ignored (help)The new A19 relies on "super-scalar" techniques from scientific computers to execute many instructions concurrently. The A19 can overlap as many as 140 operations, more than 10 times as many as conventional mainframes can.
This flexibility improves performance since it allows execution with less 'waiting' time.
The algorithm "allows sequential instructions that would normally be stalled due to certain dependencies to execute non-sequentially" (also known as out of order execution).
don't wait for previous instructions to execute if this instruction does not depend on them
