Intel 8080 CPU assembler in Go

What good is an 8080 CPU emulator without an assembler?

This project takes an input string, tokenises the string into a slice of tokens, then parses those tokens, converting each to a valid 8080 opcode.

Features

• ✅ Tokeniser
• ✅ Parser
• ✅ Comment support
• ✅ Supports all 244 instructions on the 8080 cpu

TODO

• Label support
• Data support (define byte, word, storage)
• Input from STDIN

Usage

code := `
	MVI A, 34h
	MOV B, C
	LDA 1234h
	HLT
`

assembler := &assembler.Assembler{}
assembler.Assemble(code)
for _, instruction := range assembler.ByteCode {
	fmt.Printf("%02X ", instruction)
}

// Prints "3E 34 41 3A 34 12 76"
