17 Other Appraches T Reducing Platfrm Dependencies Platfrm Abstractin Layers Wavefrm Platfrm Specific Applicatin inserts a layer between the wavefrm prper (smetimes referred t as the base wavefrm) and the platfrm/radi services handles unique message prcessing fr interfaces like 1553 and HTML 17

18 Platfrm Abstractin Layer Insert a Platfrm Abstractin Layer between the Base Wavefrm Applicatin and the Platfrm s. The Platfrm Specific Applicatin is implemented as a separate Applicatin that is launched first and then cnnected t the Base Wavefrm Applicatin. Cmm Channel When the Base Wavefrm Applicatin needs t run n anther radi, nly the Platfrm Specific Applicatin needs t be prted.
