8-bit assembler compiler project

This project is an assembler compiler to generate a binary executable for 8-bit x86 like CPU systems. This compiler can parse NASM style assembler code and it compatibles with Marco Schweighauser's javascript 8-bit virtual CPU . Compare with Marco Schweighauser's javascript compiler this compiler parse almost same assembler code and generate almost identical executable code. The only difference in this parser is that all the operands are separated by white space(s), and not with the comma ( , ). jmp start hello: db "Hello World!" db 0 start: mov c hello mov d 232 call print hlt print: push a push b mov b 0 loop: mov a [c] mov [d] a inc c inc d cmp b [c] jnz loop pop b pop a ret The output generated by this compiler for " Hello World " sample is listed in below and it can execute directly with Marco Schweighauser's 8-bit virtual CPU . 0000 1F0F 4865 6C6C 6F20 576F 726C 6421 0006 0010 0202 0603 E838 1800 3200 320...

LiteASM - Light Weight & Customizable Assembly Compiler & Virtual Machine

LiteASM is a Light weight and reconfigurable Assembly language compiler and Virtual Machine. It is design to fulfill the following core requirements: As a scripting interface for embedded systems. As a cross platform scripting interface. As a experimental tool for compiler construction. LiteASM compiler is design with minimum static instruction set. Its dynamic instruction set can be easily extend using compilers configuration files. LiteASM compiler generate fixed length binary output file and it can execute on LiteASM Virtual Machine Simulator ( litevm ) or on top of platform specific virtual machine. Virtually LiteASM Virtual Machines can execute on any 8bit to 64bit CPU/MCU/DSP platform. 8bit version of Fibonacci series demo on LiteASM Virtual Machine Simulator LiteASM compiler and Virtual Machine simulator are distribute as a free and open source software (under the terms of GNU GPL version 3.0 ) and available for both Windows and Linux operating systems.
