In order to develop the core chip supporting binocular stereo displays for head mounted display （HMD） and glasses-TV, a very large scale integrated （VISI） design scheme is proposed by using a pipeline architecture for 3D display processing chip （HMD100）. Some key techniques including stereo display processing and high precision video scaling based bicubic interpolation, and their hardware implementations which improve the image quality are presented. The proposed HMD100 chip is verified by the field-programmable gate array （FPGA）. As one of innovative and high integration SoC chips, HMD100 is designed by a digital and analog mixed circuit. It can support binocular stereo display, has better scaling effect and integration. Hence it is applicable in virtual reality （VR）, 3D games and other microdisplay domains.
