N.1 Institute for Health, Singapore, Singapore 1 2 Retinal prosthesis (RP) electrically stimulates the retinal cells of the blind to restore visual loss, and it is essential to increase the number of channels for higher spatial-resolution information [1]. Conventional RP SoC with an external camera and an image processor has a limitation of increasing the number of channels due to bandwidth bottleneck, and power consumption from high supply voltage
