Problems solved by technology

However, the MCU itself cannot support complex graphical interface display and rich peripheral interface expansion.
In practical applications, two single boards of the display screen and the controller are often required. There is a large amount of data communication between the two single boards, which causes unnecessary bus occupation and affects the efficiency of bus communication.
MCU-based embedded development platform, because the operating frequency, memory and storage are not large, it is difficult to run large applications, developers are difficult and time-consuming to develop applications

Abstract

The invention relates to a jacquard glove machine control device and method based on heterogeneous dual cores. In a conventional jacquard glove machine control system, a controller needs to issue a control command to each slave board in real time in the actual knitting process of a glove machine. An MCU is adopted as a core controller to operate a real-time operating system in order to ensure strict time sequence in the knitting process, but the MCU is limited in FLASH and RAM capacity in a limited chip, the operation processing capacity of the MCU is limited, a display screen of the glove machine needs to be driven by an additional processor to display, and the controller and the display screen need additional communication interaction. According to the invention, a built-in inter-core shared memory communication mode of a single chip is fully utilized, large-data-volume rapid communication between the main processor and the coprocessor is realized, a complex bus communication protocol is avoided, and the execution efficiency of the controller is greatly improved.
