BBvm

BBvm is a simple easy virtual machine that run bbin compile from bbasm which is a simple assembly too.

Features

BBvm has a lot built-in system invoke with a default screen enabled device.

• Graphic draw
• Image load
• File read/write
• String op

BB虚拟机

BBvm 是一个简单的虚拟机,其汇编码为 BBasm.

主要功能

BBvm 包含了大量的内建系统调用,并且运行于一个有屏幕的设备上.

• 图形操作
• 图像操作
• 文件操作
• 字符串操作

BBasic

BBasic 是一种掌上学习机的编程平台.BBK BBASIC,简称BB,最早由通宵虫于2006年开发,是由VMBASIC结合QuickBASIC开发而成. 运行于早期步步高学习机平台.

该项目为原步步高 BBasic 虚拟机的一个仿照实现.并在原来的基础上进行了扩展.

• 做到和 BBasic 的汇编码兼容
• 做到和 BBasic 的二进制兼容
• 实现编译 Vasm 的编译器
• 实现 BB 的虚拟机,包括图形界面等所有功能
• 对 BBAsm 进行扩展

参考

• BBAsm 语法参考这里
• BB 虚拟机规范参考这里

bbvm's Issues

Change maven to gradle

Easier to

• generate application.
• add new features.

Implement File base file system invoke.

Implement swing based image codec.

Implement swing based user input system invoke.

Implement all device independent system invoke.

Implement swing based graph system invoke.

Swing graph support key color.
