Simple 8-bit V8-CPU Simulator with Assembler/C-subset Compiler

V8-CPU simulator is used for labs& exercises on first-year(freshman) undergraduate CS course "An Overview of Computer Science" in Dept. of CS in Tsinghua Univ. This simulator provides a simplified assembler/C syntax and is simulating a simple 8-bit RISC cpu. Press Help inside the simulator to see an overview about the supported instructions, which is based on Appendix C contents in Computer Science: An Overview textbook.

How to build

Make sure you have Grunt installed to compile the asmsimulator.js script.

steps in ubuntu 16.04 x64

sudo apt install npm nodejs-legacy  php7.0-cli
alias cnpm="npm --registry=https://registry.npm.taobao.org \
--cache=$HOME/.npm/.cache/cnpm \
--disturl=https://npm.taobao.org/dist \
--userconfig=$HOME/.cnpmrc"
cd v8-cpu
cnpm install
cnpm grunt-cli
./node_modules/.bin/grunt
cd cucu
make install
cd ..
./node_modules/.bin/grunt http

Run npm install && grunt to build the project and grunt http to run.
