System on chip for integrating bar code decoding chip

Abstract

The invention provides a system on chip for integrating a bar code decoding chip, which is characterized by comprising a bar code decoding chip used for decoding an input bar code image and a processor system used for providing a control function for the system on chip, wherein the bar code decoding chip comprises a register group, a bar code decoding pipeline, a master control logic module and abus interface, wherein the register group comprises a command register and a data register; the command register is used for temporarily storing commands, and the data register is used for temporarily storing data; the bar code decoding pipeline is used for processing the bar code image; the master control logic module acquires a processing command from the command register and transmits the bar code image to the bar code decoding pipeline according to the processing command for decoding; and the bar code decoding chip is electrically connected with the processor system through the bus interface. By the settings, the invention integrates the bar code decoding chip and the processor system, and thus, a processor can rapidly visit the bar code decoding chip, and thereby, the burden of research personnel is relieved. The system on chip has the advantages of convenient use, higher decoding speed and lower cost.

Description

【Technical field】 [0001] The invention belongs to the technical field of barcodes, and in particular relates to an on-chip system integrating a barcode decoding chip. 【Background technique】 [0002] Bar code technology is an emerging technology developed on the basis of computer technology and information technology that integrates coding, printing, identification, data collection and processing. Barcode technology is widely used in business, library management, warehousing, post and telecommunications, transportation and industrial control due to its advantages of fast, accurate, reliable and low cost, and is bound to play an important role in the emerging "Internet of Things" applications. role. [0003] Currently widely used barcodes include one-dimensional barcodes and two-dimensional barcodes. A one-dimensional barcode, also known as a linear barcode, is composed of multiple "bar" and "space" units arranged in parallel, and the barcode information is expressed by the ...
