Architecture capable of interconnecting HART communication protocol chips and use method thereof

Abstract

The invention provides an architecture capable of interconnecting HART communication protocol chips and a use method of the architecture. The architecture comprises a power supply module, an AXI4 bus module, a CLK clock management module, an RAM data storage module, a data frame analysis module, a longitudinal parity check module, a data packaging module and a signal modulation and demodulation module. The working method of the architecture specifically comprises: a method for sending data by a chip, i.e., when a CPU writes data into slave equipment, receiving the data by the chip and storing the data by the chip into an RAM and a register stack, packing the data after longitudinal parity check, and modulating a data signal into a square wave to serve as a chip output signal; and a method for sending data by a chip, i.e., converting a received square wave signal into a digital quantity, transmitting the digital quantity to the data frame analysis module to analyze DATA data bytes, storing the DATA data bytes in the RAM memory after longitudinal parity check, and finally uploading the DATA data bytes to a CPUfor processing through an AXI4 bus. According to the invention, the HART chip is more flexible, unified and standardized; and the data interaction between the CPU and the HART chip is improved.

Description

technical field [0001] The invention relates to the field of chip manufacturing, in particular to a structure of an interconnectable HART communication protocol chip and a method for using the same. Background technique [0002] The chip industry is the upstream of the manufacturing industry. It is called "industrial food" and is an indispensable core technology for the manufacturing industry.
