Embodiment Construction

[0020] Below we provide a better embodiment of the present invention according to Fig. 1-Fig. 4, so that those skilled in the art can more easily understand the above-mentioned characteristics of the present invention, a slice of vocoder realized from the voice processor (DSP) in the embodiment The number of devices is n=3.

[0021] Please refer to Fig. 1, a vocoder resource board 10 contains a main control CPU 101 and several digital signal processors 104, there is a large amount of data interaction between the main control CPU 101 and each digital signal processor 104 on the board, There are several data buffers 102 between them, and each data buffer 102 is divided into a forward service frame buffer 1021 and a reverse service frame buffer 1022, and what the forward service frame buffer 1021 stores is composed of digital signals For the service data frames sent by the processor 104 to the main control CPU 101 , the reverse service frame buffer 1022 stores the service data fr...

Abstract

A resource distribution method and its device in CDMA voice coder time applies mainly a code / decode module of multi-offset distribution meter-dispatch voice coder unit. The main controller CPU timely fetches forward service frame and reported by each digital signal processor which autoamtically fetches timely the backward service frame written in definite address. The processed device contains main controller CPU and several digital signal processors added by several data buffer zones and a control logic part providing time interrupt identification to main controller CPU, data buffer zone and digital signal processor and resource distribution control program stationed in CPU to attain the aim of separate loads of multiple digital signal processors and reduce overhead by CPU.

Description

technical field [0001] The invention relates to a method and a device for allocating time slice resources of a code division multiple access (CDMA) vocoder in a code division multiple access (CDMA) system. Background technique [0002] In the CDMA system, the channel unit (CE) located on the base transceiver station (BTS) side has strict time alignment requirements, and transmits and receives service frames at a fixed time slice interval of 20 milliseconds, so that the base station controller ( The vocoder unit (VE) on the BSC) side has certain timing requirements when sending and receiving service frames, and must receive the reverse service frame from the channel unit and send the forward service frame to the channel unit within a fixed time window of 20 milliseconds. At the same time, there is a large amount of data interaction between the main control CPU and the digital signal processor (DSP) on the resource board of the vocoder. Especially when the resource board is wo...
