How to call ARM application from DSP in OMAP L138

Hi All , 

1. We have an ARM side UPP application which i need to call from DSP . 

    This application is an ARM UPP sample application .It interacts with UPP driver on LINUX OS and gets the captured data. 

     This UPP data i need to send to DSP processor whenever DSP asks.

2. For our requirement , DSP acts like an master and ARM like BLACK BOX

    So the DSP should initiates the ARM application .The ARM application needs to provide the captured data

    back to DSP.Hence the data capturing and providing to DSP part is done from ARM side .

    DSP needs to call this function whenever it requires data from ARM .

Hope scenario is clear. Please do let me know if there is any available sample code available for the same .

Thank You,
