The SDE and DOF engines always work only on pixel data that is organized in a fully packed 12-bit format. These accelerators do not support any other input pixel data formats. To support other data formats, two format conversion modules (FOCO_0 and FOCO_1) are included inside the DMPAC sub-system. The FOCO converts other data formats into the data format supported by the SDE and DOF engines. Figure 6-161 shows how the format conversion engine sits inside the DMPAC sub-system.
Figure 6-161 DMPAC with Format Conversion Engine (FOCO)The FOCO operates in a SL2 memory-to-memory processing fashion. The DMA engine brings the data into the SL2 which is then read by the FOCO, converted and written back into SL2 to be consumed by the SDE and DOF engines. Figure 6-162 shows the data flow with the format conversion engines.
