Register Machine Environment
Clone the repository, run cargo build --release and launch main executable.
In theory, there are infinite amount of registers that can store some integer values and integers belong to the interval
of (0, +infinity). Of course, the interpreter use finite set of registers and a program listing cannot contain
integers bigger than usize (64 bits on modern platforms), so there cannot be more than usize registers and the
program cannot operate with numbers bigger than this.
I guess it should enough for education purposes, don't think that somebody will use it for something complicated seriously because of its inefficiency.
Types of instructions:
| Instruction | Meaning |
|---|---|
| Z(n) | zeroing of n-th register value |
| I(n) | increasing by 1 n-th register value |
| T(n,m) | copying n-th register value to m-th register |
| J(n,m,l) | if n == m then jump to l line else next line after the instruction |
This instruction set is similar to sets from Counter machine and Random-access machines.
Enumeration of instruction lines starts from 1.
Let N is amount of instructions in the program. A program finishes if current number of instruction is bigger than N
.
