1. The ISS questions:
Reference data: SPRUH30_ISS. PDF
1-1. The ISS (imaging subsystem working position)
ISS receive signals from sensor output data, because we use ar0331 parallel output, and successfully configuration ar0331 register default output for 1080 p30 frame, make sure ar0331 work clock, vertical, horizontal sync signal and video output have signal
Question 1: ISS work in what position, is located in the A8, VPSS M3, video M3 or C64X DSP core
Question 2: VPSS M3 core of capture - display module, RGB bayer YUV format turn in ISS module ISP (ISIF IPIPE) processing or in VPSS core processing, which is a correct data processing procedure:
Sensor - ISS --VPSS-- VIDEO M3
Sensor - ISS -- VIDEO M3
Sensor -- VPSS - VIDEO M3
Question 3: VPSS and VIDEO M3 core how to control the ISS such as lens distortion correction, noise reduction, H3A, have more related information
Question 4: how to validate the ISS module normal work, which register need configuration,register configuration process
