Abstract

The invention discloses a DSP serial port communication reliability detection system and method. The DSP serial port communication reliability detection system and method carry out pre-detection of bidirectional data transmission of a serial port chip and a drive circuit to guarantee that the circuit starts the external communication after being safe and reliable. The a DSP serial port communication reliability detection system and method are characterized in that an FPGA is used for carrying out communication testing on the serial port circuit, and the rear-stage switch is opened after success, so as to guarantee that the serial port hardware state is good when an application program is executed, and the system reliability is improved.

Description

technical field [0001] The invention relates to a DSP processor serial port communication reliability detection system and method. Background technique [0002] With the rapid development of embedded computers, DSP-based technology has become more and more widely used, and has penetrated into almost every information field, including industrial control, information processing, aerospace, communication equipment and other industries. Among them, TI's DSP6000 series processor has become a widely used DSP processor. [0003] Generally, the traditional DSP serial port communication design scheme is DSP+serial port chip, and the software directly controls the chip to send and receive data. Due to the influence of factors such as the aging of electronic components, there may be problems with the hardware between the DSP and the peripheral interface, and it cannot communicate with the outside world and cannot report faults. Only tools such as oscilloscopes can be used for measurem...
