How to transfer variables from arm to dsp

could anyone help me ?

I have a variable  "Analysis_Begin" in the ARM application code.it uses to call different code in DSP server.But I notice only the first value of Analysis_Begin(FALSE) was transferd.
specifically,In the first 10 frames,Analysis_Begin=0,the code(Vanalytics_process)should execute init process.in other frames,Analysis_Begin=1,the code(Vanalytics_process) should execute Analysis process.
But I only see the output of init process.It means Analysis_Begin always equal to 0 ! I want to know how to transfer the  changed value of  "Analysis_Begin".
 

Thanks !

ARM(application code)：
/* Analysis_Begin=FLASE.process initialization. */
       DBG("got buffer from capture thread hVidBuf\n");
       VanalyticsParams.Analysis_Begin=FALSE;
       Vanalytics_process(hVaEnv, hVidBuf, hDisplayBuf);
 
......

/*Analysis_Begin=TRUE,process Analysis. I can see the DEBUG info, But it still executes initialization instead of analysis */
 DBG("Got %d frames , Analysis Begin\n",frame_count);

 VanalyticsParams.Analysis_Begin=TRUE;
 Vanalytics_process(hVaEnv, hVidBuf, hDisplayBuf);
  DBG("    Analysis is processing ");




DSP code:

In algorithm code motion.c,the display depends on variable  "Analysis_Begin":

/* Analysis_Begin=FALSE.initialize parms. */
    if (Analysis_Begin ==FALSE)
       {

VLIB_initMeanWithLumaS32(currentmeans,pLocalBufIn,pixnum);

VLIB_initVarWithConstS32(currentVars, initialVar, pixnum);


    for(i = 0; i < width*height; i++){
                pBufOut[i] = (pLocalBufIn[i]) * 255;//output luma image   //I could only see this output
                }    
       }
    else
    {

/*nalysis_Begin=TRUE,Start Analysis. */

VLIB_subtractBackgroundS32(fgmask,        // new foreground mask to be computed
                               pLocalBufIn,         // the newest luma frame
                                 currentmeans,     // running mean
                                    currentVars,         // running variance
                                 thresholdGlobal,        // global threshold
                                 thresholdFactor,     // multiplicative factor for the image threshold
                                    pixnum);    

        VLIB_updateEWRMeanS32(currentmeans,
                            pLocalBufIn,
                            fgmask,
                            bgAdaptRate,
                            pixnum);
 
        VLIB_updateEWRVarianceS32(currentVars,
                                       currentmeans,
                                    pLocalBufIn,
                                    fgmask,
                                    bgAdaptRate,    
                                    pixnum);       

     Unpack32BitPackedBinImage(mask, width, height,pLocalScratch);  

    for(i = 0; i < width*height; i++){
                  pBufOut[i] = (pLocalScratch[i]) * 255;  //output analyzed image


        }
