Achieving Turing Completeness LMC Branching Achieving Turing Completeness

Turing Completeness Requirements of a "universal" programming language Ability to manipulate symbols (add numbers, do logic) Ability to read/store arbitrary number of values in memory Ability to skip ahead or back in instructions

Branch Branch instructions jump to new location Change PC to XX

Branch Branch instructions jump to new location Change PC to XX

Branch Conditional branch only jumps if Accumulator has a certain value

Branch Conditional branch only jumps if Accumulator has a certain value

Loops A branch that goes backwards can make a loop to repeat instructions
