Line 9:
Integer arithmetic operators can also effect bit-operations in conjunction with the other operators.
Bit manipulation, in some cases, can obviate or reduce the need to loop over a data structure and can give manyfold speed-ups, as bit manipulations are processed in parallel. However if the operation is unusual or costly to implement its inclusion cannot be justified, inspiring innovative research.<ref>https://www.researchgate.net/publication/4217315_Performance_and_energy_benefits_of_instruction_set_extensions_in_an_FPGA_soft_core</ref>
