An Integrated SoC for Image Processing in Space Flight Instruments

An integrated SoC called Image processing SoC (Image-SoC), that is aimed at speeding-up the digital image processing capability of space instruments by providing a convenient hardware infrastructure, is proposed in this paper. A RISC-V processor is used in Image-SoC to implement control and monitoring functions. The module composition and data processing process of SoC will be introduced in detail below. In order to enable the use of Image-SoC in deep space mission, the SoC implements the radiation hardening by design (RHBD) techniques based on the EDAC. Finally, The SoC supports multiple working modes to achieve different image processing under different requirements. Logic synthesis results based on SIMC 40nm technology library show that the clock frequency of the Image-SoC can reach 277 MHz.
