High speed data transmission and storage system based on SoC

Abstract

The analysis and application of real-time and high-resolution images have attracted increasing attention of researchers, and are gradually increasing in artificial intelligence, civil engineering, remote sensing and other fields. Currently, array cameras are often used to obtain high resolution images. This study aims to research and design a transmission and storage scheme based on PCIE Peer-to-Peer transmission and SATA Array storage, which can meet the needs of high-speed data transmission and storage of industrial array camera. The whole design is divided into transmission and storage. Transmission uses Peer-to-Peer, high–bandwidth PCIE bus. The interface of the storage side is SATA. By defining and designing the external interface of SATA Host flexibly, we can realize a directly connection between the data to be stored and the SATA Host interface, which can save resource cost and meet the requirements of high transmission efficiency and strong scalability. Through PCIE Switch, the design transfers the data of multiple ports to the SoC directly for hard disk storage, which has the advantages of small size, fast speed and strong extensibility. This paper designed the Peer-to-Peer transmission and storage experiment of multiple channel. The feasibility of the design was fully demonstrated and obtained the relevant transmission performance parameters.
