1 Introduction
The ZedBoard is an evaluation and development board based on the Xilinx Zynq -7000 All
Programmable SoC (AP SoC). Combining a dual Corex-A9 Processing System (PS) with 85,000
Series-7 Programmable Logic (PL) cells, the Zynq-7000 AP SoC can be targeted for broad use in
many applications. The ZedBoard’s robust mix of on-board peripherals and expansion
capabilities make it an ideal platform for both novice and experienced designers. The features
provided by the ZedBoard consist of:
