whitefire had stated that this algo was meant to test the thermal limits and insure the functions. if this one works for you, he said all the others will work.......
IMHO, He start this algo only for this reasons:
1) This algo already was released for FPGA and placed as VHDL/Verilog sources at github. OP does not wrote his own hashing-core design, He done only adaptation to specific FPGA-board;
2) This is a very simple and smallest hashing algorithm that can get maximum performance on FPGA. Any other algos discussed in this threads will use a more FPGA's logic cells and therefore it
will cause a less performance (profitability).
