Hi I've built soft float toolchain (with crosstool) and then build MPlayer with it. The performance is very low. I cannot even play the mp3 file with MPlayer on DBAU1200 with 400MHz CPU! I used GCC: 3.3.5 GLIBC: 2.3.5 BINUTILS: 2.16.1 I did some profiling and this is what I get: ----------------------------------------------------------------------------------- Flat profile: Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls s/call s/call name 18.09 44.70 44.70 __pack_f 17.30 87.44 42.74 _fpadd_parts 15.82 126.54 39.10 __mulsf3 15.28 164.31 37.77 __unpack_f 6.49 180.36 16.05 _fpadd_parts 5.30 193.45 13.09 17424 0.00 0.00 dct64_1 4.75 205.18 11.73 __subsf3 4.04 215.16 9.98 __addsf3 3.68 224.26 9.10 17424 0.00 0.00 synth_1to1 1.90 228.96 4.70 __pack_d 1.20 231.92 2.96 __unpack_d 1.17 234.80 2.88 __muldf3 ----------------------------------------------------------------------------------- As it seems, all the time is spent in the FP routines. I decided to use SF toolchain, because they should be faster then FPU emulator (at least it is on ARM), but did no test this with emulator. Does anybody use MPlayer on MIPS? What performance do you get? Any other suggestions? BR, Matej
