Enable "cache" command on Qong board and test performance. Test 1: Loading 127 MB of data from NAND flash into RAM: Instr. Cache off on on Data Cache off off on -------------------------------------------------- QONG (ARM11) 177s 95s 43s = x 4.1 Test 2: uncompressing a gzipped image from RAM to RAM (size compressed: 6.5 MiB, uncompressed: 35 MiB): Instr. Cache off on on Data Cache off off on -------------------------------------------------- QONG (ARM11) 1.54s 0.95s 0.18s = x 8.6 Portions of this work were supported by funding from the CE Linux Forum.
