Overview

The SHA-256 encryption IP core is a fully compliant implementation of the Message Digest Algorithm SHA-256. It computes a 256-bit message digest for messages of up to (2**64 – 1) bits.Developed for easy reuse, the SHA-256 is available optimized for several technologies with competitive utilization and performance characteristics. Support for the AMBA bus interface is available as an option.

Features

  • Designed according to the FIPS 180-2 Standard
  • Maximum message length up to (2**59 – 1) bits
  • Throughput: 7.9 Mbits/MHz
  • Size: 1,180 ALMs
  • Deliverables include test benches, C model and test vector generator

Device Utilization and Performance

The core can be mapped to any Intel® FPGA Family and optimized to suit the particular project's requirements. The SHA-256 core synthesizes to 1,180 ALMs. On Intel Arria® 10 device, the core can run at least 100 MHz providing a throughput of 787 Mbps.
