Crate procem 

procem provides a Processor structure, which emulates a real-world processor architecture.

The design is loosely based on the ARM architecture.

The processor operates by loading and executing an assembly Program. A Program is a collection of assembly instructions that the processor iterates over and executes. The instruction set in use must implement the Instruction trait. A default instruction set is available in the procem_default crate.

The Registers and Stack use Word as their data type.

The processor’s Registers, Flags and Stack are directly accessible and modifiable through the Processor structure.

let r0 = processor.registers.get_reg(Register::R0);
processor.registers.set_reg(Register::R1, r0);

let overflow = processor.registers.get_flag(Flag::V);

processor.stack.write(processor.registers.get_reg(Register::SP), 10.into());
let val = processor.stack.read(processor.registers.get_reg(Register::SP));
assert_eq!(val, 10.into());
