Device and method for parallel data transmission and storage based on dual-path data acquisition

Abstract

The invention discloses a device and a method for parallel data transmission and storage based on dual-path data acquisition, and belongs to the field of embedded development. According to the device provided by the invention, a microcontroller is provided with three timers, namely a first timer, a second timer and a third timer; a DMA controller is provided with a first DMA and a second DMA, and a cache region is provided with a plurality of cache spaces. Furthermore, according to the method provided by the invention, once the microcontroller starts the third timer, the mutual control among the timers can replace to trigger the first DMA and the second DMA to respectively carry out data transmission, so that the DMA controller can automatically operate the data transmission, and the pipeline operation of the data transmission is realized. Moreover, the first DMA and the second DMA can synchronously transmit the data received by the two data acquisition modules and put the data into a cache region, so that synchronous parallelism of data acquisition, transmission and storage is kept, resources of the microcontroller are greatly configured, and efficient data acquisition, transmission and storage are realized.

Description

technical field [0001] The invention relates to a device and method for parallel data transmission and storage based on dual-channel data acquisition, which belongs to the technical field of computer embedded development. Background technique [0002] Due to the development of embedded technology in the computer field, the data acquisition has become intelligent; and the wide application of the Internet of Things has also made the current demand for real-time data acquisition more and more, while the acquisition channel of a single external acquisition module is limited, unable Meet the needs of large amounts of data collection. Most of the existing data acquisition methods require more acquisition modules, and a large amount of data is collected and transmitted into the buffer area of ​​the microcontroller and usually needs to be taken out again and stored in an external data storage module. In the case of needing to control product cost, the buffer memory in the microcont...
