newRPL running the N-Queens benchmark on the 50g hardware is old news. We published some very early benchmarks in the article Running on 50g hardware.
But back then the newRPL core was running under the HPGCC3 environment, and without support for real numbers yet.
Now we introduce the first test run of the same benchmark running as an independent firmware. The average time for 10 runs is 226 ms at the normal speed for newRPL (normal speed means the first 500 ms running at 6 MHz, then switches automatically to 192 MHz until the code finishes).
This is running with the final version of the memory manager, a real garbage collector, among other things. While some optimizations in the RPL core are possible, this speed of execution is satisfactory.
