Reconfigurable and router-like hard-core coder with multi-protocol

Abstract

The invention provides a reconfigurable and router-like hard-core coder with multi-protocol. Source data and control data of various communication protocol layers are uniformly converted into a self-defined BIN-CODE data structure, an MRC routing table is constructed according to the BIN-CODE data structure, a coder hardware structure is reconstructed according to the constructed MRC routing table, and the coder is configured according to the MRC routing table and the control data. The reconfigurable and router-like hard-core coder with multi-protocol provided by the invention can support thedata coding of a plurality of communication protocols and a plurality of coding modes, and an output serial code stream can be adapted to a plurality of transmission media. The coder provided by the invention has a strong coding function, a high resource utilization rate, high coding abnormality handling ability, high expansibility and a wide application scope.

Description

technical field [0001] The invention relates to a multi-protocol reconfigurable routing hard-core encoder, which belongs to the technical field of communication and microelectronics. Background technique [0002] With the rapid development of mobile payment technology and industry, many novel payment technologies have emerged, which are mainly divided into two categories: one is remote payment technology, mainly represented by Alipay, WeChat, UnionPay wallet and other payment technologies based on mobile apps; The second category is near-field payment technology, mainly represented by UnionPay QuickPass (contactless IC card), ApplePay, Huawei Pay and other payment technologies based on near-field communication (NFC). Various payment technologies can realize data interaction between the payment device and the collection device on the transmission medium, and the communication data between the two needs to be encoded by the encoder to be suitable for transmission through a spe...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, according to the existing encoder implementation method, multiple encoders corresponding to various communication protocols need to be configured on the payment device to realize encoding, which not only wastes the hardware resources of the device, but also increases the cost, and requires the user to master each communication protocol. The characteristics and principles of the encoder can be used; in addition, the sequence, length and content of the code stream data segments output by the existing encoder must follow the rules of the corresponding encoding method. Errors in fragments may cause error accumulation or error propagation, resulting in the unrecoverable or slow recovery of the encoding ability of the encoder, affecting the payment function
