Hi list. I decided to do and share some additional tests related to glamo bus speed.
This tests related to change found by Thomas White early this year to GLAMO_REG_LCD_A_BASE2 which change some kind of fifo. Goal of this test is to find out how this change influence glamo speed and how different different fifo settings. So, i did 20 frames of memsets to 480x640 framebuffer, here is test results. First i did tests with different FIFO settings and 2-4-2 timings, and go absolutely same results in each tests. So here is only test results for FIFO = 0 or FIFO = 1 (0x4000): FIFO 0 1 2-4-2, 10Mb/s 17.5Mb/s 4-4-4, 8.1Mb/s 12.2Mb/s Also, please notice that with current settings, we still have huge diff between theoretical and real thoughtput: 23.8Mb/s vs 17.5Mb/s. May be it's possible to avoid that somehow.
