This repository contains the SHA-512 Hash Algorithm Implementation in VHDL, optimized for use in digital systems and embedded applications. It provides both a loop-unrolled and an unoptimized version, allowing for a comparison in terms of performance and resource usage. SHA-512 is a secure cryptographic hashing algorithm widely used in data integrity and security applications.
The repository is organized into two main directories, each implementing a distinct version of the SHA-512 algorithm:
loop_unrolled- Contains the loop-unrolled SHA-512 implementation, optimized for performance. This version reduces the number of iterations by unrolling loops, which can significantly improve speed at the cost of increased resource usage.unoptimized- Contains the standard SHA-512 implementation without loop unrolling, following a more straightforward design that is resource-efficient but slower in performance.
CONSTANTS.vhd- Defines constants and parameter values for the algorithm, making it easier to adjust hash size, initial values, and configuration.sha512_core.vhd- Implements the SHA-512 hashing core, handling the main transformation operations of the algorithm.sha512_tb.vhd- A testbench for verifying the SHA-512 core’s functionality, including exhaustive test cases to ensure correct hash computation.
- Dual Implementations: Both optimized (loop-unrolled) and unoptimized versions to meet different performance and resource needs.
- Parameterization: Easily configurable constants for adapting hash settings.
- Comprehensive Testbench: Each implementation includes a testbench with various input scenarios to validate the correctness of hash outputs.
- VHDL Simulator: Ensure you have a VHDL simulator installed, such as ModelSim, Vivado, or GHDL, to compile and run the files.
