Claim 19:
20. The computer program product of claim 19, further comprising:
performing, by the n-bit accelerator, another arithmetic operation using the high-part packed integer and a predetermined constant u, the predetermined constant u being dependent, in part, on the bitwidth k, where performing the other arithmetic operation generates another intermediate result comprising multiple result components;
shuffling and repacking the other intermediate result to obtain another high-part packed integer, the other high-part packed integer being another n-bit integer comprising multiple slots, where high-order parts of the multiple result components of the other intermediate result are packed into every other slot of the multiple slots; and
using the other high-part packed integer in facilitating obtaining the result data which facilitates the cryptographic-related processing.
