Zexium Virtual Machine (aka. ZexVM or ZVM) is a register-based high-level language virtual machine (HLLVM).

Same as JVM, ZexVM is designed to solve the problems about cross-platform. It can run a certain kind of bytecode file, which is platform-independent.

ZexVM has its own instruction set and assembly language (similar to x86), also has an assembler (ZASM). The assembler can convert ZexVM assembly to bytecode file. In the future, there will be a programming language called Arsha can be compiled to ZexVM bytecode.

• Tracing garbage collection while runtime
• String and List type data structure (controlled by garbage collector)
• Function type for a better support of anonymous functions and closures
• 64-bit integer and floating point number
• Call an external function by using INT instruction

There is no appealing feature in the current version (000.006), but we will add a lot of new features in the future, such as:

• Just-In-Time (JIT) compilation or other runtime optimizations
• Class support and OOP
• More advanced functional programming support

This project contains a makefile. Please use make command to build the vitrual machine ZexVM and the assembler ZASM:

make all

Or build one of them:

make zvm
make zasm

Before you build the project, you should make sure that your compiler supported the C++ 14 standard.

To generate a ZexVM bytecode file from the ZexVM assembly, please run:

./zasm <assembly file> [ -o <output file> ]

If there are no errors in the assembly file, ZASM will generate a .zbc file, and then you can run this file by using:

./zvm <zbc file>

For help information, please run command -h or --help.

Please read zvm-is.md.

All of the test cases are in test/ directory.

• hello.zasm: print "Hello world." in command line
• hanoi.zasm: recursively solve the Hanoi Tower problem
• heart.zasm: print a heart pattern
• conv.zasm: test about type conversion
• funcs.zasm functional test about interrupts and GC
