Method for improving code and decode treatment efficiency

Abstract

The invention relates to a method to improve code-decode efficiency, which comprises: presetting a first buffer block between code / decode pre-process unit and coder-decoder and a second buffer block between coder-decoder and code / decode post-process unit; the said pre-process unit writes the data into empty buffer zone in the first block; the coder-decoder obtains data from nun-empty buffer zone of the first block for coding / decoding and send the treated data to the empty buffer zone in the second block; the said post-process unit obtains treated data from nun-empty buffer zone of the second block for coding / decoding. This invention can reduce time delay, improves system capacity, and brings device treatment performance into play.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for improving the processing efficiency of encoding and decoding. Background technique [0002] At present, encoding and decoding processes have occupied a very important position in the communication field. In the whole encoding and decoding process, three processing steps are usually required: pre-encoding / decoding processing, encoding / decoding and post-encoding / decoding processing. The encoding / decoding system composed of the encoding / decoding pre-processing unit, the encoding / decoder and the encoding / decoding post-processing unit is widely used in different communication processes by providing a flexible interface to the outside. [0003] Take the uplink decoding process of the baseband part of the WCDMA system as an example, as shown in figure 1 As shown, the decoding system combines digital signal processing (DSP, Digital Signal Processing) with programmab...

Problems solved by technology

[0005] The defect brought by this method is: since the pre-decoding processing unit, the decoder and the post-decoding processing unit work in serial mode, that is, after the previous unit completes the processing and sends the data into the buffer, the latter unit The data can be obtained from the buffer to continue processing. Therefore, in this working mode, the processing delay in the decoding process is relatively large, and the system processing efficiency is low.

In the decoding processing system, the DSP and the decoder are two independent functional units. In order to improve the decoding processing efficiency of the system and shorten the processing delay in the decoding process, on the basis of the existing technology, usually the The processing capacity and device processing speed of each unit processing device are improved, but due to the limitation of the decoding processing method in the prior art, each processing device is still often in an idle state during the entire decoding process, and then in the decoding process Unable to give full play to the excellent performance of the device

[0006] To sum up, simply improving the processing capability of the device cannot effectively solve the above technical problems, and also increases the system cost
