3.3.1 General description
The OMAPV1030 E-GPRS multimedia device belongs to the Texas Instruments OMAP-Vox_
processors family. It combines both a modem engine and an application engine. Memory and CPU
resources are shared between modem and application processing.
The OMAPV1030 chip is based on the OMAP3.4 architecture and integrates two processor
subsystems:
- An MPU subsystem based on an ARM926EJ-S
- A DSP subsystem based on a UMA 2.6 architecture integrating a C55x DSP core
The OMAPV1030's silicon process technology is a c027.0 90-nm digital CMOS.
