will likely make is also included. The specifics of the accelerator itself is secondary as the focus is on how to integrate an accelerator rather than accelerator design techniques.

- Lab 1: Impact of Port Selection on System Performance – The Zynq AP SoC has a number of ports. Connecting the accelerator to the wrong one could significantly hamper system performance. This lab explores the balance between loading the AXI ports and processor performance.
- Lab 2: Measuring Performance and Profiling – Here you will learn how to measure system performance and determine through profiling which software functions should be moved to hardware in the form of an accelerator.
- Lab 3: Building a Hardware Accelerator Using the Vivado HLS Tool – The Vivado HLS tool is a powerful C/C++ to netlist building tool that greatly facilitates converting software functions to hardware accelerators.
- Lab 4: Building an Accelerated Embedded System (Accelerator Model) – This lab explores how the accelerator can be attached to the PS.
- Lab 5: Measuring Accelerated System Performance – Having completed a full build of the accelerated embedded system, you will now confirm proper behavior and overall system performance.
