Network data communication equipment and method for adjusting data processing capacity dynamically

Abstract

The invention provides a network data communication device which uses the DSP for data communication, comprising: a master processing unit, a data exchange / conversion unit and a data processing unit, wherein, the data processing unit comprises one or several DSP slots while each DSP slot is inserted one DSP bar which contains one or several DSP chips; each DSP slot has one or several groups of DSP interfaces relative to the one or several DSP chips of inserted DSP bar; the master processing unit read the condition information of present inserted DSP chip from the data processing unit and controls the data exchange / conversion unit according to said condition information. The invention also provides a method for dynamic adjustment of data processing ability which can be applied in network data communication device. With said device and method, the data processing ability of network data communication device can be adjusted dynamically according to actual demand and the cost of exploitation and maintenance can be reduced.

Description

technical field [0001] The invention relates to network data processing technology, in particular to a network data communication device whose data processing capability can be dynamically adjusted, and a method for dynamically adjusting data processing capability. Background technique [0002] With the rapid development of network technology, the applications of using the network for data transmission are also increasing day by day, such as Voice over IP (VoIP, Voice over IP) and Video over IP (Video over IP). Accordingly, network data communication equipment has gradually become an important network equipment. [0003] According to different uses, network data communication equipment can be divided into network voice communication equipment, network video communication equipment and other types. These network data communication devices undertake the task of sending and receiving data in a network environment. Moreover, an important function of these network data communic...

Problems solved by technology

[0007] The disadvantage of this technical solution is that after the network voice communication equipment is implemented, the DSP resources of the equipment are fixed, so the voice processing capability that the equipment can provide is also fixed, and the voice processing capability cannot be dynamically adjusted according to actual needs.

If the voice characteristic specification of the network is lower than the capability of the existing equipment, there are idle DSP chips in the equipment. Due to the high cost of the DSP chip, the utilization rate of the equipment is low; if the voice characteristic specification of the network exceeds the capability of the existing equipment, then Existing equipment cannot be used, and new equipment needs to be designed and developed separately, which will increase the cost of development and design, and correspondingly increase the cost of software development and maintenance

[0008] Moreover, if the DSP chip fails during the use of the network voice communication device, such as man-made damage or chip aging, the entire device needs to be repaired, which further increases the maintenance cost
