How to mapping RGB data in IPU?

Dear all,

     I'm developing display driver for wince7 on an i.MX53 board, my code is based on the BSP of i.MX53 SMD board, when I output some picture data to a TFTLCD display, I found that there are two data mapping modules which are in IDMAC's Format Convert Write & Read module and DC's Bus Mapping Unit, could anybody tell me how do these two modules work? what's the input/output of these modules? And must I use both the modules or just use one of them is OK?

     Thank you very much.

Hi, Yuri

       Thank you for the helpful answer, now I know that how the DC's Bus Mapping Unit works, but I'm still confuse about the IDMAC's Format Convert Write & Read module, in the SMD BSP code, it seems that the picture data is unpacked by the FCR module before go to DMFC, there is a mapping process which based on some mapping parameters stored in CPMEM, could you tell me how does this work and what the purpose is?

       Thank you very much.

Please try to create separate thread regarding Format Convert Write & Read module - it the issue is still actual.
