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.
