Research on Computer System Implementation of ISO14443B Protocol Communication Data Acquisition based on FPGA

Abstract

As a programmable logic device, FPGA can be used as a bridge for logic adaptation and timing matching between chip components. For example, in a data acquisition system, data of ten channels need to be collected at the same time. In this case, ten identical data acquisition modules can be instantiated in the FPGA to connect ten external data sensor chips respectively by taking advantage of the parallelism of FPGA, so as to realize the logical adaptation of chip devices. In certain applications such as audio processing, video processing, digital communications, encryption, decryption, etc., as a result of the FPGA computing can parallelism, and FPGA is algorithm Yu into hardware, namely a logic gate and a register, so its execution efficiency usually than machine code and assembly language of single thread special micro processing, the need to replace DSP parallel supercomputing occasions and microprocessors.
