• Integrated DSPs for video and audio processing
Many popular cellular handsets and PDA devices have been marketed based on the TI OMAP platform. Because they are based on an ARM core, these processors are supported by Linux today. Table 3-9 compares some of the more recent members of the TI OMAP family.
