Came to interesting RLP performance comparison, 4.2 vs. 4.3…
The task: calculate 16bit CCITT CRC.
EMX: 77ms vs. 5ms (18x)
G120: 39.36ms vs. 3.26 (12.1x)
G400: 4.21ms vs. 0.49ms (8.6x)
Cerberus: 13.11ms vs. 0.90ms (14.6x)
EMX: 76.85ms vs. 6.34ms (12.3x)
G120: 39.27ms vs. 2.22 (17.7x)
G120 (overclocked): 29.71ms vs. 1.46 (20.4x)
G400: 4.04ms vs. 0.41ms (9.8x)
Cerberus: 12.54ms vs. 0.64ms (19.7x)
The results are unexpected. G120, G400 and Cerberus are significantly [em]faster[/em], while EMX is significantly [em]slower[/em]. How’s so?..
