Zynq-7000系列SoC,集成了ARM处理器的软件可编程性和FPGA的硬件可编程性,在单芯片上集成了CPU、DSP、ASSP以及混合信号功能,所以称之为FPGA或ARM处理器都是不准确的。 ZYNQ可分为Zynq-7000、Zynq-7000S和Zynq UltraScale+ MPSoC三大系列。 Zynq-7000系列配置的是28nm Artix-7架构的FPGA和单核ARM Cortex-A9处理器,...
Solution This is a known issue in the 2019.1 OpenAMP release and will be fixed in the 2019.2 release. To work around this issue apply the attached patch to libmetal source using the below steps. 1) Create the libmetal directory in the meta-user layer as follows: mkdir -p /project-spec/m...

在 PS 侧的 APU 上执行通行、规划以及定位算法,PS 侧的 RPU 主要运行底层控制和安全逻辑程序,APU 和 RPU 之间通过 OpenAMP 的框架进行通信和数据交互;在PL 侧通过 FPGA 扩展更多灵活接口以及自主研发的 HiPU 神经网络加速 IP 对目标检测以及深度补全等算法进行加速,最终在一颗 Zynq MPSoC ZU3 有限资源上完成 ...
在ZYNQ中实现双ARM核AMP应用可以参考Xilinx官方的XAPP1078和XAPP1079。在SDK中也有用于双核应用开发的openamp库可以使用。 本例程未使用openamp库,通过自行设计的代码实现了一个简单的双核应用,旨在说明: 双核通过软件中断进行核间通信的原理及方法。 双核通过共享内存进行数据交互的基本原理和设计方法。
如需修改CPU1程序(OpenAMP-remote app)内存地址空间范围，可通过更改设备树文件tlz7x-easyevm-s.dts、...
ZYNQ中存在两个独立的ARM核,在很多应用场景中往往只需使用其中的1个核心即可。然而,对于复杂的设计,例如多任务,并行控制、处理等,单个核心将难以胜任。因此,为了尽可能发挥ZYNQ中双ARM核的优势和性能,进行双核应用的开发显得尤为重要。同时,也进一步为Xilinx下一代MPSOC多核异构处理器的使用打下基础。
