Introduction

The Xilinx® LogiCORE™ IP Audio Formatter core is a soft Xilinx IP core for use with the Xilinx Vivado® Design Suite. The Audio formatter provides high-bandwidth direct memory access between memory and AXI4-Stream target peripherals.

Overview

The Xilinx® LogiCORE™ IP Audio Formatter (Audio DMA) core is a soft Xilinx IP core for use with the Xilinx Vivado® Design Suite. The Audio formatter provides high-bandwidth direct memory access between memory and AXI4-Stream target peripherals. Initialization, status, and management registers are accessed through an AXI4-Lite slave interface. Figure 1-1 illustrates the functional composition of the core.
