http://www.free-ip.com/DES/index.html
The Free-DES core is a basic DES encryption/decryption core. The features are:
Standard DES encryption/decryption algorithm.
Two versions: fast operation and small size.
Triple DES can be done using three passes, or three DES engines.
ECB Mode.
Key can be changed on each 64-bit block with no performance penalty.
Simple synchronous interface.
The applications for this core is numerous, including:
High speed ATM/Ethernet/Fiber-Channel switches.
Secure video teleconferencing.
Routers and remote access servers.
DES key cracking engines.
There are two versions of this core, one for high speed, and the other for small size. The high-speed core uses a 16-stage pipeline, one for each round of DES, processing a single 64-bit DES block every clock cycle. This requires quite a bit of logic to implement, but results in a very fast DES engine. The small version doesn't use a pipeline. Instead it uses an iterated approach. This takes 16 clocks per block, but is also about 1/3rd the size.
Current Version
The current version of the Free-DES core is 1.01. This version is identical to version 1.00, except that HTML documentation is now included in the standard zip file.
