iPod Classic: disable IRAM1
On Classic, IRAM1 (second 128Kb of a total of 256KB available IRAM) is slower than DRAM. Codecs that actually are using regions of IRAM1 runs faster when DRAM is used, so IRAM1 is disabled and only IRAM0 remains enabled: 48KB for core and 80KB for codecs/plugins. The next test_codec results shows how decode time is decreased: file boosted unboosted *.ra ~1.5% ~0.5% *.mpc ~21% ~4.5% *.ogg ~0.5% ~0% nero_he*.m4a ~8% ~1% nero*.m4a ~25% ~7% wmapro*.wma ~4.5% ~0% wma*.wma ~25% ~7% In addition there is a small power save when IRAM1 HW is disabled.
