Embodiment Construction

[0039] Please refer to Fig. 4, shown in 5, the multitasking processing method based on digital signal processor of the present invention, described digital signal processor comprises a plurality of processing passages, each kind of task occupies at least one processing passage (for example occupies 64 processing passages) , set the main loop process, put the low-priority tasks in the main loop processing; set the interrupt process, put the high-priority tasks in the interrupt process, and the time interval of the interrupt process is less than or equal to the minimum processing of the high-priority tasks time interval.

[0040]The priority of processing tasks is set according to the needs or task characteristics, such as in the voice test of the VoIP network, the preprocessing of the voice files to be sent (including DTMF generation, single tone generation, encoding of voice files, etc.), PESQ calculation , audio index calculation and other parts will take up a lot of DSP reso...

Abstract

This invention discloses a multi-task process method based on a digital signal processor containing multiple process channels and every task occupies a channel at the least. A primary circulation flow is designed to process the task information of the low PRI, an interruption flow is designed to process the task information in high PRI and the time interval of the interruption flow is smaller than or equal to that of the task of high PRI.

Description

technical field [0001] The invention relates to a voice communication technology in the field of network communication, in particular to a multi-task processing method based on a digital signal processor (DSP, Digital Signal Processing). Background technique [0002] DSP is a microprocessor with a special structure specially designed to quickly implement various digital signal processing algorithms. Its processing speed has reached 2000MIPS (Million Instruction Per Second, million instructions per second), faster than the fastest CPU. 10-50 times faster, so it can handle multitasking and can handle real-time tasks. For example, in the voice service test of Voice Over Internet Protocol (VoIP, Voice Over Internet Protocol), because the test analysis of voice is mainly a digital signal processing process, which is the frequency domain analysis of voice digital signal, it is especially suitable for DSP processing. [0003] The main purpose of the VoIP voice test tool is to test...
