Exploring Various Levels of Parallelism in High-Performance CRC Algorithms
IEEE Access, 2019 Modern processors have increased the capabilities of instruction-level parallelism (ILP) and thread-level parallelism (TLP). These resources, however, typically exhibit poor utilization on conventional cyclic redundancy check (CRC) algorithms.
