9. Optimizing Your FPGA AI Suite IP
Optimization of the FPGA AI Suite IP generated by the FPGA AI Suite is essential for achieving application-specific performance, latency, and resource utilization targets.
The FPGA AI Suite provides a comprehensive toolchain that integrates model compilation, architecture tuning, and IP generation for deployment on advanced FPGA platforms. A central part of this toolchain is the architecture configuration file (.arch) that defines key parameters such as processing element (PE) array dimensions, data precision (for example, INT8, FP16), memory interface widths, and activation function implementations.
Fine-tuning these parameters in the architecture file enables efficient mapping of neural network workloads to FPGA resources. Additional optimization tactics include layer fusion, operator reordering, and partitioning of heterogeneous graphs to isolate unsupported layers. These techniques, when used in conjunction with the FPGA AI Suite compiler and performance estimation tools, allow for iterative refinement of the architecture to meet throughput, latency, and area constraints across a wide range of AI workloads.
