A Zynq-based multi-axis multifunctional motor position decoding system

Abstract

The invention discloses a ZYNQ-based multi-axis multi-functional motor position decoding system, which includes a processor system unit and a programmable logic unit that can perform data interaction on the ZYNQ chip. ARM module for parameter configuration and data processing on the programming logic unit. The programmable logic unit is equipped with: a decoding module for decoding various encoder signals input by an external motor; an eight-bit parallel port module for external processors. The corresponding interface is provided when accessing the internal register; the selector module is used to selectively input the motor encoder signal to the corresponding decoding module for decoding; the human-computer interaction module is used to realize the data interaction between human and machine. The invention effectively improves the real-time performance and synchronization of encoder signal decoding by centrally setting various decoding modules on the programmable logic unit for parallel decoding, and at the same time greatly relieves the burden on the CPU, providing more complex algorithms. favorable conditions.

Description

technical field [0001] The invention relates to the field, in particular to a ZYNQ-based multi-axis multifunctional motor position decoding system.
