| Nios II Custom Instruction Design Example - Stratix IV GX FPGA Development Kit|
|This design example shows how to implement the cyclic redundancy check (CRC) algorithm as a Nios® II custom instruction. The CRC algorithm detects the corruption of data during transmission. The CRC calculation consists of an iterative algorithm involving XOR and shift operations. These operations are carried out concurrently in hardware and iteratively in software. Since the operations are carried out concurrently, the execution is much faster in hardware. This example demonstrates the way to implement an extended multi-cycle Nios II custom instruction. |
