Abstract: Based on the development of a digital video acquisition and processing board-level system, this paper proposes a design scheme for a motion vision processing and control system using SOPC. The system hardware utilizes Stratix II series FPGAs, and the software development tools include Quartus II, Nios II 5.1 IDE, DSP Builder, MegaCore IP Library 5.1, and Matlab 7.0. It can be widely applied in security monitoring, visual navigation, intelligent transportation, and many other fields. Standard I/O ports are also reserved for future upgrades and expansions. Keywords: Motion vision; Video image; SOPC; FPGA With the development of deep submicron technology, the capacity and density of FPGAs are constantly increasing. With their powerful parallel multiply-accumulate (MAC) operation capabilities and flexible dynamic reconfigurability, they are widely used in many fields such as communication and image processing. However, in implementing complex algorithms, FPGAs are not as convenient as embedded processors. Therefore, when designing systems with complex algorithms and control logic, it is often necessary to combine them with embedded processors. This is the SOPC (System on a Programmable chip) technology. SoPC is a product of the combination of SoC and FPGA, with a single programmable and reconfigurable chip performing the main functions of the entire system. SoPC design is flexible and versatile, and can be designed using schematics, hardware description languages, or even high-level languages ​​like C/C++. It also features reconfigurability, scalability, and expandability, making upgrades convenient. SoPC combines the advantages of both SoC and FPGA, possessing the following characteristics: ● Abundant IP core resources, including general-purpose and dedicated IP cores ● In-system programmability, simplifying design, compilation, downloading, and debugging ● Built-in embedded soft-core processor, memory, and peripheral interface controller ● Numerous programmable and reconfigurable logic resources ● Powerful clock management circuitry ● Support for multiple I/O interface standards. Furthermore, due to the reduced transmission line distance between the processor and memory, SoPC offers significant advantages over board-level systems in terms of speed, signal integrity, and electromagnetic compatibility.
