MD5 Cryptographic Hash Function - Hardware and Software
The main idea of this project is to implement a system where:

The most complexity part is implemented on hardware (MD5 hash function)
The interaction is implemented on software
To explore the complexity and to compare two approaches:

We developer a script to implement MD5 in C and compare the performance of three approaches:

All on software
All on hardware
MD5 on hardware and interaction on software
The implementation will be based on this paper: Hardware implementation of the MD5 algorithm.

Structure of the project:

MD5Demo: Hardware + Software approach
hardware-md5: approach just on hardware
md5.c : script in C of MD5
ip_repo: IP Core to Hardware + Software approach
simulation: testbench
Requirements
Vivado 2019.2
Vitis
Nexys4 Digilent Xilinx (FPGA)
Implementation
On Vivado was implemented a version just on hardware with an IP Core to MD5.
Then, it was implemented a version with IP Core on hardware to implement MD5 and all the control on software. Input data came from software to hardware by DMA and all the process occurs on hardware. When the process finishes, the data produced on hardware is transmitted by AXI Memmory Mapped Interface to software to show the user.
