Problems solved by technology

[0005] However, the existing monitoring method is to embed the program that realizes the monitoring function into the system function program, which needs to modify the software of the monitored system; and the execution of the monitoring function program needs to occupy the storage space and processing capacity of the monitored system; Monitoring by conditional breakpoints is limited by the storage capacity of the system, and cannot be monitored for a long time

Embodiment Construction

[0017] As shown in Figure 1, the real-time signal processing system includes 2 or more than 2 DSPs (2 DSPs are shown in the figure, namely DSP1 and DSP2), which are connected through corresponding serial ports and perform relevant communication. Here, the DSP serial port adopts a commonly used multi-channel buffered serial port. DSP1 and DSP2 are connected to each other through McBSP. In order to monitor the signal between DSP1 and DSP2, the present invention also utilizes DSP to complete signal monitoring, and the McBSP of the monitoring DSP is connected to the connection serial port of DSP1 and DSP2, as shown in the figure. The illustrated processor can be a DSP of TI Company.

[0018] The McBSP of the present invention can complete the serial exchange of internal and external data, and has considerable flexibility. A general McBSP includes a data input pin DR, a data output pin DX, a receiving data bit clock pin CLKR, a sending data bit clock pin CLKX, a receiving data fr...

Abstract

This invention discloses one real time signal process system non-intruding monitor method and its method, wherein, the method comprises the following steps: connecting the processor to the real time signal process system; real time signal process system connected processors for data transmission and the monitor processor receives transmission data; the processor receives the processed data and sending it to the monitor end for process. The system comprises real time signal process system, monitor processor and data process output end.

Description

technical field [0001] The invention relates to a method and system for monitoring signals between interconnected processors of a real-time signal processing system. Background technique [0002] A complex real-time signal processing system usually includes 2 or more processors (including DSP and MCU), and the processors are interconnected through serial ports or other data paths. Among them, DSP (DigitalSignal Processor) can convert continuous signals into information that computers can process. For example, the voice of people speaking is a continuous signal. In addition, such as light, pressure, temperature, etc. are also continuous signals. These signals are converted into digital signals through an analog-to-digital conversion and sent to the processor for digital calculation. After the processing is completed, the results are converted back into continuous signals through digital-to-analog conversion. General-purpose MCU (microprocessor) can also complete these task...
