3. Need for OMAP
 With the boom in mobile industry, the
expectations of cell phone users increased
 Customers wanted more and better multimedia
experience on their cell phones without losing
battery life
 Processors were required that can bridge these
paradoxical features by combining performance
and power management

4. Birth of OMAP
 Introduced by TI in 1999 as Open Multimedia
Application PlatformTM
 OMAP brought software applications to cell
phones
 Began shipping in year 2000
 Revolutionized the cell phone feature list by
providing all-in-one multimedia interfaces at low
power and operating system capability

5. OMAP Introduction
 Low power high performance multimedia
application processor offerings from TI for
wireless solutions
 Started out as single core solution with ARM7
and ARM9 as driving engine
 Later brought C55x DSP core to complement
ARM core
 Continuous enhancements made to enrich
multimedia experience and reduce power
