Heiko Schocher c3330e9d6a ARM (ARM926ejs): add data cache support, tested on magnesium and tx25 board ... Enable "cache" command on tx25 and magnesium 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 -------------------------------------------------- magnesium 32,6s 22,5s 30s = x 1,09 tx25 (29MB only) 9,69s 5,05s 8,16s = x 1,19 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 -------------------------------------------------- magnesium 4,25s 2,08s 1,72s = x 2,47 tx25 4,82s 2,04s 1,84s = x 2,62 Portions of this work were supported by funding from the CE Linux Forum.
