MLeM

The Machine Learning Machine is a 64-bit virtual Harvard-arch machine for evolutionary algorithms to program against.

The machine has eight GPRs (R0 through R7), a hardware stack with SP and BP, and hardware I/O with Input and Output.

These I/O instructions write out whole u64s in big endian using byteorder.

Example

This example shows a simple program being executed by the MLeM managed execution routine.

use mlem::{execute, Instruction, Address, Register, Outcome}; let input = vec![2, 2, 2, 2]; let expected = vec![4, 0]; let program = vec![ // Get all input values Instruction::Input(Address::RegAbs(Register::R0)), Instruction::Input(Address::RegAbs(Register::R1)), Instruction::Input(Address::RegAbs(Register::R2)), Instruction::Input(Address::RegAbs(Register::R3)), // Perform arithmetic Instruction::Add(Address::RegAbs(Register::R0), Address::RegAbs(Register::R1)), Instruction::Sub(Address::RegAbs(Register::R2), Address::RegAbs(Register::R3)), // Output computed values Instruction::Output(Address::RegAbs(Register::R0)), Instruction::Output(Address::RegAbs(Register::R2)), // Halt Instruction::Halt ]; //! let (outcome, _, output) = execute(program, input); assert!(outcome == Outcome::Halt, "Program did not successfully halt! {:?}", outcome); assert!(output == expected, "Program did not produce {:?} as expected, but rather {:?}.", expected, output);
