Intel 8080 CPU assembler in Go

This is my Intel 8080 CPU assembler, which I wrote to support my Intel 8080 CPU emulator.

It takes a newline separated string of Intel 8080 instructions, parses and validates the tokens, and then returns the assembled byte code.

Features

• ✅ Tokeniser
• ✅ Parser
• ✅ Comment support
• ✅ Supports full (244) 8080 CPU instructions

TODO

• Label support
• Data support (eg, DB, DW)
• 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"
