OMAP4 is way different from OMAP3.

OMAP3:
	Coretex-A8 UP
	Internal L2 cache
	DSP System
	IVHA 
OMAP4 - 
	Cortex-A9, Dual Core 
	External L2 cache ( PL310)
	New Interrupt controller(GIC)
	New Memory subsystem (EMIF)
	3 Additional co-procesors
	New DSS
	IVHA2

Except ARMv7 architecture, there is not much common between these two SOCs
