SIC/XE Machine

CSE4100 System Programming Project / Sogang Univ.

Project 1

Preliminary steps into implement SIC/XE Machine
Shells that will run assemblers, linking loaders
Memory Space that will load and run object code compiled
Opcode table that convert mnemonic (ADD, COMP, FLOAT, etc ...) into opcode values and related commands

• Shell (sicsim> )
• Commands related to Shell (help, dir, quit, history)
• Memory Space (allocated 1MB)
• Commands related to memory space (dump, edit, fill, reset)
• Opcode table (must be made into HashTable)
• Commands related to opcode (opcode, opcodelist)

Project 2

Assemble SIC/XE assembly code file (.asm)
Make object file(.obj) and listing file(.lst)

• Commands related to Shell (help, type)
• Assembler (assemble)
• Commands related to assemble (symbol)

Project 3

Link several object files and load the program on memory.

• Addressing Command (progaddr)
• Linking Loader (loader)
• Run the program (run) $\rightarrow$ need fix
• Debug Command (bp)

---

• compile: make
• run: a.out
• delete: make clean
