Zynq research and development (3) - Zynq core board

Project-based hardware ARM + FPGA, so choose Zynq Soc, ARM processor and FPGA architecture is tightly integrated many convenient than before the separation chip. There may be readily selected Zynq core board, integrated DDR modules, regardless of the design of the core circuit portion. Software, embedded Linux system based on need, to write applications. Project data acquisition and control, a larger storage space. TF card can be configured to start Linux, but consider the needs of anti-vibration, core board chose to take eMMC. TF card can be arranged on the floor. Finally selected Xilinx Zynq-7020 core board is MYC-C7Z020. The following is posted introduction.

MYC-C7Z020 to be a Xilinx Zynq-7020 as the core of embedded core board. Using the new Xilinx based Zynq-7000 All Programmable SoC platform 28nm process, and will be tightly integrated ARM processor and FPGA architectures, PS unit with high-performance dual-core ARM Cortex-A9MPCore, low-power features in the design more good to meet a variety of industrial needs.
