Cyclic Redundancy Check (Crc): The cyclic redundancy check (CRC) library provides bitwise, table-based, and (if available) hardware-assisted computation of CRCs using different 8-, 16-, and 32-bit generator polynomials, namely, the SAE-J1850 CRC8, the CCITT-FALSE CRC16, and the IEEE-802.3 CRC32 used for Ethernet.

Sioh Lee et al. (2017) implemented an advanced KSM approach for Cloud computing [25]. The authors presented a page grouping approach to decrease page comparisons in prior work, but it demands specific monitoring hardware. XLH improved memory page sharing by including information about guest virtual machine I/O operation. However, XLH’s CPU overhead remains considerable, equivalent to that of the normal KSM. To CPU cycles. Based on the findings of the simulation, a KSM advanced for cloud computing (AKC) that uses fewer cycles of CPU than the default KSM was developed. Checksums based on the RB-tree structure were used to decrease the number of page comparisons. AKC also uses a hardware-accelerated CRC32 hash algorithm to reduce page checksum overhead.
