Bridge to APB, AHB, and AXI bus SHA2-384 is a universal solution that effectively speeds up the SHA2-384 hash function that complies with FIPS PUB 180-4. It has three options for computing message digests: 256, 224, or 384 bits. The maximum allowed input message length is 264 – 1 bit. The SHA2-384 HMAC (Keyed-Hash Message Authentication Code), a cryptographic mechanism specified in RFC 2104, is also natively supported by it, depending on the core settings. In digital signature protocols and usually in secure communication, this IP is appropriate for authenticity and data integrity checking. It might potentially be applied to speed up bitcoin calculations. Additionally, it has a context-swapping function that might be helpful in intricate systems when a task's preemption mechanism is in place.
