Embodiment Construction
[0036]In order to reset the faulty DSP chip, it does not affect the work of the non-faulty DSP chip that is in the same DSP board as the faulty DSP chip, and improves the utilization rate of DSP resources. In the embodiments of the present invention, each DSP chip can automatically obtain this chip The first address ID (Identity, identification) of the system is reported to the system main control processor. When the system main control processor detects that a DSP chip has failed, there is no on-board control processor on the DSP board where the faulty DSP chip is located, and In the case of failure to reset the faulty DSP chip through software reset, the system main control processor sends a message to at least one non-operated DSP on the same DSP board as the faulty DSP chip based on the first address ID reported by each DSP chip to the system main control processor. The faulty DSP chip sends a command to reset the faulty DSP chip, and resets the faulty DSP chip through the ...

The invention belongs to the data communication field and relates to a method for resetting a fault digital signal processor (DSP) chip and a device for resetting the fault digital signal processor (DSP) chip. The method and the device for resetting the fault digital signal processor (DSP) chip are used for improving the utilization rate of digital signal processor (DSP) resource. The method for resetting the fault digital signal processor (DSP) chip comprises the following steps that: each digital signal processor (DSP) chip automatically acquires a first address identity (ID) of the chip, and then reports the first address identity (ID) to a system main control processor; and when the system main control processor finds that a fault occurs on a digital signal processor (DSP) chip, and software reset performed on the fault digital signal processor (DSP) chip fails, and no intra-board control processor exists in a digital signal processor (DSP) board, the system main control processor transmits a command for resetting the fault digital signal processor (DSP) chip to at least one non-fault digital signal processor (DSP) chip which is in the same digital signal processor (DSP) board with the fault digital signal processor (DSP) chip; and the fault digital signal processor (DSP) chip can be reset through the non-fault digital signal processor (DSP) chips. By means of the above technical schemes of the invention, influence on the work of the non-fault digital signal processor (DSP) chips in the same digital signal processor (DSP) board with the fault digital signal processor (DSP) chip, which is caused by resetting performed on the fault digital signal processor (DSP) chip, can be avoided, and therefore, the utilization rate of the digital signal processor (DSP) chip resource can be improved.
Description
technical field [0001] The invention relates to the field of data communication, in particular to a method and device for resetting a faulty DSP chip. Background technique [0002] With the continuous development of communication technology, the application of 3G and IP technology is becoming more and more extensive, and the requirements for the processing capability and flexibility of the telecommunication system are also getting higher and higher. Since the system architecture of the telecommunication system is relatively large, in order to facilitate the maintenance and upgrading of the telecommunication system, the telecommunication system is generally designed in a modular manner, wherein some modules can be added or reduced as required. [0003] In the modular design of the telecommunication system, taking the digital signal processing module as an example, each digital signal processing board, that is, a DSP (Digital Signal Processor, digital signal processing) board,...
