[hyperdriveguy]

Documentation

• ISA definition
  • Arithmetic operations
  • Data operations
  • Address operations
  • Branching operations
  • Other operations
• Instruction size
  • This should be a fixed size for simplicity (RISC)
  • Dependent on register file size
• Usability features
  • Macro support
  • Constants/variables
  • Address labels
  • Characters to ASCII or character maps
  • Include ASM
  • Include binary files
  • Origin/alignment directive

Implementation

• Reuse existing Python assembler
• Implement correct ISA
• Remove built-in macros for display
• Make binary export importable (mem file?)

Prerequisites

• 8-bit Register File #3 Register File for number of registers
• ALU #1 Full list of arithmetic operations to be implemented
