Vitis/Vivado HLS further optimization. I have constructed an adder tree in HLS for incorporating maximum concurrency. The input and weight ports must have a m_axi interface. For my current solution, I have unrolled the multiplication loop by a factor of 8. **Following is my HLS code -. Title. 55279 - Vivado HLS Coding Examples: Implement a simple parallel read/ write mechanism in Vivado HLS. Description. In the example code below, a simple parallel read/write mechanism is being implemented. The purpose of this test module is to check how the code is capable of reading/writing in every clock cycle.

Now we will see how to use a high-level synthesis language to create our own. The tool we will use is called Vitis HLS, henceforth HLS (High-Level Synthesis). HLS takes C and.

the Vitis platform, along with a description of the Himeno benchmark. What follows is an exploration of the workflow required when building and running code using the Vitis platform.

Below is simple implementation of a two-layer MLP that satisfies the static constraints for writing HLS code that can be optimized but has the practical coding style flaws as previously.

Vitis HLS allows the user to easily create complex FPGA-based algorithms using C/C++ code. It supports complex data types (floating-points, fixed-points,) and math functions (sine, arctan, sqrt,). It also supports AXI4-Stream to easily exchange data with other IPs. To find all FPGA-related notes, you can visit FPGA development homepage.

If your original Vitis HLS code uses the dataflow-in-a-loop style, you may push the loop into the tasks. In the following Vitis HLS example, the dataflow region is defined within a loop to be executed for multiple iterations. However, this is not allowed in TAPA, because the loop will become additional logic that may mess up with the computing.
