A chip architecture suitable for two-dimensional barcode decoding chips

Abstract

The invention relates to a chip structure applicable to a two-dimensional bar code decoding chip. The chip structure comprises a GRLIB base, an AMBA (advanced microcontroller bus architecture) bus structure and a custom IP (Internet protocol) inner core, wherein the BRLIB base is used for building a system on a chip based on an Leon3 processor, and comprises the following modules including the Leon3 processor, a JTAG (joint test action group) debugging chain, a debugging support unit, an AHB (advanced high-performance bus) bus controller, an internal memory controller, an SVGA (super video graphics array) controller, an AHB / APB (advanced high-performance bus / advanced peripheral bus) bus bridge, an interruption controller, a timing / counting device, a serial port controller and universal input / output equipment, the AMBA bus structure is used for connecting and organizing each module arranged inside the chip, and the custom IP inner core comprises the following modules including a camera interface module, a data flow control module, a QR (quick response) code decoding module and a system configuration register group. The invention aims at designing a special decoding chip structure for the two-dimensional bar code, the image data is collected through a special hardware module, and the image processing and the decoding operation are carried out, so the processing speed is accelerated, the system integration degree is improved, and the system power consumption and the development cost are reduced.

Description

technical field [0001] The invention relates to the technical field of barcode identification, in particular to a decoding chip architecture suitable for two-dimensional barcodes. Background technique [0002] Barcode recognition technology is an economical and practical automatic recognition technology produced and developed in computer application and practice. Barcode recognition technology is widely used in logistics, transportation, e-commerce, postal services, library management and other fields because of its fast input speed, high accuracy, low technical cost, and strong reliability. With the development of the Internet of Things industry, barcode recognition technology, as one of the basic technologies of the Internet of Things, is bound to continue to play an important role in the application of the Internet of Things. [0003] The current mainstream barcode recognition technology mainly includes one-dimensional barcode (or barcode) and two-dimensional barcode. T...

AI Technical Summary

Problems solved by technology

However, this solution is limited by processor computing performance and software algorithm optimization, slow processing speed, high system power consumption, low integration and high production cost

Under the background of more and more widely used two-dimensional barcodes, traditional software decoding solutions obviously cannot meet the needs of two-dimensional barcode development, which limits the development of two-dimensional barcode technology
