Sirc
Sirc (single register computer) as in name it only has a single register, also it doesnt allow any immediate values
Architecture
- The CPU has a single register (acc).
- RAM stores both the program and data.
- No immediate values are allowed; all operations depend on values in `acc` or RAM.
- Programs begin execution at RAM address `0`.
Memory
- RAM contains both instructions and data.
- RAM is limited to 65536 adresses
- Each RAM adress can hold 2^16 (unsigned)
Instruction Set
Sirc has a minimal set of instructions,
- `hlt` halts the program
- `lac` load given ram adress into acc
- `sac` load acc into given ram adress
- `jgz` jmp to given adress or label (in assembler) if acc > 0
- `jez` jmp to given adress or label (in assembler) if acc == 0
- `jmp` jmp to given adress or label (in assembler) no condition
- `add` adds given ram adress value into acc
- `sub` subtract given ram adress value from acc
Example Programs
Increment a acc
This program increments the value of acc.
lac 0x01 ; load ram adress 0x01 value into acc (this does nothing other than setting ram adress 0x01 value to 1) add 0x01 ; 0x01 is now 1 so we add it into acc
implementations
sadly there is no implementation right now but i am developing in python
