Abstract: Aiming at the bottleneck problems of Inkjet printer data processing and transmission , a printer control system based on FPGA and DSP was designed, which used the USB2.0 interface chip CY7C68013A to realize the highspeed data transmission.FPGA and DSP were used as the core control components. The synchronous read and write to CY7C68013A endpoints was implemented by FPGA; SDRAM data access and dynamic refresh control was completed. The print control and motion control on X and Y direction was completed by DSP. The data reception and the data control of the print head was completed by FPGA on carriage board. The design of USB firmware and device drivers and application software has been given. The results indicate that the highly modular designed system are integration and flexibility and easy for maintenance and functional expansion.
