Description
Summary:This paper presents high speed image data transmission using MIPI(mobile industry processor interface) CSI-2(camera serial interface) interface for high resolution touch panels. On MIPI CSI-2, the receiver corrects 1bit error on the header of packets, but just checks errors on the data of packets without correction. If there are errors, the receiver notices these errors to upper layer including application layer. Error-handling is a duty of application layers that will bring touch response delay consequently. In this work, we added an error handling path to low level protocol layer. In addition, to compensate signal attenuation due to increasing transmission distance, the adaptive equalizer using FVC(frequency-voltage converter) was applied to the receiver. The proposed architecture was tuned with 800Mbps that transfers data of 800×600 high resolution panels less than 10ms with a single data lane.
