Parent asked about energy consumption, not speed.
You can program in floating point (I'm doing just that, with 6 cores performing Karatsuba-3 multiplication of 54-bit elements) but that is quite a bit slower than hardware DP multing (which Parallella boards lack too). FP multing will likewise be slower than hardware FP multing, which Parallella does have.
- solarexplorer 13y agoSure, you can do floating point in software. My point is that dedicated hardware is very likely more power efficient at it. The same goes for memory: accesses to off-chip memory cost much more energy than accesses to on-chip memory. It would be very interesting to get energy and performance numbers for some real world application running on both chips.
