Zynq-7000 AP SoC Spectrum Analyzer part 6 - AMS - XADC Signal Acquisition and DMA to L2 Cache & Compete Design Tech Tip

In Tech Tip "Zynq Adding Hardware FFT Tech Tip" the FFT application developed in "Zynq Building an FFT Application Tech Tip" was enhanced by the addition of a hardware FFT implemented in the PL fabric of the Zynq-7000 AP SoC. This enabled us to compare execution times for the ARM processor, NEON SIMD engine and a pure hardware block, all computing the same FFT. The FFT application operates from data in an input table. Previously that data table was loaded with software generated data. In this Tech Tip, hardware will be added to the application to capture data from the on-chip Analog to Digital converter; the XADC block connected to an AMS 101 or other appropriate analog input board.

This Tech Tip will illustrate the use of multiple DMA blocks and how the AXI interconnect can be used to funnel multiple processes into the ACP port of the PS. DMA operations are used for both moving the conve
