In general, the output bandwidth and printing speed of digital inkjet printer are limited as PC isn't capable of transposing large quantities of image data bit-by-bit in real-time. A new high-speed data processing system based on PowerPC processor and Virtex-5 series FPGA is proposed, and a high-efficiency transposition method is achieved by using FPGA.Three independent DDR2 controllers are instantiated inside FPGA and system output bandwidth is improved by the collaborative work among these controllers; bi...
