This is a series of projects for the System Programmig course in the Department of Computer Science and Engineering at Sogang University, Seoul, South Korea.
The result is an implementation of SIC/XE Machine with features such as shell environment, assembler and linking loader.
- Allocated virtual memory: 1 MB
- [ OK ] Shell environment
- [ OK ] Assembler (pass1, pass2)
- [ OK ] Modification record (Relocation)
- [ OK ] Linking loader (pass1, pass2)
- [ OK ] Basic execution
- h[elp] : show list and format of commands.
- d[ir] : show list of entries in current directory.
- q[uit] : exit system.
- hi[story] : show list of valid commands entered during current session.
- du[mp] [start, end] : print content of virtual memory.
- e[dit] address, value : change value at designated memory address.
- f[ill] start, end, value : batch fill an interval in address with a value.
- reset : set whole memory to 0x00.
- opcode mnemonic : lookup for the code of the opcode mnemonic.
- opcodelist : show opcode list stored in hash table.
