WebAlmost the entire original ARM instruction set functionality can be achieved with Thumb2. Since the instruction stream is more dense, it is higher performance than the original ARM in almost every case due to lower instruction fetch overhead. Thumb2 allows conditional execution for four instructions with 'if/else' opcode conditions. WebSep 25, 2013 · The original Thumb instruction set only had two-byte instructions, so it read PC+4. When four-byte Thumb instructions were introduced, this behaviour was preserved, so Thumb always reads PC+4 irrespective of the size of the instruction used to read it.
