1 Introduction to Xilinx FFT IP The Xilinx Fast Fourier Transform (FFT IP) core implements the Cooley-Tukey FFT algorithm, which is an efficient method for computing the Discrete Fourier Transform (DFT). 1) Forward and inverse complex FFT, with configurable runtime. 2) Transform size N = 2m, m = 3 – 16 3) Data sampling precision … Read more
First, let’s clarify what is meant by “timing” here, which refers to the logical relationships of a set of signals, rather than timing parameters like steptime and holdtime. If you want to understand why this article exists, please refer to the series “Where is FPGA Going” and “What HLS Does FPGA Need”. Here, we focus … Read more
Once you understand the memory access path, you might wonder: what exactly are the read and write requests sent out by the processor? To clarify this, we need to introduce the bus. Below, I will discuss the ARM’s AXI/ACE bus protocols and the bus structures derived from them. These two protocols are widely used in … Read more
Although the AXI interface is frequently used, many may not be aware that Vivado also integrates AXI Verification IP, which can serve as an AXI master, pass-through, and slave. In this content, we will explore how to use the AXI VIP as a master. Create a new Vivado project and a new block design named: … Read more
