4.6.1.3. Bitswap Custom Instruction
To add the bitswap custom instruction to the Nios II processor in Qsys, select Bitswap under Custom Instruction Modules on the Component Library tab, and click Add.
The bitswap custom instruction reverses a 32-bit value in a single clock cycle. To perform the equivalent operation in software requires many mask and shift operations.
For details about integrating the bitswap custom instruction into your own algorithm, refer to the Nios II Custom Instruction User Guide.
