SystemC DES is a implementation of the DES algorithm in SystemC focusing on low area applications.
Implements the encoder and decoder in the same block.
It was fully verified using TLM (Transaction Level Modelling Style) defined in the SystemC Verification Library.
Verilog translation for synthesis is also provided.
The core was tested on a Virtex2 FPGA succesfully.
This work is given by Universidad Rey Juan Carlos (Spain)


- SystemC and Verilog code are provided
- Verified using TLM(Transaction Level Modelling Style)
- Encoder and decoder in the same block
- Synthesis Results:
Comparation between SystemC DES project and DES IP project
Synthesis results for a Xilinx XC2V1000FG456-4
Area: 11%
Freq.: 167 Mhz
Cycles per block: 16
- SystemC DES
Area: 4%
Freq.: 90 Mhz
Cycles per block: 16

If you need a more troughput choose DES IP core.
If you need less throughput but want half area choose SystemC DES
