Page 199 The picture data for one-line is transferred from DRAM/P-SRAM to CPU. The CPU performs the picture data processing (encode) for this picture data (FILLER, fill bits are inserted) and again stored into the DRAM/P-SRAM. The stored encoded data is output from DRAM/P-SRAM to the MODEM under the control of CPU.
