OMAP-L138: What are the key different between Syslink and IPC

I am currently working on omapl138 latest sdk  05_03_00_07, the user guide only talks about IPC but not Syslink.

Is it that this sdk does not work with syslink ? or IPC has replace syslink ?

If I need to upgrade the dsplink, should I consider Syslink or IPC ?

Thanks.
