Baremetal RISC-V Renode

http://github.com/y2kbugger/baremetal-riscv-renode
一个教育介绍开发嵌入式C产品使用模拟硬件针对初学者. 我通过在一个极小的空间内创建一系列演示来探索硬件和软件之间的界限, free, open-source environment. 这些演示涵盖了从闪烁LED到实现玩具操作系统的各个部分. 目标是阐明我们认为理所当然的系统部分，并更好地理解计算机和操作系统.

我是代码示例和编译指令的唯一开发者, 以及关于该主题的博客文章和LinuxFest 2020会议演讲. 这降低了新的嵌入式C和ASM开发人员的进入门槛，同时增加了开放硬件标准(如RISC-V)的生态系统.

Conference Talk on How CPUs Work

http://mybinder.org/v2/gh/y2kbugger/sapy.git/mybinder-release
一个关于我自己的微可编程CPU模拟器的会议报告. 目标是教cpu如何在内部工作，以及它们如何与计算机的其余部分接口. 我是唯一一个开发交互式框架的人，这个框架允许单步执行微代码, assembling from a custom assembly language, and performing simple IO. 我也是这个项目的唯一贡献者，我在PyOhio 2019会议上发表了这个项目.

My talk, 《欧博体育app下载》,帮助高级程序员了解低级别的计算机中发生的事情. 在演讲中，我们构建了一个专注于透明性、交互性和模块化的CPU. Our CPU has a configurable architecture and machine language, 而且它是可扩展的，可以使用新的指令来添加功能. 讲座涵盖了寄存器、数据和地址总线、存储器(ROM和RAM)、IO和汇编程序.

A Simple RISC-V Multitasking OS for Learning

http://blog.y2kbugger.com/2021-12-03-ohiolinuxfest.html
通过编写对CPU和外围设备具有绝对控制权的代码，探索硬件和软件之间的界限. 我们将探索如何使用完全免费和开源的模拟器(Renode)来实现这一点。, toolchain (GCC), and instruction set (RISC-V). 使用汇编，我们将初始化系统部件，如CPU中断和特权级别. Finally, we'll review the assembly code for doing a context switch, the key software which enables multitasking via timesharing.
