Introduction to Vitis Hardware Acceleration

Tutorial Description
Introduction to Vitis Hardware Acceleration This tutorial provides you with an easy-to-follow, guided introduction to accelerating applications with Xilinx technology. We will begin from the first principles of acceleration: understanding the fundamental architectural approaches, identifying suitable code for acceleration, and interacting with the software APIs for managing memory and interacting with the target device in an optimal way.

Design Tutorials

The methodology for developing optimized accelerated applications is comprised of two major phases: architecting the application, and developing the hardware kernels. In the first phase, you make key decisions about the application architecture by determining which software functions should be accelerated onto FPGA kernels, how much parallelism can be achieved, and how to deliver it in code. In the second phase, you implement the kernels by structuring the source code, and applying the necessary compiler options and pragmas to create the kernel architecture needed to achieve the optimized performance target. The following examples illustrate the use of this methodology in real-world applications.
